LCNet-meta-modeling

This is the repo for the following paper:

Lu, Q., Nguyen, T. T., Zhang, Q., Hasson, U., Griffiths, T. L., Zacks, J. M., Gershman, S. J., & Norman, K. A. (2023). Reconciling Shared versus Context-Specific Information in a Neural Network Model of Latent Causes. In arXiv [q-bio.NC]. arXiv. http://arxiv.org/abs/2312.08519

This repo contains the code for Simulation 3 using the META data.

code dependency

In additional to the dependencies related to the META data (here), a reasonably up-to-date version of pytorch is needed.

to replicate the results:

To replicate the results, a computing cluster is needed. We used slurm.

On the cluster, run the following code under src

./submit-train.sh

Once model training is done, run the following code under src

./submit-eval-group.sh 

Once model evaluation is done, you can find the results under the logging directory you specified in eval-group.sh (i.e., here).
