Learning Objectives By the end of this section, you will be able to: Use summation notation. Use the formula for the sum of the firstnnterms of an arithmetic series. Use the formula for the sum of the firstnnterms of a geometric series. Use the formula for the sum of an infi...
This survey is intended to inform non-expert readers about the field of recommender systems, particularly collaborative filtering, through the lens of the impactful Netflix Prize competition. Readers will quickly be brought up to speed on pivotal recommender systems advances through the Netflix Prize,...
The bilateral z transform of the discrete-time signal is defined to be (7.1)where is a complex variable. Since signals are typically defined to begin (become nonzero) at time , and since filters are often assumed to be causal,7.1 the lower summation limit given above may be written as ...

Readers will need a degree of mathematical sophistication and general tools such as sets, functions, and summation notation. No single college course is a prerequisite, but most students will do better with some prior college mathematics. This thorough introduction to linear programming and game ...
, and the summation is over all possible values of ; the formula for the posterior probability mass function of is the same as in the continuous case: Proportionality We now take a moment to explain some simple algebra that is extremely important in Bayesian inference. ...
to also be close to 1. So as hΘ(xi)hΘ(xi) approaches 1, the log(hΘ(xi))log(hΘ(xi)) becomes very close to 0. Since the log of a value between 0 and 1 is negative, we must take the negative of the entire summation to compute the cost. The parameters are randomly initial...
