My Implementation of RATE

This repository contains a PyTorch implementation of the Recurrent Action Transformer with Memory (RATE) model, as described in the paper "Recurrent Action Transformer with Memory".

Components

The implementation consists of the following modules:

1. mrv.py: Defines the MemoryRetentionValve module, which handles the multi-head attention-based memory update.
2. ct.py: Defines the CausalTransformer module, which is the transformer-based encoder component.
3. rm.py: Defines the overall RATEModel class, which combines the MemoryRetentionValve and CausalTransformer modules.
4. train.py: Contains the training loop for the RATE model, including loss calculation and visualization of the results.

Usage

To train the RATE model, run the train.py script. This will train the model on the provided dummy data and plot the training loss and memory evolution over epochs.

Might Change or Add

• Change: Probably seperate the Observations, Actions, and Returns-To-Go encoders as seperate modules.
• Add: A CartPole demo using the RATEModel (too lazy rn)
