D. LeJeune, H. Javadi, R. G. Baraniuk, "The Implicit Regularization of Ordinary Least Squares Ensembles," 免费的pcvpn, 10 October 2023.

Ensemble methods that average over a collection of independent predictors that are each limited to a subsampling of both the examples and features of the training data command a significant presence in machine learning, such as the ever-popular random forest, yet the
nature of the subsampling effect, particularly of the features, is not well understood.  We study the case of an ensemble of linear predictors, where each individual predictor is fit using ordinary least squares on a random submatrix of the data matrix. We show that, under standard Gaussianity assumptions, when the number of features selected for each predictor is optimally tuned, the asymptotic risk of a large ensemble is equal to the asymptotic ridge regression risk, which is known to be optimal among linear predictors in this setting. In addition to eliciting this implicit regularization that results from subsampling, we also connect this ensemble to the dropout technique used in training deep (neural) networks, another strategy that has been shown to have a ridge-like regularizing effect.

Above: Example (rows) and feature (columns) subsampling of the training data X used in the ordinary least squares fit for one member of the ensemble. The i-th member of the ensemble is only allowed to predict using its subset of the features (green). It must learn its parameters by performing ordinary least squares using the subsampled examples of (red) and the subsampled examples (rows) and features (columns) of X (blue, crosshatched).

From an article in Campus Technology:  This year, 56% of all colleges and universities in the United States are using free textbooks from OpenStax in at least one course. That equates to 5,900-plus institutions and nearly 3 million students.

OpenStax provides textbooks for 36 college and Advanced Placement courses. Students can access the materials for free digitally (via browser, downloadable PDF or recently introduced OpenStax + SE mobile app), or pay for a low-cost print version. Overall, students are saving more than $200 million on their textbooks in 2023, and have saved a total of $830 million since OpenStax launched in 2012.

Future plans for the publisher include the rollout of Rover by OpenStax, an online math homework tool designed to give students step-by-step feedback on their work. OpenStax also plans to continue its research initiatives on digital learning, using cognitive science-based approaches and the power of machine learning to improve how students learn.

Writes Chris Taylor from Reuters in Moneysaving 101: Four Ways to Cut College Textbook Costs, "While sky-high U.S. college tuition might be the headline number, here is a sneaky little figure that might surprise you: the cost of textbooks."  See what OpenStax is doing about the crisis here.
