# AntiCheatPT_256

This Model is the best performing transformer-based model from the thesis: 
AntiCheatPT: A Transformer-Based Approach to Cheat Detection in Competitive 
Computer Games by Mille Mei Zhen Loo & Gert Luzkov.

The thesis can be found [here](https://github.com/Pinkvinus/CS2_cheat_detection/blob/main/AntiCheatPT%20A%20Transformer-Based%20Approach%20to%20Cheat%20Detection%20in%20Competitive%20Computer%20Games.pdf)
