Zorrojurro/thermal-pattern-analysis

Thermal Pattern Analysis — CNN + Bi-LSTM

Anomaly detection model for infrared thermal images of power transformers.

Architecture

3-stage pipeline:

1. Feature Extraction — Modified ResNet-18 (grayscale input, 256-dim embeddings)
2. Temporal Analysis — Bidirectional LSTM + Self-Attention (128 hidden, 2 layers)
3. Anomaly Detection — Cosine similarity scorer (threshold: 0.7)

Usage

import torch
from huggingface_hub import hf_hub_download

ckpt_path = hf_hub_download("Zorrojurro/thermal-pattern-analysis", "best_model.pt")
ckpt = torch.load(ckpt_path, map_location="cpu", weights_only=False)
# model.load_state_dict(ckpt["model_state_dict"])
# classifier.load_state_dict(ckpt["classifier_state_dict"])
