| | | | For an $latex n\times n$ matrix $latex \notag A = \begin{bmatrix} A_{11} & A_{12} \\ A_{21} & A_{22} \end{bmatrix} \qquad (1) $ with nonsingular $latex (1,1)$ block $LATEX A_{11}$ the Schur complement is $LATEX A_{22} - A_{21}A_{11}^{-1}A_{12}$. It is denoted by $LATEX A/A_{11}$. The block with respect to which the Schur complement is taken need... | |

| | | | I've just finished reading 'Turing's Cathedral,' an absolutely fascinating book on early computing. The book focuses almost entirely on John von Neumann's 'Electronic Computer Project' carried out at the Institute of Advanced Study in the 40's and 50's. In fact, Turing makes only occasional and brief appearances in the book: it's almost entirely a portrait... | |

| | | | Let me tell you about a mistake I made recently. Some months ago, I made a few calculations which seemed promising, and I thought they could lead to some new results. When I showed the calculations to my supervisor, he was skeptical, and rightly so. Our project involved some fairly abstract concepts in the theory... | |

| | Below, are the predicted NBA team wins for the 2024-2025 seasons (within a margin of error of +/- 5 wins) based on our novel ML algorithm to predict team wins. We collected over 20 years of NBA team data and applied advanced nonparametric, nonlinear models to uncover the relationship between various performance indicators and a... |
