DREAM: Dynamic Resolution Assignment For Multimodal Multi-agent Debate

Multi-agent debate (MAD) has emerged as an effective paradigm to improve the reasoning capabilities of large language models (LLMs) and is increasingly being extended to multimodal settings. However, existing multimodal MAD frameworks typically expose agents to the same fixed visual input, ignoring substantial variatio...

Predicting Symptoms of Amotivation and Anhedonia among University Students with a Novel Oversampling Method

A novel and effective oversampling method that leverages a predictive model to generate nominal variables, rather than interpolating them and is significantly better than existing oversampling approaches in predicting elevated symptoms of amotivation and anhedonia.

A Statistical Approach to Estimating Sample Size of Machine Learning Models

Sample size determination for machine learning (ML) prediction models is challenging because conventional power analysis typically requires the predictor-outcome relationship and effect structure to be specified a priori. Nonlinear ML models learn complex prediction surfaces that do not admit straightforward analytical...
