How can I understand the derivation of first order model agnostic meta learning?

Regarding the first order model, ∇θi−1θi−1=I in a similar way that dfdx=1 for f(x)=x. Strictly speaking, I should be a vector of 1s with the same dimensionality as θi−1, but they are probably abusing notation here and putting such a vector as the diagonal elements of a matrix. Alternatively (actually, the most likely…

Is lisp still used today in the context of machine learning?

The answer to - Is lisp still used is - LISP was popular back in the old days of AI because of the functional syntax, which worked well with the GOFAI paradigm of the time. Nowadays most researchers have given up on the classical computational theory of mind (read: language of thought), and thus also the GOFAI…

How can the value iteration pseudocode algorithm be translated to C++?

At line 10: The value function is represented as V[s], which has bracket notation-like arrays. Is this a separate method or just a function of the value with a given state? Why is S inside the brackets? Is this supposed to be an array with as many elements as S? This is just a notation that the value function is a…

What is a semantic gap?

In terms of transfer learning, semantic gap means different meanings and purposes behind the same syntax between two or more domains. For example, suppose that we have a deep learning application to detect and label a sequence of actions/words a1,a2,…,an in a video/text as a "greeting" in a society A. However, this…

Why is td lambda returns used rarely in policy ingredients?

Regarding the td lambda and Gλt, That can be done. For example, Chapter 13 of the 2nd edition of Sutton and Barto's Reinforcement Learning book (page 332) has a pseudocode for "Actor Critic with Eligibility Traces". It's using Gλt returns for the critic (value function estimator), but also for the actor's policy…

Explain Sql data conditioning?

When someone asks me a question and I don't know the answer, I tell them I don't know the answer, and then I ask them to tell me what they think the answer is. Maybe you should do that next time. If you're in an interview, I don't think you'll be judged worse for asking, since either way the interviewer already knows…
