WebRETRIEVE selects the coreset by solving a mixed discrete-continuous bi-level optimization problem such that the selected coreset minimizes the labeled set loss. We use a one-step gradient approximation and show that the discrete optimization problem is approximately submodular, thereby enabling simple greedy algorithms to obtain the coreset. WebThis work proposes Gradient Coreset Replay (GCR), a novel strategy for replay buffer selection and update using a carefully designed optimization criterion, and demonstrates the value of supervised contrastive loss for continual learning, which yields a cumulative gain of up to 5% accuracy when combined with the subset selection strategy.

Webtrom methods [2, 32], and Bayesian inference [6]. Coreset construction methods traditionally perform importance sampling with respect to sensitivity score, defined as the importance of the point with respect to the objective func-tion we wish to minimize, to provide high-probability solutions [16, 30, 10]. Greedy algorithms, which are spe- WebJul 29, 2024 · Submodular functions naturally measure the diversity and information, thus can be a powerful tool for coreset selection by maximizing them. Many functions obey …
WebWe devise a coreset selection method based on the idea of gradient matching: the gradients induced by the coreset should match, as closely as possible, those induced ... To approximate solutions to problem (3) we use greedy selection with matching pursuit [Mallat and Zhang, 1993]. Assume we currently have a coreset Iˆ[N] with corresponding weights Web2 Review of Coreset Selection Methods In this section, we rst formulate the problem of coreset selection. Then, brief surveys of methods and applications of coreset selection are provided respec-tively. 2.1 Problem Statement In a learning task, we are given a large training set T= f(x i;y i)g jTj i=1, where x i 2Xis the input, y i 2Yis the ...
