#книга Свежая книга "Random Matrix Methods for Machine Learning" поможет понять, зачем в машинном обучении нужны функции комплексного переменного, интегралы по контуру, спектральная теория, комбинаторика и т.п. Есть следующие разделы - Random Matrix Theory - Statistical Inference in Linear Models - Kernel Methods - Large Neural Networks - Large-Dimensional Convex Optimization - Community Detection on Graphs - Universality and Real Data Например, в первом изучается спектр матрицы XX^T, которая много где возникает (в методе главных компонент, теории ядер и т.п.) А в четвёртом есть интересные результаты про т.н. двойной спуск.

Pinterest (PINS) closed at $71.75 in the latest trading session, marking a -0.18% move from the prior day. This change lagged the S&P 500's daily gain of 0.1%. Meanwhile, the Dow gained 0.9%, and the Nasdaq, a tech-heavy index, lost 0.59%.
Heading into today, shares of the digital pinboard and shopping tool company had lost 17.41% over the past month, lagging the Computer and Technology sector's loss of 5.38% and the S&P 500's gain of 0.71% in that time.
Investors will be hoping for strength from PINS as it approaches its next earnings release. The company is expected to report EPS of $0.07, up 170% from the prior-year quarter. Our most recent consensus estimate is calling for quarterly revenue of $467.87 million, up 72.05% from the year-ago period.
However, analysts are positive on the stock now. “We have seen a huge downside movement in the stock due to the central electricity regulatory commission’s (CERC) order that seems to be negative from 2014-15 onwards but we cannot take a linear negative view on the stock and further downside movement on the stock is unlikely. Currently stock is underpriced. Investors can bet on it for a longer horizon," said Vivek Gupta, director research at CapitalVia Global Research.
