Convergence of Semi gradient TD(0) with non-linear function approximation

I am looking for a result that shows convergence of semi-gradient TD(0) algorithm with non-linear function approximation for on-policy prediction. Specifically, the update equation is given by (...

What is the relation between online learning and on-policy algorithms?

In the context of RL, there is the notion of on-policy and off-policy algorithms. I roughly understand the difference between on-policy and off-policy algorithms. Moreover, in RL, there's also the ...
