“Theorists have long postulated for decades that the brain might be using unsupervised learning,” first author and research scientist at HHMI, Lin Zhong, told IFLScience. “Humans definitely employ ...

Isolation Forest detects anomalies by isolating observations. It builds binary trees (called iTrees) by recursively ...

(3) They adaptively learn the graph in the original or embedding space. Thus, the learned graph cannot characterize the data’s cluster structure. To solve these limitations, we present a novel ...

Unsupervised feature selection is challenging in machine learning, pattern recognition, and data mining. The crucial difficulty is to learn a moderate subspace that preserves the intrinsic structure ...
