Joint SpeakerID INT8 (weight-only)
INT8 weight-only quantisation of the Joint Speaker Identifier from adobe-research/speaker-identification (Interspeech 2024).
This checkpoint is a quantised child of Adobe Research’s original Joint Speaker Identifier (FP32). The architecture and trained weights are Adobe’s; only the Linear weights were packed to INT8 (group size 64). No additional training.
| Metric | Value |
|---|---|
| Precision | 78.87 |
| Δ vs FP32 parent | 0.00 |
| F1 | 63.28 |
| Accuracy | 67.60 |
| Throughput | 18.34 examples/s (Apple M3 Pro, MPS, batch 2) |
| In-memory size | 472 MB (FP32 parent: 1633 MB) |
Same precision, F1, and accuracy as the FP32 Joint parent at about 3.5× smaller weights.
