some of the other stolen ideas include
- stock market prediction: People are already using machine learning techniques to predict the movement of the stock market. It is said that some of the banks make a lot of money by predicting the fluctuations in the currencies of different countries. I guess there is a lot of money that can be made by creating the write model by predicting the movemets of a financial institution.
- an other idea that one of my friends is working on is to identify related tunes from different songs, or given a tune find the most appropriate song from a database.
