Context-Aware Multimodal Pretraining

no code implementations22 Nov 2024 Karsten Roth, Zeynep Akata, Dima Damen, Ivana Balažević, Olivier J. Hénaff

Large-scale multimodal representation learning successfully optimizes for zero-shot transfer at test time.

Contrastive Learning Representation Learning +1

Reflecting on the State of Rehearsal-free Continual Learning with Pretrained Models

no code implementations13 Jun 2024 Lukas Thede, Karsten Roth, Olivier J. Hénaff, Matthias Bethge, Zeynep Akata

(2) Indeed, we show how most often, P-RFCL techniques can be matched by a simple and lightweight PEFT baseline.

Layerwise complexity-matched learning yields an improved model of cortical area V2

no code implementations18 Dec 2023 Nikhil Parthasarathy, Olivier J. Hénaff, Eero P. Simoncelli

Finally, when the two-stage model is used as a fixed front-end for a deep network trained to perform object recognition, the resultant model (LCL-V2Net) is significantly better than standard end-to-end self-supervised, supervised, and adversarially-trained models in terms of generalization to out-of-distribution tasks and alignment with human behavior.

Object Recognition

Three ways to improve feature alignment for open vocabulary detection

no code implementations23 Mar 2023 Relja Arandjelović, Alex Andonian, Arthur Mensch, Olivier J. Hénaff, Jean-Baptiste Alayrac, Andrew Zisserman

The core problem in zero-shot open vocabulary detection is how to align visual and text features, so that the detector performs well on unseen classes.

Language Modelling

Geodesics of learned representations

no code implementations19 Nov 2015 Olivier J. Hénaff, Eero P. Simoncelli

We develop a new method for visualizing and refining the invariances of learned representations.

Image Classification Translation

The local low-dimensionality of natural images

no code implementations20 Dec 2014 Olivier J. Hénaff, Johannes Ballé, Neil C. Rabinowitz, Eero P. Simoncelli

We develop a new statistical model for photographic images, in which the local responses of a bank of linear filters are described as jointly Gaussian, with zero mean and a covariance that varies slowly over spatial position.
