About xLSTM
xLSTM is a cutting-edge Recurrent Neural Network (RNN) architecture inspired by the original Long Short-Term Memory (LSTM), but enhanced with new mechanisms for improved performance. By incorporating Exponential Gating, advanced normalization techniques, and a Matrix Memory, xLSTM addresses the inherent limitations of traditional LSTM models and demonstrates notable improvements in Language Modeling tasks compared to Transformers or State Space Models.
Installation Guide
Minimal Installation
Create a conda environment using the `environment_pt220cu121.yaml` file.
Install the xLSTM module as a package:
- Via pip.
- Cloning from GitHub.
Requirements
This package relies on PyTorch (tested for versions >=1.8). For the CUDA version of xLSTM, ensure your system has a Compute Capability >= 8.0. Refer to the CUDA GPUs for compatibility details. For a robust setup, it's advised to use the provided `environment_pt220cu121.yaml`.
Usage
For non-language applications or integration into other architectures, use `xLSTMBlockStack`.
For language modeling or token-based applications, employ `xLSTMLMModel`.
xLSTM Block Stack
Ideal for use as an alternative backbone in existing projects, akin to a stack of Transformer blocks but based on xLSTM blocks. You can configure it using yaml strings/files and employ tools like dacite for creating config dataclasses.
The xLSTMBlockStack configured for integration.
xLSTM Language Model
The `xLSTMLMModel` is essentially a wrapper around the `xLSTMBlockStack`, incorporating token embedding and language model heads, making it specifically tailored for language-based tasks.
Experiments
To assess the potential of xLSTM over the traditional LSTM variants, synthetic experiments are conducted. For instance:
Parity Task: Demonstrates state-tracking capabilities provided by sLSTM.
Multi-Query Associative Recall Task: Highlights the matrix-memory and state expansion benefits of mLSTM.
These experiments validate the significant advancements provided by the xLSTM in various challenging tasks.
Example command to run experiments:
```bash
python main.py --config experiments/config.yaml
Note: The provided training loop does not include early stopping or test evaluations.
