Chapter 9 of Theoretical Neuroscience. Assumptions on noise in linear regression allow us to estimate the prediction variance due to the noise at any point.. Prediction variance is usually large when you are far from a data point.. We distinguish between interpolation, when we are in the convex hull of the data points, and extrapolation where we are outside.. CS 3220. Fall 2014. Hadi Esmaeilzadeh. hadi@cc.gatech.edu. .

Each type of feature reduces the error rate over the baseline.. SRF and INF features appear to be more predictive than SIF features..
