Title: Multimodal Datasets with Controllable Mutual Information
Primary area: datasets and benchmarks
Keywords: Flow Matching, Mutual Information, Directed Acyclic Graphs, Synthetic Data

Abstract: We introduce a framework for generating highly multimodal datasets with explicitly calculable mutual information between modalities. This enables the construction of benchmark datasets that provide a novel testbed for systematic studies of mutual information estimators and multimodal self-supervised learning techniques. Our framework constructs realistic datasets with known mutual information using a flow-based generative model and a structured causal framework for generating correlated latent variables.

TL;DR: We introduce a framework for generating highly multimodal datasets with explicitly calculable mutual information between modalities.
