Material Detail

This video was recorded at Machine Learning Summer School (MLSS), Canberra 2005. Dedicated machine learning procedures have already become an integral part of modern genomics and proteomics. However, these very high dimensional and low learning sample tasks often stretch these procedures well beyond natural boundaries of their applicability. A few such challenges will be a subject of this series of lectures. We will start with a brief overview of classification of genomics (microarray) data. In particular we shall discuss, in some detail, examples of applications to cancer genomics and proteomics. Then we concentrate on a phenomenon of anti-learning, a case of supervised classification where standard supervised learning techniques systematically produce classifiers perfect on learning sample but with independent test error rates higher than that of the default (random) classification rule. The examples of natural and synthetic anti-learning data will be given and analysed from the stand point of implications to practical supervised and unsupervised classification. A series of practical tutorials will be organized in parallel. Participants will be exposed to classification of microarray data including first-hand experience with anti-learning.
