Hi, I have done quite a good number of projects on intelligent data analysis using AI methods in MATLAB. There are a couple of stock market prediction projects too based on fuzzy-logic rule based, ANN and RNN.
To just give you an idea, this will need something like a e-phishing system that detects spams based on keywords (analogous to news headlines) and a neural-network that trains on historical data and keywords from news headlines. A conglomeration of these two systems will be the aim of this project. Second, is preparing the database, for keywords and stock prices (opening, closing, etc). The qualitative + quantitative factors will together be trained to the model. One of my previous project used half of this task.
I hope you have got an idea of how to proceed. Message me when you are free, if interested. Thanks and have a nice day.
