A project needs the same occurrences again later: comparing two classifiers only means something if both saw the same rows, and a review pass wants the list it started from. A filter answers differently as data arrives, so the membership is stored rather than described. An OccurrenceSet holds its occurrences and the projects it belongs to. A set with no project is global and is offered everywhere, following how TaxaList already treats a list with no project. Membership is decided when the set is created and nothing adds to or removes from one afterwards, because anything recorded against a set was measured on exactly those occurrences. Creating, renaming and deleting are gated on new project permissions, held by the roles that already curate a project's data. A global set has no single project to check against, so it cannot be edited through the API at all. The occurrence list takes an occurrence_set filter, and the sets are offered as choices the same way capture sets are.
Adds the occurrence set to the occurrence filter panel, picked from the set choices endpoint the same way a capture set is. A set is only useful if you can look at what is in it, and this is where someone reviewing one starts. The field is carried over from other views like the existing filters, so arriving with a set already chosen shows it in the panel where it can be cleared.
Someone filtering the occurrence list to the rows they care about had no way to keep that selection. Selecting occurrences now offers saving them as a set, next to the identification actions already there. The action does not change any occurrence, so it is not behind update rights on them; the endpoint gates it on the project's own permission instead.
Registering a filter in the shared list is not enough for it to appear: the occurrences page renders one FilterControl per field it offers, and the set was missing from that list, so the filter existed everywhere except on screen. It sits under More filters beside the capture set, and that section now opens on arrival when a set is already applied, as it does for the other filters there.
The selection bar holds identification actions and is hidden from anyone without update rights on the occurrences, so saving a set — which changes none of them — was unavailable to a reader who could still create one. It also sat there as an unlabelled icon among three others. It now sits beside Export as a labelled button, and appears only while something is selected, since that is the only time it does anything.

Can the backend post a training result periodically instead of only at the end? Or another type of progress payload? That way the job won't get reaped, and the user can see that something is happening. Something like the wandb progress callbacks.

Occurrence-set listing does not check whether the caller may see the project.
Draft-project occurrence sets can leak to non-members. The list permission accepts any existing project_id. When a project is active, get_queryset uses for_project and does not apply visible_for_user. As a result, any caller, including an anonymous one, can list the names and sizes of a draft project's sets.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win
The duplicate-result guard is a non-atomic check-then-act.
record_result re-reads status and only then registers a version and saves. Two deliveries can run at the same time: the training-result callback and the inline dispatch path, or two callback retries. If both read STARTED before either one saves, both call register_new_version. Each call creates its own AlgorithmCategoryMap and Algorithm row with consecutive version numbers, which is the duplicate the comment says this code prevents. The guard holds only if the service waits for the callback response before it returns from /train, and the code does not enforce that. Take a row lock for the check and the write.

Already-registered algorithms never receive the service's training_config.
Migration 0031 gives every existing Algorithm row the default AlgorithmTrainingConfig. The and _created guard then blocks the service-declared config on every later re-registration. Here is the trigger: an algorithm was registered before this PR, and the service now publishes training_config with its own epochs, head_type, or learning_rate. In that case Antenna keeps the module defaults permanently, and send_training_request sends those defaults to the service. Seed the config whenever the stored config still equals the untouched default. This keeps admin edits safe.

count_missing_embeddings ignores occurrence_set and key.
The function accepts occurrence_set but calls verified_occurrence_ids(project) without it. When a set is selected, the summary endpoint and TrainingDatasetMetadata.verified_detections_without_embedding therefore report missing embeddings for the whole project. Screenshot 6 shows this: the warning stays at 1 after the set narrows the data. The job log then also warns about detections that were never part of the run. The .exclude also does not filter on key=DEFAULT_EMBEDDING_KEY. A detection with only a non-default key is therefore counted as embedded, but verified_training_rows does not use it.

The summary's rows, train and test include crops that a run drops.
build_training_dataset keeps only rows whose label is in class_index. class_index comes from the taxa list (project.default_taxa_list) or from species with at least min_per_species crops. summary counts and splits every row in verified_training_rows, and it never applies the project's default taxa list. Screenshot 8 shows the result: "11 verified crops… covering 1 species", although some of those crops belong to the dropped species. The preview can show a usable split while the run fails with NotEnoughVerifiedData because one side is empty. Resolve the same class set that the build uses, and count only rows in that set.

