Active Data Curation Effectively Distills Large-Scale Multimodal Models

CVPR 2025poster

Knowledge distillation (KD) is the de facto standard for compressing large-scale models into smaller ones. Prior works have explored ever more complex KD strategies involving different objective functions, teacher-ensembles, and weight inheritance. In this work we explore an alternative, yet simple…

LayerLock: Non-collapsing Representation Learning with Progressive Freezing

ICCV 2025poster

We introduce LayerLock, a simple yet effective approach for self-supervised visual representation learning, that gradually transitions throughout training from predicting shallow features to deeper ones through progressive layer freezing. First, we make the observation that during training of video…

Data curation via joint example selection further accelerates multimodal learning

NeurIPS 2024spotlight

Data curation is an essential component of large-scale pretraining. In this work, we demonstrate that jointly prioritizing batches of data is more effective for learning than selecting examples independently. Multimodal contrastive objectives expose the dependencies between data and thus naturally y…

Self-supervised video pretraining yields robust and more human-aligned visual representations

NeurIPS 2023poster

Humans learn powerful representations of objects and scenes by observing how they evolve over time. Yet, outside of specific tasks that require explicit temporal understanding, static image pretraining remains the dominant paradigm for learning visual foundation models. We question this mismatch, an…

Towards In-context Scene Understanding

NeurIPS 2023spotlight

In-context learning––the ability to configure a model's behavior with different prompts––has revolutionized the field of natural language processing, alleviating the need for task-specific models and paving the way for generalist models capable of assisting with any query. Computer vision, in contra…

Neural Networks for Efficient Bayesian Decoding of Natural Images from Retinal Neurons

NeurIPS 2017poster

Decoding sensory stimuli from neural signals can be used to reveal how we sense our physical environment, and is valuable for the design of brain-machine interfaces. However, existing linear techniques for neural decoding may not fully reveal or exploit the fidelity of the neural signal. Here we d…
