DenseFormer: Enhancing Information Flow in Transformers via Depth Weighted Averaging

1 code implementation4 Feb 2024 Matteo Pagliardini, Amirkeivan Mohtashami, Francois Fleuret, Martin Jaggi

The transformer architecture by Vaswani et al. (2017) is now ubiquitous across application domains, from natural language processing to speech processing and image understanding.

DeepEMD: A Transformer-based Fast Estimation of the Earth Mover's Distance

1 code implementation16 Nov 2023 Atul Kumar Sinha, Francois Fleuret

We propose an attention-based model to compute an accurate approximation of the EMD that can be used as a training loss for generative models.

SequeL: A Continual Learning Library in PyTorch and JAX

1 code implementation21 Apr 2023 Nikolaos Dimitriadis, Francois Fleuret, Pascal Frossard

Continual Learning is an important and challenging problem in machine learning, where models must adapt to a continuous stream of new data without forgetting previously acquired knowledge.

Efficiently Training Low-Curvature Neural Networks

2 code implementations14 Jun 2022 Suraj Srinivas, Kyle Matoba, Himabindu Lakkaraju, Francois Fleuret

To achieve this, we minimize a data-independent upper bound on the curvature of a neural network, which decomposes overall curvature in terms of curvatures and slopes of its constituent layers.

HyperMixer: An MLP-based Low Cost Alternative to Transformers

3 code implementations7 Mar 2022 Florian Mai, Arnaud Pannatier, Fabio Fehr, Haolin Chen, Francois Marelli, Francois Fleuret, James Henderson

We find that existing architectures such as MLPMixer, which achieves token mixing through a static MLP applied to each feature independently, are too detached from the inductive biases required for natural language understanding.

DepthInSpace: Exploitation and Fusion of Multiple Video Frames for Structured-Light Depth Estimation

no code implementations ICCV 2021 Mohammad Mahdi Johari, Camilla Carta, Francois Fleuret

We first propose to use estimated optical flow from ambient information of multiple video frames as a complementary guide for training a single-frame depth estimation network, helping to preserve edges and reduce over-smoothing issues.

Rethinking the Role of Gradient-Based Attribution Methods for Model Interpretability

1 code implementation ICLR 2021 Suraj Srinivas, Francois Fleuret

This leads us to hypothesize that the highly structured and explanatory nature of input-gradients may be due to the alignment of this class-conditional model $p_{\theta}(x \mid y)$ with that of the ground truth data distribution $p_{\text{data}} (x \mid y)$.

Real-Time Segmentation Networks should be Latency Aware

no code implementations6 Apr 2020 Evann Courdier, Francois Fleuret

We propose a change of objective in the segmentation task, and its associated metric that encapsulates this missing information in the following way: We propose to predict the future output segmentation map that will match the future input frame at the time when the network finishes the processing.

On the Tunability of Optimizers in Deep Learning

no code implementations25 Sep 2019 Prabhu Teja S*, Florian Mai*, Thijs Vogels, Martin Jaggi, Francois Fleuret

There is no consensus yet on the question whether adaptive gradient methods like Adam are easier to use than non-adaptive optimization methods like SGD.

Full-Gradient Representation for Neural Network Visualization

2 code implementations NeurIPS 2019 Suraj Srinivas, Francois Fleuret

Our experiments reveal that our method explains model behaviour correctly, and more comprehensively than other methods in the literature.

Knowledge Transfer with Jacobian Matching

no code implementations ICML 2018 Suraj Srinivas, Francois Fleuret

We then rely on this analysis to apply Jacobian matching to transfer learning by establishing equivalence of a recent transfer learning procedure to distillation.

Non-Markovian Globally Consistent Multi-Object Tracking

no code implementations ICCV 2017 Andrii Maksai, Xinchao Wang, Francois Fleuret, Pascal Fua

Many state-of-the-art approaches to multi-object tracking rely on detecting them in each frame independently, grouping detections into short but reliable trajectory segments, and then further grouping them into full trajectories.

Kronecker Recurrent Units

no code implementations ICML 2018 Cijo Jose, Moustpaha Cisse, Francois Fleuret

It overcomes the ill-conditioning of the recurrent matrix by enforcing soft unitary constraints on the factors.

Semi-supervised learning of deep metrics for stereo reconstruction

no code implementations3 Dec 2016 Stepan Tulyakov, Anton Ivanov, Francois Fleuret

The main contribution of our work is a new semi-supervised method for learning deep metrics from unlabeled stereo images, given coarse information about the scenes and the optical system.

Globally Consistent Multi-People Tracking using Motion Patterns

1 code implementation2 Dec 2016 Andrii Maksai, Xinchao Wang, Francois Fleuret, Pascal Fua

Many state-of-the-art approaches to people tracking rely on detecting them in each frame independently, grouping detections into short but reliable trajectory segments, and then further grouping them into full trajectories.
