Mathematical Capabilities of ChatGPT

2 code implementations NeurIPS 2023 Simon Frieder, Luca Pinchetti, Alexis Chevalier, Ryan-Rhys Griffiths, Tommaso Salvatori, Thomas Lukasiewicz, Philipp Christian Petersen, Julius Berner

We investigate the mathematical capabilities of two iterations of ChatGPT (released 9-January-2023 and 30-January-2023) and of GPT-4 by testing them on publicly available datasets, as well as hand-crafted ones, using a novel methodology.

Predictive Coding beyond Gaussian Distributions

no code implementations7 Nov 2022 Luca Pinchetti, Tommaso Salvatori, Yordan Yordanov, Beren Millidge, Yuhang Song, Thomas Lukasiewicz

A large amount of recent research has the far-reaching goal of finding training methods for deep neural networks that can serve as alternatives to backpropagation (BP).

Learning on Arbitrary Graph Topologies via Predictive Coding

no code implementations31 Jan 2022 Tommaso Salvatori, Luca Pinchetti, Beren Millidge, Yuhang Song, TianYi Bao, Rafal Bogacz, Thomas Lukasiewicz

Training with backpropagation (BP) in standard deep learning consists of two main steps: a forward pass that maps a data point to its prediction, and a backward pass that propagates the error of this prediction back through the network.

Unifying Categorical Models by Explicit Disentanglement of the Labels' Generative Factors

no code implementations29 Sep 2021 Luca Pinchetti, Lei Sha, Thomas Lukasiewicz

By doing so, it is possible to merge multiple datasets based on different categorical models by projecting the data points into a unified latent space.
