# Introduction

This repository contains the checkpoints of ICLR 2025 paper **[“Polynomial Composition Activations: Unleashing the Dynamics of Large Language Models](https://arxiv.org/pdf/2411.03884)”.**
In this work, we introduce a novel activation function called **Polynomial Composition (PolyCom)**, which enhances the expressiveness of large language models (LLMs) through dynamic polynomial compositions. Our method significantly improves the performance of dense and mixture of experts (MoE) models across a variety of downstream tasks, without adding significant computational overhead.

# Datasets and Training

We use the [RedPajama-Data-1T](https://huggingface.co/datasets/togethercomputer/RedPajama-Data-1T) dataset and pretrain the PolyCom model on 250B tokens. For more training details, please refer to [the source code](https://github.com/BryceZhuo/PolyCom).


# Inference

Here is an example of how to use the PolyCom model for inference:

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained(path_of_model, device_map="cuda",trust_remote_code=True)
tokenizer = AutoTokenizer.from_pretrained(path_of_model, padding_side="right",trust_remote_code=True)

prompt = "Hello, my name is"
input_ids = tokenizer.encode(prompt, return_tensors='pt').to('cuda')

greedy_output = model.generate(input_ids)
print(tokenizer.decode(greedy_output[0], skip_special_tokens=True))
```
