Solutions to Pattern Recognition and Machine Learning by Bishoptommyod@ githubFinished May 2, updated June 27, document contains solutions to selected exercises from the book PatternRecognition and Machine Learning by Christopher M. in 2006, PRML is one of the most popular books in the field of machinelearning. It s clearly written, never boring and exposes the reader to details withoutbeing terse or dry. At the time of writing, the book has close to 36 000 citationsaccording to short chapter summaries are included in this document, they are not in-tended to substitute the book in any way. The summaries will largely be meaninglesswithout the book, which I recommend buying if you re interested in the subject. Thesolutions and notes were typeset in LATEX to facilitate my own Learning hope you find my solutions helpful if you are stuck. Remember to make anattempt at solving the problems yourself before peeking. More likely than not,the solutions can be improved by a reader such as yourself.
The multidimensional Gaussian can be diagonalized by diagonalizing the precision matrix = T1, then exp(xT x) ˘=exp(y Dy), where D= diag(d 1;:::;d D). One limitation is the unimodal nature of the Gaussian, i.e. it has a single peak. Partitioned Gaussians. Let x˘N(xj ; ), where = 1 and x= x a x b = a b = aa ab ba bb: : { Conditional ...
