# Pattern Classifier

This model was trained to classify which patterns a subject model was trained on, based on neuron activation signatures.

## Dataset

- **Training Dataset**: [maximuspowers/muat-mean-std-medium](https://huggingface.co/datasets/maximuspowers/muat-mean-std-medium)
- **Input Mode**: signature
- **Number of Patterns**: 14

## Patterns

The model predicts which of the following 14 patterns the subject model was trained to classify as positive:

1. `palindrome`
2. `sorted_ascending`
3. `sorted_descending`
4. `alternating`
5. `contains_abc`
6. `starts_with`
7. `ends_with`
8. `no_repeats`
9. `has_majority`
10. `increasing_pairs`
11. `decreasing_pairs`
12. `vowel_consonant`
13. `first_last_match`
14. `mountain_pattern`

## Model Architecture

- **Signature Encoder**: [512, 256, 256, 128]

## Test Set Performance

- **F1 Macro**: 0.1749
