Hidden linear function problem
WebConsider a supervised learning problem where we have access to labeled training examples (x^{(i)}, y^{(i)}).Neural networks give a way of defining a complex, non-linear form of hypotheses h_{W,b}(x), with parameters W,b that we can fit to our data.. To describe neural networks, we will begin by describing the simplest possible neural network, one … Web8 de fev. de 2024 · The question asks about "arbitrary functions" and "any problem"; the accepted answer talks only about continuous functions. The answer to the question as stated now, in both versions, is clearly "no". Some fun counterexamples: "Any problem" includes Turing's Entscheidungsproblem, which is famously unsolvable.

WebIn the Bernstein–Vazirani problem, the hidden function is implicitly specified in an oracle; while in the 2D hidden linear function problem (2D HLF), the hidden function is … Web4 de mai. de 2024 · Now, it is still a linear equation. Now when you add another layer, a hidden one, you can operate again on the 1st output, which if you squeeze between 0 and 1 or use something like relu activation, will produce some non linearity, otherwise it will just be (w2(w1*x + b1)+b2, which again is a linear equation not able to separate the classes 0 ...
WebThe problem is to find such a vector z (which may be non-unique).
