| | 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...

| 1. Low-rank approximation of matrices Let $latex {A}&fg=000000$ be an arbitrary $latex {n \times m}&fg=000000$ matrix. We assume $latex {n \leq m}&fg=000000$. We consider the problem of approximating $latex {A}&fg=000000$ by a low-rank matrix. For example, we could seek to find a rank $latex {s}&fg=000000$ matrix $latex {B}&fg=000000$ minimizing $latex { \lVert A - B...
