I seem to be doing a lot more mobile (i.e. Android) computing these days. With the baby I rarely have time to sit down at the computer.
@cwebber Yeah, that's probably the main point, he keeps learning and adapting, so every day is different.
Another problem is the impossibility of controlling all the input variables, or reading the internal state (hungry, tummy ache, tired, etc). In the beginning the output was more or less binary: crying, not crying. But now we're picking up more nuanced output which helps :-)
