SciFix: Outperforming GPT3 on Scientific Factual Error Correction

1 code implementation24 May 2023 Dhananjay Ashok, Atharva Kulkarni, Hai Pham, Barnabás Póczos

Our method outperforms the very LLM that was used to generate the annotated dataset -- with Few-Shot Prompting on GPT3. 5 achieving 58%, 61%, and 64% on the respective datasets, a consistently lower correction accuracy, despite using nearly 800 times as many parameters as our model.

PromptNER: Prompting For Named Entity Recognition

no code implementations24 May 2023 Dhananjay Ashok, Zachary C. Lipton

In a surprising turn, Large Language Models (LLMs) together with a growing arsenal of prompt-based heuristics now offer powerful off-the-shelf approaches providing few-shot solutions to myriad classic NLP problems.

A Solver + Gradient Descent Training Algorithm for Deep Neural Networks

no code implementations7 Jul 2022 Dhananjay Ashok, Vineel Nagisetty, Christopher Srinivasa, Vijay Ganesh

We present a novel hybrid algorithm for training Deep Neural Networks that combines the state-of-the-art Gradient Descent (GD) method with a Mixed Integer Linear Programming (MILP) solver, outperforming GD and variants in terms of accuracy, as well as resource and data efficiency for both regression and classification tasks.

Logic Guided Genetic Algorithms

no code implementations21 Oct 2020 Dhananjay Ashok, Joseph Scott, Sebastian Wetzel, Maysum Panju, Vijay Ganesh

Our method, logic-guided genetic algorithm (LGGA), takes as input a set of labelled data points and auxiliary truths (ATs) (mathematical facts known a priori about the unknown function the regressor aims to learn) and outputs a specially generated and curated dataset that can be used with any SR method.
