Recently I have been thinking about some of following problems:
- Collecting data from various sources and analyzing it and use it for making better decisions.
- Patients diagnosis at hospitals.
- Travel/transportation data.
- Students performance in school and other places. This data can be combined with his/her preferences/hobbies and used to offer career advise.
- Hardware re-cycling.
- Portable device to measure quality of air, water and food, quickly.
