Exemplar-Free Continual Transformer with Convolutions

open access: yes2023 IEEE/CVF International Conference on Computer Vision (ICCV), 2023
Continual Learning (CL) involves training a machine learning model in a sequential manner to learn new information while retaining previously learned tasks without the presence of previous training data. Although there has been significant interest in CL, most recent CL approaches in computer vision have focused on convolutional architectures only ...

The atoms of operator-valued free convolutions

open access: yes, 2021
International audienceSuppose that $X_1$ and $X_2$ are two selfadjoint random variables that are freely independent over an operator algebra B. We describe the possible operator atoms of the distribution of $X_1+X_2$ and, using linearization, we ...

Online knowledge distillation network for single image dehazing

open access: yesScientific Reports, 2022
Single image dehazing, as a key prerequisite of high-level computer vision tasks, catches more and more attentions. Traditional model-based methods recover haze-free images via atmospheric scattering model, which achieve favorable dehazing effect but ...

Finite free convolutions via Weingarten calculus

open access: yes, 2020
We consider the three finite free convolutions for polynomials studied in a recent paper by Marcus, Spielman, and Srivastava. Each can be described either by direct explicit formulae or in terms of operations on randomly rotated matrices.

Comparison Between Frame-Constrained Fix-Pixel-Value and Frame-Free Spiking-Dynamic-Pixel ConvNets for Visual Processing

open access: yesFrontiers in Neuroscience, 2012
Most scene segmentation and categorization architectures for the extraction of features in images and patches make exhaustive use of 2D convolution operations for template matching, template search and denoising.
