# ENCODE ChIP-seq Vetorizado
Saída do pipeline de vetorização do [fabricioslv/encode-chip-seq-subset](https://huggingface.co/datasets/fabricioslv/encode-chip-seq-subset).
## 3 estratégias
### Stage 1 — Bins fixos (10kb)
Matriz densa `(n_bins × n_tracks)` por cromossomo. Formato: `.npz`.
### Stage 2 — Peak detection (5σ) + embeddings
Picos detectados por threshold estatístico. Embedding de 9 features por pico.
Formato: `peaks.tsv` + `embeddings.npz`.
### Stage 3 — Janelas sliding (10kb, stride 5kb) + DL tensors
Tensores normalizados (z-score) prontos para CNN/Transformer. Formato: `.h5`.
## Parâmetros
- Bin size: 10000 bp
- Peak threshold: 5.0σ
- Window: 10000 bp, stride: 5000 bp
- Sub-sampling: 100 pontos por janela (Stage 3)
- Device: cpu
