Personal data collection for learning
We have the means to query data in interesting ways
We can query data in interesting ways, feed them into neural networks and create regressions with logistical regressions. We just need the data to do it
We could predict when you would go to a cafe based on instances of you going to a cafe. If you plot "went to cafe" on the Y axis and X axis as a timestamp.
You can run a neural network and predict when going to a cafe will happen. You could train this system and it would get more accurate over time.
Yeah, you could do all of that, and much more, like the things mentioned under Social Real-Time Data Sharing. ;)