Update the summary logic around `label_counts`, `species_with_enough_examples`,
and `verified_training_rows` to resolve the same class set as
`build_training_dataset`: use the project’s default taxa when configured,
otherwise apply `min_per_species`. Filter rows to that set before calculating
`rows`, `train`, and `test` so the preview matches the dataset build.

Replace any with a typed ServerTrainingSummary interface in data-services/models/.
The new endpoint payload is typed as any. A renamed or missing server field is then not caught at compile time. The server returns trainable_classes, occurrences, rows, train, test and verified_detections_without_embedding. Declare these fields in an interface in src/data-services/models/ and import it here.

Retraining needs two things an algorithm did not carry: whether the processing service can retrain it at all, and the settings to retrain it with. Asking the service on every page load would make the UI depend on the service being up, so both are mirrored onto the algorithm when it registers. The config is seeded from the service and then owned here, so an admin's edits survive the next /info read. The settings are split on purpose: Antenna reads the dataset half when it builds the training set and passes the fitting half through, since the service owns the fitting. for_run() takes a job's params on top of the config and checks them, because a test_fraction outside (0, 1) either holds out everything or scores a head on the rows it just learned, and both finish looking like a successful run. training_info is the other direction: every retrain makes a new algorithm version, so each version records where its weights came from.
The trainable flag and the training settings were on the algorithm but nothing ever filled them: a service could say it retrains a head and Antenna stored false anyway, so the job form offered nothing and the job refused every algorithm. Found by registering a real service that does report both. They now come from the /info response at registration, like task_type and uri. The settings are seeded only when the algorithm is new, so an admin's edits are not overwritten the next time the pipelines are re-registered. AlgorithmTrainingConfig moves up the module because the config response now refers to it.
The training job form offers a classifier to retrain, and listing every algorithm in the project would offer detectors and heads no service can train. The flag is already mirrored from the service, so the list endpoint now filters on it.
…go quiet Four things a job type knows about itself that nothing could ask it: ``required_fields`` and ``required_params`` are what a job of this type cannot run without, so a gap becomes a 400 when the job is created rather than a failure minutes later in a worker. ``user_creatable`` says whether a person starts one by hand, since the rest are made by the platform as a side effect of something else and nothing should offer those as a choice. ``stalled_after_minutes`` is how long one may go untouched before the stale check calls it dead, which the default of ten minutes gets wrong for any type that waits on something external. Declared here on their own; the checks that read them follow.
A job form had no way to send a type's own settings: params were readable on the model and absent from the serializer, so which algorithm to retrain and what split to hold out could not reach the API at all. They are now one writable field rather than a column per type, because only the type knows what its params mean. Creation also refuses a job its type could not run, naming the setting that is missing. The alternative is a worker discovering the gap minutes later, which leaves a failed job in the list and a person guessing what they got wrong. Not enforced: user_creatable. Several types the platform creates as a side effect are also posted directly by existing clients, so it says which types a job form should offer, which is the UI's question rather than the API's.
The stale sweep fails any job untouched for ten minutes. A job that hands work to an external service and waits to be called back writes nothing to its own row meanwhile, so for those types silence is not evidence that the job died, and a training run that takes an hour was being marked lost while it was still running. Candidates are still gathered at the default, then each is judged against the deadline its own type declares. The type is looked up rather than read off the job, so an unrecognised job_type_key leaves that one job alone instead of raising and stopping the whole sweep.
…t/retrain-training-set
Training is run per project and rewrites what every later identification is compared against, so it belongs behind its own permission rather than any existing run_*_job one. ML data managers get it with the other job permissions they already hold; the migration grants it to the groups that exist today so current managers do not lose the ability when the job appears.
