A Closer Look at Multimodal Representation Collapse

ICML 2025spotlight

We aim to develop a fundamental understanding of modality collapse, a recently observed empirical phenomenon wherein models trained for multimodal fusion tend to rely only on a subset of the modalities, ignoring the rest. We show that modality collapse happens when noisy features from one modality a…

SEBRA : Debiasing through Self-Guided Bias Ranking

ICLR 2025poster

Ranking samples by fine-grained estimates of spuriosity (the degree to which spurious cues are present) has recently been shown to significantly benefit bias mitigation, over the traditional binary biased-vs-unbiased partitioning of train sets. However, this spuriousity ranking comes with the requir…

DeNetDM: Debiasing by Network Depth Modulation

NeurIPS 2024poster

Neural networks trained on biased datasets tend to inadvertently learn spurious correlations, hindering generalization. We formally prove that (1) samples that exhibit spurious correlations lie on a lower rank manifold relative to the ones that do not; and (2) the depth of a network acts as an impli…

Learning Conditional Invariances through Non-Commutativity

ICLR 2024poster

Invariance learning algorithms that conditionally filter out domain-specific random variables as distractors, do so based only on the data semantics, and not the target domain under evaluation. We show that a provably optimal and sample-efficient way of learning conditional invariances is by relaxin…

Transitivity Recovering Decompositions: Interpretable and Robust Fine-Grained Relationships

NeurIPS 2023poster

Recent advances in fine-grained representation learning leverage local-to-global (emergent) relationships for achieving state-of-the-art results. The relational representations relied upon by such methods, however, are abstract. We aim to deconstruct this abstraction by expressing them as interpreta…

Relational Proxies: Emergent Relationships as Fine-Grained Discriminators

NeurIPS 2022accept

Fine-grained categories that largely share the same set of parts cannot be discriminated based on part information alone, as they mostly differ in the way the local parts relate to the overall global structure of the object. We propose Relational Proxies, a novel approach that leverages the relation…
