Bridge

Making a bridge between NLP models and Brain data

This repository includes codes for:

  • Comparing and evaluating representational spaces (e.g. internal states of language encoding models) using RSA and ReStA.
  • Using internal states of a pretrained language model to predict brain activations.

Publication:

Blackbox meets blackbox: Representational Similarity and Stability Analysis of Neural Language Models and Brains

Requirements:

files:

Path to the raw brain data, e.g.: '/Users/samiraabnar/Codes/Data/harrypotter/'

Spacy model file for tokenization: python -m spacy download en_core_web_lg

How to obtain contextualized representations from different models:

python encode_stimuli_in_context.py

How to run predictive modelling experiments:

python run_experiment.py

How to run RSA experiments:

python rsa/compute_rep_sim.py

Link to colab for plotting the results:
