Visualizing Data using t-SNE
VISUALIZING DATA USING T-SNE 2. Stochastic Neighbor Embedding Stochastic Neighbor Embedding (SNE) starts by converting the high-dimensional Euclidean dis-tances between datapoints into conditional probabilities that represent similarities.1 The similarity of datapoint xj to datapoint xi is the conditional probability, pjji, that xi would pick xj as its neighbor

A Tutorial on Conformal Prediction
jmlr.csail.mit.edutically independent. This allows us to interpret “being right 95% of the time” in an unusually direct way. In §2.1, we illustrate this point with a well-worn example, normally distributed random vari-ables. In §2.2, we contrast confidence with full-fledged …
Random Search for Hyper-Parameter Optimization
jmlr.csail.mit.eduRANDOM SEARCH FOR HYPER-PARAMETER OPTIMIZATION search is used to identify regions in Λthat are promising and to develop the intuition necessary to choose the sets L(k).A major drawback of manual search is the difficulty in reproducing results.

An Introduction to Variable and Feature Selection
jmlr.csail.mit.eduoutside of the scope of machine learning, so we focus here on building predictors. We consider in this section ranking criteria defined for individual variables, independe ntly of the context of others. Correlation methods belong to that category. We also limit ourselves to supervised learning criteria.
