This repo is a companion to a YouTube tutorial by Siraj Raval, and it demonstrates how to use deep learning to predict stock market prices. Specifically, it tries to forecast the closing price of the S&P 500 stock index based on historical price data. The goal is to give beginners a hands-on starting point for applying machine learning to financial markets. The project uses a specific type of artificial intelligence called an LSTM neural network. At a high level, this kind of network is designed to find patterns in sequences of data over time, which makes it a popular choice for tasks like weather forecasting or stock price prediction. You feed the network a bunch of past prices, and it attempts to learn the underlying trends to guess what the next price will be. The audience here is clearly newcomers to deep learning. You run the project through Jupyter Notebook, a tool that lets you read explanations and run code step-by-step in a web browser. To actually use it, you need to install two underlying machine learning tools: Keras and TensorFlow. These are industry standards for building AI, but they do require some setup on your computer. The original tutorial also included a coding challenge for viewers to expand on the demo by adding two extra data sources to predict Google's stock price, though that was tied to a deadline back in 2017. The code itself is a wrapper built on top of another open-source project, meaning it simplifies someone else's more complex work to make it more approachable for beginners. It is worth noting that this is a basic educational demo, not a guaranteed money-making tool. Stock markets are incredibly complex and noisy, so predicting prices from historical data alone is notoriously difficult. The real value is learning how these predictive models function, not executing live financial trades.