A head trained only on the species someone happened to verify cannot predict the rest, so a region's expected species have to come from somewhere other than the verified data. The project now names that list, and training reads it as the class list. It is optional: without one, the classes are whatever has been verified.
A head is only worth retraining on the crops a person has already named, so this collects verified detections together with the embeddings stored for them and writes one dataset file per run. Decisions worth knowing about: The train/test split is grouped by occurrence, not by detection. Crops from one occurrence are near-identical frames of the same insect, so splitting per detection puts the same animal on both sides and the held-out score flatters the head. It is also a hash of the occurrence id rather than a random draw, so the held-out set stays the same between runs and two heads can be compared. The vector width is read from the stored vectors rather than assumed, because the embedding column is unsized and two algorithms may differ. Species with too few verified crops are dropped, since one example cannot be both trained and evaluated on. The classes come from the project's taxa list where it has one, so the head covers the region and not only what has been verified, and the classes with no verified data are recorded in the file rather than silently left out. The metadata is declared as a schema instead of assembled as a dict, so the shape is checked once here rather than at every reader, and the processing service echoes it back for the job to store. The rows are also served over the API, paged at a limit set for their size: a 1024-dimension vector is roughly 20 KB of JSON, so the platform default of 10 is useless and no limit at all returns hundreds of megabytes.
The training job form asks for a split ratio and an optional occurrence set. Both questions are unanswerable without knowing what is there, so the summary endpoint now answers for exactly the run being set up. It takes the occurrence set, or reports every verified occurrence when none is chosen, which is what a run without a set does. It defaults the settings to the algorithm's own training config rather than to module defaults, so the first numbers someone sees are the numbers a run would use, and it accepts the settings as parameters so the form can preview a changed ratio without starting a job. The same bounds a job is held to are applied here, since stats computed under settings no run could use are worse than no stats. It also reports the classes that survive min_per_species, and names the species dropped: a raw class count overstates what the head would come out knowing. While adding the set parameter: the endpoint was gated on project visibility, which a non-draft project grants to everyone, so any account could read every verified label in a project together with the vector for each crop. It is now gated on the same permission as the training job.
Adds the training job: it builds the dataset, hands a processing service the URL, and records what comes back as a new algorithm version. Training outlasts the request that starts it, so the service reports its result to a callback instead of the connection being held open. The service has no Antenna account, so the callbacks are authorised by a signed token issued when the job was dispatched, and the job is looked up directly because project visibility would refuse an unauthenticated caller. The weights are uploaded the same way: without that, the head exists only in a cache directory on the service's disk and Antenna records a version it cannot point at. An upload is refused once the job has finished, since the token lasts a day and the path is fixed by the job, so otherwise the weights behind a registered version could be swapped out after the run ended. A job type now also declares what it needs before it can start and whether a user may create it at all, rather than each job discovering a missing param partway through its own run.
The refactor that gathered the training modules into one package left two imports behind, so running a training job raised ImportError on ami.ml.training_dataset instead of building a dataset. The tests did not catch it because neither import is reached until a job actually runs.
Requiring a set meant that retraining on everything verified so far - the ordinary case - first made someone save a set of everything, which is a step with no decision in it. A job without a set now learns from every verified occurrence in the project. The dataset file records which set was used, or that there was none, so a run is still legible afterwards either way. Naming a set is still worth doing when it matters: a set is fixed once created, so that run can be repeated.
A key is shared by every version of an algorithm, while embeddings are stored against one version row. Taking whichever row the database returned first could pick an older version and train on an empty set of vectors, or on vectors from a different fitting, with nothing in the job to say which had happened.
