In this tutorial, we'll learn how to predict tomorrow's S&P 500 index price using historical data. We'll also learn how to avoid common issues that make most stock price models overfit in the real world. We'll start by downloading S&P 500 prices using a package called yfinance. Then, we'll clean up the data with pandas, and get it ready for machine learning. We'll train a random forest model and make predictions using backtesting.

In this course you will build MULTIPLE practical systems using natural language processing, or NLP - the branch of machine learning and data science that deals with text and speech. This course is not part of my deep learning series, so it doesn't contain any hard math - just straight up coding in Python. All the materials for this course are FREE. After a brief discussion about what NLP is and what it can do, we will begin building very useful stuff. The first thing we'll build is a cipher decryption algorithm.

Wikipedia: "In statistics, Bayesian linear regression is an approach to linear regression in which the statistical analysis is undertaken within the context of Bayesian inference. When the regression model has errors that have a normal distribution, and if a particular form of the prior distribution is assumed, explicit results are available for the posterior probability distributions of the model's parameters." The most common interpretation of Bayes' formula in finance is the diachronic interpretation. This mainly states that over time we learn new information about certain variables or parameters of interest, like the mean return of a time series. Here, H stands for an event, the hypothesis, and D represents the data an experiment or the real world might present.

We can see that the top feature for both users is Comedy, which means they like simmilar stuff. What have we done here? Well, we not only described items in terms of the mentioned genres, but we have done the same for each user with the same terms. The meaning for a User1, for example, is that she likes Comedy 0.5 but he likes Action 0.1. Note that if we multiply users embeding matrix with the transpose item embeding matrix we will recreate the user-item interaction matrix. Now, this works well for simple examples with few users and items.

As far back as PCs were created, there has been an exponential development in their capacity and potential to perform different errands. So as to utilize PCs crosswise over assorted working spaces, people have created PC frameworks while expanding their speed, and lessening size regarding time. Man-made reasoning seeks after the flood of building up the PCs or machines to be as shrewd as people themselves. In this article we will scratch the top layer about the ideas of man-made reasoning that will help comprehend related ideas like Artificial Neural Networks, Natural Language Processing, Machine Learning, Deep Learning, Genetic calculations and so forth. Alongside this, we will likewise find out about its usage in Python.

Sentiment analysis is the process of computationally identifying and categorizing opinions expressed in a piece of text, especially in order to determine whether the writer's attitude towards a particular topic, product, etc. is positive, negative, or neutral. In this article, I will show you how to build your own program to determine if an article on a website is positive, negative, or neutral using the Python programming language. If you prefer not to read this post and would like a video representation of it, you can check out the YouTube Video below and the full code on my Github. It goes through everything in this article with a little more detail and will help make it easy for you to start programming your own article sentiment analysis program even if you don't have the programming language Python installed on your computer. Or you can use both as supplementary materials for learning!

If you really want to understand Machine Learning, you need a solid understanding of Statistics (especially Probability), Linear Algebra, and some Calculus. I minored in Math during undergrad, but I definitely needed a refresher. These cheat sheets provide most of what you need to understand the Math behind the most common Machine Learning algorithms.
