WebFeb 1, 2024 · TL;DR: We propose, analyze, and evaluate a machine teaching approach to data subset selection. Abstract: We study the problem of data subset selection: given a fully labeled dataset and a training procedure, select a subset such that training on that subset yields approximately the same test performance as training on the full dataset. WebApr 11, 2024 · The main difference between AI and machine learning is that AI encompasses a broader range of technologies, while machine learning focuses on data-driven algorithms that improve through experience. Both have found applications in numerous fields, including healthcare, retail, and higher education, revolutionizing how …
WebSubset selection to increase accuracy. Recently, Chang et al. (2024) proposed to choose data points whose predictions have changed most over the previous epochs as a lightweight estimate of uncertainty. From the machine teaching literature, Fan et al. (2024) demonstrated that data selection can be learned through reinforcement learning. WebJun 9, 2024 · 21. In principle, if the best subset can be found, it is indeed better than the LASSO, in terms of (1) selecting the variables that actually contribute to the fit, (2) not selecting the variables that do not contribute to the fit, (3) prediction accuracy and (4) producing essentially unbiased estimates for the selected variables.
