Intro to Economic analysis

– Introduction to Economic Analysis is the introductory course of the theory concentration major in Economics. It is intended for students who wish to begin their formal study of economic reasoning. Its goal is to develop concepts and analytical tools that economists use to understand general social and economic phenomena. As such it relies on a higher level of abstraction and focuses on the co...

A Study of Web Information Extraction Technology Based on Beautiful Soup

In the context of comparative analysis of common web information retrieval technologies, this article discusses the principles and applications of Beautiful Soup, a vertical information search technology based on DOM tree structure. Supported by actual system examples and centering on the system architecture and core technology, this article discusses how to use Beautiful Soup to conduct deep i...

Intro to generalization; Chernoff method

i=1 `(f(xi), yi)), f̄ := ”argminf∈F”R(f), f̄n := ”argminf∈F”R̂(f), f̂ output of optimization algorithm, ḡ := ”argming measurable”R(g). (As usual, argmin has technical issues we are avoiding, hence the quotes.) The goal in a machine learning problem is to make an algorithm that outputs f̂ so that R(f̂)−R(ḡ) is small. We can decompose this error into the following pieces: R(f̂)−R(ḡ) = R(f̂)− R̂(f̂) (4) + R̂...
