PredANNpp-NMEDT-SongID-EncoderOnly-MuQ-pt10000-ft3500-seed42

Model description

This repository contains a PredANN++ encoder-only PyTorch Lightning checkpoint for NMED-T Song ID classification from 3-second EEG segments.

• Repository: Shogo-Noguchi/PredANNpp-NMEDT-SongID-EncoderOnly-MuQ-pt10000-ft3500-seed42
• Checkpoint file: predannpp_nmedt_songid_encoderonly_muq_pt10000_ft3500_seed42.ckpt
• Stage: pretraining + finetuning
• Target / teacher representation: MuQ acoustic embedding
• Architecture: Encoder-only Song ID classifier
• Pretraining: 10k epochs with 50% masking
• Finetuning: 3.5k epochs for Song ID classification
• Random seed: 42
• SHA256: 7eab2d06d24b62044a368525ae6cd168e99559cf405d064e407079bc632952a9

This checkpoint is a task-specific Song ID classifier. It directly maps a 3-second EEG segment to 10-class Song ID logits.

Capabilities

• Input: 128-channel EEG, 125 Hz, 3-second segments.
• Output: 10-class Song ID logits.
• Intended module type: encoder-only finetuning module.

For masked teacher-token prediction, use a PredANNpp-Pretrain-* checkpoint instead.

Training data

• Dataset: NMED-T (Naturalistic Music EEG Dataset – Tempo), 10 songs, 20 subjects, trial=1.
• Teacher / target source: MuQ acoustic embeddings.

Training procedure

1. Multitask pretraining with masked teacher-token prediction and auxiliary Song ID learning.
2. Encoder-only finetuning for NMED-T Song ID classification.

Intended use

• Reproducing PredANN++ Song ID classification experiments.
• Evaluating EEG-based music identification from 3-second EEG segments.
• Comparing acoustic and expectation-related teacher representations.

Not intended use

• Medical diagnosis, clinical decision making, or biometric identification.
• Commercial use without checking the PredANN++ code license, NMED-T terms, and upstream model/feature licenses.
• Masked-token pretraining evaluation; this repository contains a finetuned encoder-only classifier.

License and upstream dependencies

This checkpoint uses MuQ model weights / features. The checkpoint is released under CC-BY-NC-4.0 for compatibility with NMED-T-derived training artifacts and upstream feature dependencies.

Reproducibility notes

• metadata.json stores standardized release metadata.
• SHA256SUMS stores the checkpoint checksum.
• Use the PredANN++ GitHub repository for model definitions and evaluation scripts.
