### My cross entropy loss gradient calculation is wrong according to the answer key

For the first problem your $O_2$ is mistaken and should be corrected as below  \begin{aligned} O_2 &= \text{Sig} \left( -0.6 - 0.1 \cdot 2 + 0.2 \cdot 6 \right) \\ &= \text{Sig} \left( 0.4 \...

### What's wrong with my answer to this constraint satisfaction problem, which needs to be solved the AC-3 algorithm?

To satisfy $D\ne A$, for each element in the domain of $D$, say $d$, there must be at least one element in the domain of $A$, say $a$, that $d \ne a$. Domain of $D$: $\{ 1, 2, 3, 4 \}$ Domain of $A$:...

### Why is it useful to track loss while model is being trained?

The loss function (aka cost function) measures the correctness of the predictions of the model. For example, a simple cost function could be $|y - f(x)|$, where $\hat{y} = f(x)$ is the prediction ...

### Prove that in such cases, it is possible to ﬁnd an ERM hypothesis for $H_n$ in the unrealizable case in time $O(mnm^{O(n)})$

Here's a rough proof sketch that might be clearer, but is probably less precise, than the solution you already have. We have a sequence of hypotheses classes, but the problem actually only asks us to ...
