## What it does

This skill runs the deterministic DEFT embed-then-mine pipeline for VCN AOI tasks. It embeds target gap images from a Parquet file, embeds candidate pool images with the same encoder, and performs k-NN nearest-neighbour mining. Mined samples can then feed downstream model retraining.

Under the hood, the skill executes three direct `docker run` calls against the pinned TAO data-services container. It also uses a host Python script, `scripts/filter_mined_history.py`, to eliminate samples selected during previous iterations. Do not run the container with `--user $(id -u):$(id -g)`; this causes a `transformers` `KeyError` on startup.

Running this workflow requires a CUDA GPU, Docker, and the nvidia-container-toolkit. Without a working GPU, both the SigLIP embedding passes and the cuML k-NN search will fail immediately. Since the container runs as root, ownership of output Parquet files must be updated on the host with `chown`.

## Install

### Claude Code (native platform)

npx skills add NVIDIA/skills --skill tao-mine-aoi-images -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/tao-mine-aoi-images/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/tao-mine-aoi-images/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill tao-mine-aoi-images -a codex
```

2. **Manually: put the files in place**

## When to use it
- mine nearest-neighbour defect images from a source pool
- generate image embeddings using SigLIP in the TAO data-services container
- run GPU-accelerated k-NN search with cuML
- filter out previously mined images across iterative training rounds

## Example prompts
- Run tao-mine-aoi-images using mining_gaps.parquet and our source_pool.parquet
- Execute the DEFT mining workflow with topn set to 5 and cosine metric
- Mine nearest neighbours from the pool and filter duplicates with scripts/filter_mined_history.py

# DEFT Mining and Embedding Skill

> **Standalone install?** If this session was not initialized by the TAO skill bank plugin, run the `tao-setup` skill first (host preflight, credentials, cross-skill discovery).

You are the operator of the DEFT embed-then-mine workflow for VCN AOI. Your job is to take a parquet of weak target images (the gap-analysis or routing output) and a source pool, then produce a deduplicated parquet of mined source images that look similar to the targets — ready to feed into the next training round. Iterative DEFT callers also run the bundled history-aware post-processing step so a sample selected in an earlier iteration is not selected again.

The workflow is fixed and deterministic: **embed the targets, embed the source pool, mine nearest neighbours, then (for iterative workflows) remove previously mined samples.** Each GPU step's output parquet is the next step's input; history-aware selection is a host-side post-processing step, not another k-NN search. There is no clustering pass or human-in-the-loop selection — depth comes from picking the right encoder and a `topn` wide enough to leave novel candidates after history filtering.
