| """HF Job (a100-large): zero-shot intfloat/multilingual-e5-large embeddings for all 24.2M normalised records. |
| |
| Spec (matches the validated zero-shot evaluation): |
| * sentence-transformers, model loaded in float16 on CUDA, prompt "query: " on every text, normalize_embeddings=True |
| * variant "full": raw_name.strip() + " | " + raw_address.strip() (just the name when the address is empty), max_seq_length=80 |
| * variant "name": raw_name.strip(), max_seq_length=32 |
| * batch_size 512; sentence-transformers length-sorts inside each encode() call and restores the original order. |
| Each table is fed to encode() in contiguous chunks of CHUNK rows (for progress logging and bounded host memory); |
| rows are never reordered. |
| * output per table: emb/e5_{variant}/{table}.npy (float16, shape (n_rows, 1024), parquet row order) |
| emb/e5_{variant}/{table}_ids.parquet (entity_id, same order) |
| * order: variant "full" for s1,s2,s3,t1,t2,t3, then variant "name"; each table is committed to the Hub |
| (Arushhh/amlc-work, dataset) as soon as it is written, in a background thread so the GPU keeps working. |
| Job splitting (env): TABLES=s1,s2,s3 restricts the job to those tables (default: all six, in the order above); |
| JOB_TAG names this job's manifest emb/e5_manifest_{JOB_TAG}.json (default emb/e5_manifest.json); |
| SKIP_EXISTING=1 (default) skips a variant/table whose .npy (exact expected byte size) and _ids.parquet are already on the Hub. |
| In-job integrity checks per table: shape/dtype via np.load(mmap), non-finite count, min/max L2 norm over all rows, |
| and an order check (256 random rows re-encoded on their own must have cosine > 0.99 with the stored rows). |
