Neural scaling laws for phenotypic drug discovery

no code implementations28 Sep 2023 Drew Linsley, John Griffin, Jason Parker Brown, Adam N Roose, Michael Frank, Peter Linsley, Steven Finkbeiner, Jeremy Linsley

Recent breakthroughs by deep neural networks (DNNs) in natural language processing (NLP) and computer vision have been driven by a scale-up of models and data rather than the discovery of novel computing paradigms.

Drug Discovery

Fixing the problems of deep neural networks will require better training data and learning algorithms

no code implementations26 Sep 2023 Drew Linsley, Thomas Serre

Bowers and colleagues argue that DNNs are poor models of biological vision because they often learn to rival human accuracy by relying on strategies that differ markedly from those of humans.

Unlocking Feature Visualization for Deeper Networks with MAgnitude Constrained Optimization

1 code implementation11 Jun 2023 Thomas Fel, Thibaut Boissin, Victor Boutin, Agustin Picard, Paul Novello, Julien Colin, Drew Linsley, Tom Rousseau, Rémi Cadène, Laurent Gardes, Thomas Serre

However, its widespread adoption has been limited due to a reliance on tricks to generate interpretable images, and corresponding challenges in scaling it to deeper neural networks.

Adversarial alignment: Breaking the trade-off between the strength of an attack and its relevance to human perception

no code implementations5 Jun 2023 Drew Linsley, Pinyuan Feng, Thibaut Boissin, Alekh Karkada Ashok, Thomas Fel, Stephanie Olaiya, Thomas Serre

Harmonized DNNs achieve the best of both worlds and experience attacks that are detectable and affect features that humans find diagnostic for recognition, meaning that attacks on these models are more likely to be rendered ineffective by inducing similar effects on human perception.

Harmonizing the object recognition strategies of deep neural networks with humans

3 code implementations8 Nov 2022 Thomas Fel, Ivan Felipe, Drew Linsley, Thomas Serre

Across 84 different DNNs trained on ImageNet and three independent datasets measuring the where and the how of human visual strategies for object recognition on those images, we find a systematic trade-off between DNN categorization accuracy and alignment with human visual strategies for object recognition.

Object Object Recognition

The Challenge of Appearance-Free Object Tracking with Feedforward Neural Networks

no code implementations30 Sep 2021 Girik Malik, Drew Linsley, Thomas Serre, Ennio Mingolla

Here, we introduce $\textit{PathTracker}$, a visual challenge inspired by cognitive psychology, which tests the ability of observers to learn to track objects solely by their motion.

Understanding the computational demands underlying visual reasoning

no code implementations8 Aug 2021 Mohit Vaishnav, Remi Cadene, Andrea Alamia, Drew Linsley, Rufin VanRullen, Thomas Serre

Our analysis reveals a novel taxonomy of visual reasoning tasks, which can be primarily explained by both the type of relations (same-different vs. spatial-relation judgments) and the number of relations used to compose the underlying rules.

Tracking Without Re-recognition in Humans and Machines

no code implementations NeurIPS 2021 Drew Linsley, Girik Malik, Junkyung Kim, Lakshmi N Govindarajan, Ennio Mingolla, Thomas Serre

For this, we introduce PathTracker, a synthetic visual challenge that asks human observers and machines to track a target object in the midst of identical-looking "distractor" objects.

Recurrent neural circuits for contour detection

no code implementations ICLR 2020 Drew Linsley, Junkyung Kim, Alekh Ashok, Thomas Serre

We introduce a deep recurrent neural network architecture that approximates visual cortical circuits.

Contour Detection

Stable and expressive recurrent vision models

1 code implementation NeurIPS 2020 Drew Linsley, Alekh Karkada Ashok, Lakshmi Narasimhan Govindarajan, Rex Liu, Thomas Serre

We posit that the effectiveness of recurrent vision models is bottlenecked by the standard algorithm used for training them, "back-propagation through time" (BPTT), which has O(N) memory-complexity for training an N step model.

Panoptic Segmentation

Disentangling neural mechanisms for perceptual grouping

no code implementations ICLR 2020 Junkyung Kim, Drew Linsley, Kalpit Thakkar, Thomas Serre

Forming perceptual groups and individuating objects in visual scenes is an essential step towards visual intelligence.

Learning what and where to attend with humans in the loop

no code implementations ICLR 2019 Drew Linsley, Dan Shiebler, Sven Eberhardt, Thomas Serre

Most recent gains in visual recognition have originated from the inclusion of attention mechanisms in deep convolutional networks (DCNs).

Learning what and where to attend

1 code implementation22 May 2018 Drew Linsley, Dan Shiebler, Sven Eberhardt, Thomas Serre

Most recent gains in visual recognition have originated from the inclusion of attention mechanisms in deep convolutional networks (DCNs).

Image Categorization Object Recognition

Learning long-range spatial dependencies with horizontal gated-recurrent units

1 code implementation NeurIPS 2018 Drew Linsley, Junkyung Kim, Vijay Veerabadran, Thomas Serre

As a prime example, convolutional neural networks, a type of feedforward neural networks, are now approaching -- and sometimes even surpassing -- human accuracy on a variety of visual recognition tasks.

Contour Detection

What are the visual features underlying human versus machine vision?

no code implementations10 Jan 2017 Drew Linsley, Sven Eberhardt, Tarun Sharma, Pankaj Gupta, Thomas Serre

Our study demonstrates that the narrowing gap between the object recognition accuracy of human observers and DCNs obscures distinct visual strategies used by each to achieve this performance.