Training is the long stage of the job and the service says nothing while it runs, so the bar sat at nought for as long as the fitting took and a person could not tell a slow run from a dead one. The service is now told where to report, and posts the epoch it has reached. The callback is authorised by the same signed token as the result and the head upload, since a service has no Antenna account. The epoch and the total land as stage parameters, and the stage progress is the ratio of the two. The total is written at dispatch from the run's own settings, so the stage reads "0 of 5000" while the service is still starting rather than an empty pair. A ping never finishes the stage: the result does, because the service still has to score the head and upload it after the last epoch. Pings that arrive late or out of order are dropped rather than dragging a run backwards. Reporting is optional. A service that does not post anything behaves exactly as before, and a ping that fails to send must not fail the run.
The training request was a dict literal and the result was read with .get() at a dozen call sites, so neither side of the exchange was written down anywhere. Every other service contract in this module is a schema; this one was the exception, and a service renaming a field would have produced an empty metrics dict and no error. TrainingRequest and TrainingResult mirror the service's own TrainRequest and TrainResponse, the way PipelineRequest and PipelineResultsResponse already do for processing. TrainingResult keeps unknown fields: a newer service may report more than this one knows about, and the result is the only record of what a run did. incumbent_metrics is nullable because a service reports null when there was no current head to score, which is exactly what a first retrain does.
… to read A result could arrive two ways: in the body of the /train response, or at the job's callback. The two carried the same outcome in different shapes, and both of these bugs lived in that gap. On the callback path the dataset metadata the service echoes was read as payload["dataset"]["metadata"], which is not where it is, so it was never parsed and a registered version never recorded which occurrence set it learned from. The provenance this is all for was quietly dropped on every real run. On the inline path the same code would have raised AttributeError, because there "dataset" is the schema object rather than a dict. It never fired only because a service posts its callback first and the duplicate guard returned early. /train is now an acknowledgement: the result arrives at the callback, is validated by a serializer at the view, and record_result takes the parsed result rather than a raw payload. One shape, one path, parsed once at the boundary. The result is validated because the new algorithm version is built from it. The echoed dataset metadata is read leniently: a service echoing an older shape should still have its result recorded, and the cost is a version that cannot say which set it came from, not a head that is lost. Also fixes a flaky test: with a handful of rows, a hash split does not give a particular ratio a particular count, so the ratio is now compared across two values rather than asserted exactly.
Every training job read as "internal", the mode for work the platform does itself, because Job.setup() decides the mode from the pipeline and a training job has none. It is the platform's own word for what this job has always done: hand the work to a service and wait to be called back.
The job form only made processing jobs. Retraining had to be posted by hand, which put it out of reach of the people the feature is for. The form now asks for the job type first, and the processing fields and the retraining fields are the two branches of that choice. Retraining asks for the algorithm, an optional occurrence set, and the two settings worth changing per run. The occurrence set is optional and empty means every verified occurrence in the project, which is the ordinary case. A split ratio is unanswerable without knowing what is behind it, so the form reports what the run would learn from - crops, occurrences, species, and how the split falls - and re-reads it as the set or the ratio changes. Verified crops with no embedding from the chosen algorithm are called out, since they are silently left out of the run.
Leaving a setting empty means "use the algorithm's own", but the empty field was sent as an empty string, which the job then tried to read as a number and failed on at run time. Empty fields are left out of the params instead. A ratio outside the valid range is also no longer asked about: the field already reports it, and the summary request behind it could only come back as an error.
The list reads its type labels from a map that the new type was missing from, so every retraining run showed a blank Type while the API was already naming it.

