ANLY550–Spring, 2017 Programming Assignment 1 Out: February 16, 2017 Due: March 2, 2017 Overview: The purpose of this assignment is to experience some of the problems involved with imple- menting an algorithm (in this case, a minimum spanning tree algorithm) in practice. As an added benefit, we will explore how minimum spanning trees behave in […]
Using Tweets for single stock price prediction Hongshan Chu, Ye Tian, Hongyuan Yuan (By Alphabet) Abstract Stock price, been studied for hundreds of years, is one of the most versatile thus hardly predictable things that is deeply rooted in the modern economy. With the trading frequency reaching sub-second and beyond, more advanced real-time stock price
MLE The usual representation we come across is a probability density function: But what if we know that , but we don’t know ? We can set up a likelihood equation: , and find the value of that maximizes it. P (X = x|!) x1, x2, …, xn ! N(µ, ! 2) µ µ P
