First consider pure science. Science is the body of knowledge about the world we live in which has been found by the activity we call research. Note that in considering the nature of science or research we are in no way concerned with the formalisms or techniques we have discussed. These are merely means to an end a set of man-made tools from which we each make our own selections when we do res...

First some context. In supervised learning in general, the goal is to learn or infer an (initially) unknown function f : x 7→ y, from a set of training data in the form of T “input/output” pairs {(xμ, yμ)}μ=1:T . 1 More generally, you try to infer the conditional distribution ρ(y|x) from this training set; the reason is that in general your outputs contains some noise (or stated better, trial-t...

The initial lower rate may have been due to underascertainment, but the recent dramatic fall is statistically sig...
متن کاملFactor Analysis and Aic
The information criterion AIC was introduced to extend the method of maximum likelihood to the multimodel situation. It was obtained by relating the successful experience of the order determination of an autoregressive model to the determination of the number of factors in the maximum likelihood factor analysis. The use of the AIC criterion in the factor analysis is particularly interesting whe...
