Theoretical Computer Science

Usually, computer science seems like a practical field that involves studying, building, and working closely with computers. However, a subclass of this discipline also centers on the mathematical factors of the same. This is called theoretical computer science, and its focal point differentiates it from other branches of computer science: the rigorous mathematical approach it takes. This discipline falls under the umbrella of discrete mathematics, which is the study of countable or discontinuous mathematical structures.

Question

Suppose that there is a color column (feature) in a data frame with values in ("Blue", "Green", "Black",

Consider that you have performed Principal Component Analysis of a centered and unscaled data set, that is, the variance-covariance matrix to be analysed is not equal to the correlation matrix. To do the PCA for the same set, but now centered and scaled, Select one: a. reuse the eigenvalues, with the only change is to rescale them to add to the number of components. The eigenvectors are the same. O b. it is not possible to reuse eigenvalues nor eigenvectors. in some selected instances we can reuse eigenvalues and eigenvectors of the analysis of centered and unscaled data. C.
"When conducting a binary regression with a skewed predictor, it is often easiest to assess the need for x and log(x) by including them both in the model so that their relative contributions can be assessed directly." Show that indeed the log odds are a function of x and log(x) for the gamma distribution.

In contrast to k-nearest-neighbor, local regression methods weight the influence of an observation to the estimation of the response based on its distance from the point of interest. The weights usually take the form 1 Xi – x0 Wi h h for a certain kernel w(·). Discuss the role of h and relate it to the concept of bias-variance trade- off. Briefly explain why the concept of bias-variance trade-off is important for prediction.
