How do I use a taxonomy and the support vector machine for question classification?

I am going to develop an open-domain natural language question-answering (NLQA) system, and will use the support vector machine (SVM) as the machine learning (ML) model for question classification. The data that I have is from a cube, containing…

In the field of Deep Learning research, what considerations do researchers take into account when inventing new neural network models?

I am not a researcher, but I am curious to know what considerations are relevant to take into account during research for the invention of a new neural network model, and what relevant knowledge researchers typically possess in the area. And an…

Is an embedding a representation of a word or its meaning?

What does the term "embedding" actually mean? An embedding is a vector, but is that vector a representation of a word or its meaning? Literature loosely uses the word for both purposes. Which one is actually correct? Or is there anything like: A…

What are the best hyper-parameters to tune in reinforcement learning?

Obviously, this is somewhat subjective, but what hyper-parameters typically have the most significant impact on an RL agent's ability to learn? For example, the replay buffer size, learning rate, entropy coefficient, etc. For example, in "normal"…

What does Brooks mean by "representation"?

For a class, I'm reading Brooks' "Intelligence without representation". The introduction is dedicated to slating representation as a focus for AI development. I've read that representation is the problem of representing information symbolically, in…

What are the typical sizes of practical/commercial artificial neural networks?

I'm interested in artificial neural networks (ANN) and I wonder how big ANNs in practical use are, for example, Tesla Autopilot, Google Translate, and others. The only thing I found about Tesla is this one: "A full build of Autopilot neural…

Why can't cognitive architectures achieve general intelligence?

Newbie here. I recently read about cognitive architectures (see: https://en.wikipedia.org/wiki/Cognitive_architecture). They are supposed to be modeled after the human mind and represent a promising approach towards artificial general intelligence…

Are neurons instantly feed forward when input arrives?

Let's say I have a neural network with 5 layers, including the input and output layer. Each layer has 5 nodes. Assume the layers are fully connected, but the 3rd node in the 2nd layer is connected to the 5th node in the 4th layer. All these numbers…

What are the major differences between multi-armed bandits and the other well-known algorithms (DQN, A3C, PPO, etc)?

I have studied in the past different algorithms, i.e. DQN, DDQN, REINFORCE, A3C, PPO, TRPO, so on. I am doing an internship this summer where I have to use a multi-armed bandit (MAB). I am a bit confused between MAB and the other above…

What does "statistical efficiency" mean in this context?

Consider the following statement(s) from Deep Learning book (p. 333, chapter 9: Convolutional Networks) by Ian Goodfellow et al. Convolution is thus dramatically more efficient than dense matrix multiplication in terms of the memory requirements…

Does the policy iteration convergence hold for finite-horizon MDP?

Most RL books (Sutton & Barto, Bertsekas, etc.) talk about policy iteration for infinite-horizon MDPs. Does the policy iteration convergence hold for finite-horizon MDP? If yes, how can we derive the algorithm?

Does gradient descent in deep learning assume a smooth fitness landscape?

I've come across the concept of fitness landscape before and, in my understanding, a smooth fitness landscape is one where the algorithm can converge on the global optimum through incremental movements or iterations across the landscape. My question…

In MCTS, what to do if I do not want to simulate till the end of the game?

I'm trying to implement MCTS with UCT for a board game and I'm kinda stuck. The state space is quite large (3e15), and I'd like to compute a good move in less than 2 seconds. I already have MCTS implemented in Java from here, and I noticed that it…
