That what we like can't be boiled down to an optimization function over a sparse matrix.
- tw1010 8y agoWith the right optimization function and the feature extractors, of course it could. I don't buy that at all.
- tomnipotent 8y agoBecause you're focusing on a technology solution. This isn't a technology problem. We cannot model the impossibly complicated measure of taste, the best we can do is optimize on captured data and generalize. This technique - using optimization functions over sparse matrices - has taken us as far as it can go.
