Introduction to Ordinary Least Squares Introduction to Ordinary Least Squares
In empirical finance and many other domains, linear regression and the closely related linear prediction theory are commonly used statistical methods. Because of the wide range of applications, basic linear regression courses normally concentrate on the mathematically simplest scenario, which can be used in a variety of other applications.

Skewness and Kurtosis Skewness and Kurtosis
Statistics is a discipline of applied mathematics that deals with the gathering, describing, analysing, and inferring conclusions from numerical data. Differential and integral calculus, linear algebra, and probability theory are all used substantially in statistics' mathematical theories.

Install RPM Files on Ubuntu Install RPM Files on Ubuntu
On Ubuntu, I will show you how to instal RPM packages. The design of Debian-based systems like Ubuntu and RedHat-based systems like CentOS is quite similar. There are, however, a few minor differences. For example, RPM files are used to represent software packages on RedHat-based systems, while DEB files are used on Debian-based systems. An RPM package can be installed in one of two ways, by converting the RPM file to a DEB file or by installing the RPM file directly. Both approaches are easy, but depending on the package being installed, installing RPM packages on a Debian-based system can cause problems.

Busuanzi Unable to Display the Number of Visitors Busuanzi Unable to Display the Number of Visitors
When adding statistics to the number of people and visits to the Hexo blog, according to the standard process of writing, pushing the number of people and visits after running found that the number of people simply do not load. Looking through the information found that the reason, busuanzi because in 2018/10/12 its domain name expired, so the number of people can not be displayed.

Detect Covariate Shift Detect Covariate Shift
A supervised machine learning model has two phases, training and testing. When these models are learned, validated, and tested, the test and train data points are normally presumed to have the same distribution. In the real world, however, the training and test datasets rarely follow the same distribution.

Predicting Stock Price using LSTM Predicting Stock Price using LSTM
This article tends to build a model that predicts stock price in the best way possible. This is an example of how you can use Long Short-Term Memory (LSTM) Neural Network on some real-world time series data with PyTorch. Hopefully, there are much better models that forecast the price of the stock.

Harry Potter Movies Saga Analysis Harry Potter Movies Saga Analysis
In this article, a sentiment analysis is conducted through the lens of Harry Potter. I am a self-confessed Harry Potter devotee. I've read the books multiple times and watched the films more times than I can count. The lines of each characters in the movies are rich in emotionally charged experiences that the reader can viscerally feel. Can a computer capture that feeling? Let's check it out!

Sentiment Analysis for Japanese Customer Reviews Sentiment Analysis for Japanese Customer Reviews
The development of elec-tronic business is accelerated by the popularity of the internet. Millions of people buy products and post their reviews online. Public opinion analysis can be used with these reviews. Customers can make better decisions after reading other people's product reviews. There is a pressing need for building the system which can perform the sentiment classification job. In this article, I'll try to build a sentiment anaylsis model for Japanese customer reviews.

Softmax and Cross-Entropy Softmax and Cross-Entropy
I'm trying to implement neural network from scratch in Python recently. Considering to solve multi-class classification problem using neural network, I try to create a simple neural network. The most important thing in neural network is backpropagation. Backpropagation is an algorithm for supervised learning of artificial neural networks using gradient descent. I want to find the derivation of cross-entropy loss function with softmax activation function, so this article will record the formula I calculated. As for the rest, I will discuss it in the future.

Viterbi Algorithm for HMM Decoding Viterbi Algorithm for HMM Decoding
Viterbi Algorithm is usually used to find the most likely sequence in HMM. It is now also commonly used in speech recognition, speech synthesis, diarization, keyword spotting, computational linguistics, and bioinformatics. This semester, in the course "Speech Technology", the acoustic signal is treated as the observed sequence of events, and a string of text is considered to be the hidden cause of the acoustic signal in speech recognition task. The Viterbi algorithm finds the most likely string of text given the acoustic signal.

Develop Strategy for Tic-Tac-Toe Develop Strategy for Tic-Tac-Toe
Tic-tac-toe is a paper-and-pencil game for two players, X and O, who take turns marking the spaces in a 3×3 grid. The player who succeeds in placing three of their marks in a diagonal, horizontal, or vertical row is the winner. It is a solved game with a forced draw assuming best play from both players. In this article, I want to discuss whether there's a must-win strategy for this game.