Retrains a classifier head from the species people have verified, and lets someone start that run from the job form.
The head is retrained, not the backbone. The backbone is frozen, embeddings are stored once per crop, and a run reads those rather than the images.
Where it sits
Stacked on two branches:
feat/detection-embeddings-task(Store feature vectors from any model for every detection, indexed for the ways they are read #1462), which stores the embeddings this trains onfeat/occurrence-sets(Keep a fixed list of occurrences as a set, and make one from the occurrences page #1492) is merged in, since a run can name a set to learn fromSo the diff here carries #1492's commits too. Land both first.
This is the retraining slice carved out of #1407.
What a run does
Decisions worth a look
The split is grouped by occurrence, and hashed, not drawn at random. Crops from one occurrence are near-identical frames of the same insect, so splitting per detection puts the same animal on both sides and the held-out score flatters the head. Hashing the occurrence id keeps the held-out set the same between runs, so two heads can be compared.
The occurrence set is optional. Empty means every verified occurrence in the project, which is the ordinary case; naming a set makes a run repeatable. The dataset file records which it was.
The class list comes from the project's taxa list when it has one. A head trained only on what someone happened to verify cannot predict the rest. Classes with no verified data are recorded in the file rather than dropped silently.
Training outlasts the request that starts it. The service reports to a callback authorised by a token Antenna signed when it dispatched, since the service has no account here. The head is uploaded the same way; without it the weights live only in a cache directory on the service's disk.
A job type now says how long it may go quiet. The stale sweep failed anything untouched for ten minutes, which killed healthy training runs waiting on a callback.
The job form
Asks for the job type first; processing and retraining are the two branches of that choice. Retraining asks for the algorithm, an optional set, and the two settings worth changing per run.
A split ratio is unanswerable without knowing what is behind it, so the form reports what the run would learn from and re-reads it as the set or the ratio changes:
Verified crops with no embedding from the chosen algorithm are called out, since the run leaves them out.
The form, step by step
The type is the first question, and retraining is the other branch of it:
Only algorithms a processing service reports as trainable are offered:
With no set chosen, the numbers are every verified occurrence in the project. Crops with no embedding from this algorithm are named rather than quietly dropped:
Choosing a set narrows them to that set:
The settings are editable per run, and the numbers follow. A held-out share of 0.5 moves the split:
Raising the minimum crops per species drops the species that cannot be learned, and says so:
A setting no run could use is refused on the field:
Two runs, one on everything verified and one from a set:
A run, end to end
Against the BioCLIP 2.5 service on the GPU VM, over a project's real verified crops. Three stages: the set is built here, the service trains, and the result comes back through the callback.
The logs say what it learned from and what it decided:
The last line is the point of keeping the score: a retrain that is worse than what it would replace says so rather than quietly taking over.
Progress while it trains
Training is the long stage and the service was silent while it ran, so the bar sat at nought and a slow run looked like a dead one. The service now posts the epoch it has reached, authorised by the same signed token as the result callback, and the stage follows it.
The epoch and the total are stage parameters, so the stage says where it has got to and not only how far along the bar is:
The total is written at dispatch from the run's own settings, so the stage reads "0 of 5000" while the service is still starting. A ping never finishes the stage - the result does, since the head still has to be scored and uploaded after the last epoch. Late or out-of-order pings are dropped rather than dragging a run backwards.
Reporting is optional: a service that posts nothing behaves exactly as before, and a ping that fails to send is logged and dropped rather than failing the run. The service side is ami-data-companion#167.
The logs of one of those runs, end to end against the GPU service:
That run is against a seeded project, so the numbers are small on purpose; the point is that the guards say so rather than presenting a head trained on eleven crops as an improvement.
The service-to-job interface
A retraining run reports back the way an ML job's results already do: a POST to a route on
the job, typed with a pydantic schema and a serializer, acknowledged with a typed response.
TrainingRequestandTrainingResultmirror the service's ownTrainRequestandTrainResponse, asPipelineRequestandPipelineResultsResponsealready do forprocessing. The job is marked
ASYNC_API, which is what it has always been.There is one way in.
/trainreturns202 accepted; the result arrives only at thecallback, parsed once. Antenna previously also read a result from the
/trainresponsebody, which gave the same outcome two shapes - and both of the bugs this fixes lived in
that gap. On the callback path the dataset metadata was never parsed, so a registered
version never recorded which occurrence set it learned from; on the inline path the same
code would have raised
AttributeErrorhad the duplicate guard not hidden it.Three things here have no precedent in the platform, and are worth a look:
job, valid for 24 hours. The existing async path does it the other way round: the ADC
worker holds an Antenna API token and posts results as itself. I kept the signed token
because it is the tighter of the two - scoped to one job, expiring - and because
POST /jobs/{id}/result/resolves to aresult_ml_jobpermission that does not exist,so in practice that endpoint needs a superuser account. Happy to switch to a service
token if you would rather have one mechanism; it is a small change either way. The
permission on the existing endpoint looks unintended and may deserve its own fix.
training run has nothing to infer from, so the service reports its epoch.
Noted while in here
The training-data endpoint was gated on project visibility, which a non-draft project grants to everyone, so any account could read every verified label in a project together with the vector for each crop. It is now gated on the same permission as the training job.
The
trainableflag and the training settings were on the algorithm but nothing ever filled them: a service could report that it retrains a head and Antenna stored false anyway, so the form offered nothing. They now come from the service's /info at registration, like task_type and uri.Testing
