Are you seriously asking if hedge funds that pay hundreds of thousands of dollars salary to top experts from all kinds of fields have investigated using machine learning?
- tormeh 10y agoObviously someone has, but I want to know the results.
- tomp 10y agoYou can't just "toss a NN to stock market data" and expect good results. There's too little historical data, you can't easily "generate" more data for the network to learn from, making it really easy to overfit. In other fields (e.g. computer vision) a lot of research has been focused on inventing techniques that prevent overfitting, thus enabling "learning" (i.e. generalization of patterns), such as dropout, convolutional neural networks, flipping/rotating images, etc. Very few of these techniques can be applied generally.
- eivarv 10y agoDropout can certainly be applied generally - it's useful as a regularization technique (especially in wide and deep networks) to combat overfitting in other fields than computer vision. CNNs can be used in other fields as well.
