Statistical efficiency in this context essentially means that a CNN would require fewer training examples than a fully connected network to learn. Intuitively this seems reasonable: more parameters to learn should mean more samples needed. Of course it is always desirable to minimise the number of training samples needed, so that's a definite advantage of ...

In essence, your question is about convergence of infinite series. The mathematical discipline that studies such series is hundreds (if not thousands) years old an has nothing to do with "hardware architecture". A basic example of an infinite series is the geometric series: $$S = 1 + \gamma + \gamma^2 + \gamma^3 + \dots$$ Note that the series is ...

A quick review of resolving expectations: If you know that a discrete random variable $X$, drawn from set $\mathcal{X}$ has probability distribution $p(x) = \mathbf{Pr}\{X=x \}$, then $$\mathbb{E}[X] = \sum_{x \in \mathcal{X}} xp(x)$$ This equation is the core of what is going on when resolving the expectation in your quoted equation. Resolving the ...

It's much easier to deal with logarithms, as the relevant numbers are usually very small or very large. If you have a long exponential expression, it's hard to see the difference, but if you're looking at 4.3 vs 5.6, you can immediately see what's happening. And logarithms are a well-known (and well-understood) way of achieving this compression. You can ...

In its most raw form, convolution is defined as: $(f*g)(t) = \int_{-\infty}^\infty f(\tau) \cdot g(t-\tau) d\tau$. Here, t doesn't represent the time domain. Infact, it represents the real valued argument the book is talking about. In this notion, at moment t, convolution can be thought of as a weighted average of the function $f(\tau)$ weighted by $g(–\tau)$...

I think that these terms may be used inconsistently across sources. If someone says held-out dataset, I would immediately think of a dataset that is not used for training, but can be used for anything else, validation (hyper-parameter tuning or early stopping) or testing; so, to determine what they are referring to, I would probably take into account the ...

It is very confusingly worded, and I would think it's incorrect according to linguistic terminology. A lemma is the canonical form of a word, commonly the infinitive of a verb, the nominative singular of a noun, and the positive of an adjective. The inflected forms belonging to a word would the the forms used for other tenses and persons etc for verbs, case ...

Please note: I am only referring the decision boundary to be a line for simplicity, more often than not it is a hyperplane which is difficult to visualize and spans over n dimensions where n is the dimensionality of your feature space. The explanation is toned in a more general way for emphasizing explainability. Answer What are the 'noisy factors' here? ...

I would like to add details to Oliver's answer. From the book "Pattern Recognition and Machine Learning" by Bishop (Section 1.2.5): In practice, it is more convenient to maximize the log of the likelihood function. Because the logarithm is monotonically increasing function of its argument, maximization of the log of a function is equivalent to ...

A bag-of-words-model (BOW) is usually used to represent a text: you throw all the words together (as if in a bag), without keeping track of their sequence. This is a gross simplification over a text, as word sequencing plays an important role in creating the meaning of a text. But on the positive side it's easier to handle, eg in information retrieval tasks, ...

I can't really make much sense of Eisenstein's distinction between distributional and distributed. And I think in your question you actually mix up the two terms as well, as distributed semantics involve symbolic structures, whereas distributional semantics are numerical vectors according to his definition. EDIT: actually, he seems to mix it up himself there?...

Having a sound understanding on language processing will help you understand all its concepts. This summarise must reads for NLP.

I propose you try this. It's about modern Natural Language Processing, Computational Linguistics and Speech Recognition, including Embeddings methods.

Some of the books that you mention are often used as reference books in introductory courses to machine learning or artificial intelligence. For example, if I remember correctly, in my introductory course to machine learning, the professor suggested the book Pattern Recognition And Machine Learning (2006) by Bishop, although we never used it during the ...

Pattern Recognition And Machine Learning is a great theoretical book. I don't know anything better on standard ML. I read several pages from it myself and all my colleagues researchers suggest to look there if you are not sure about some concepts. The 2 problems with it are that it's huge and it doesn't cover almost all deep learning models known for today. ...

Foundations of Deep Reinforcement Learning: Theory and Practice in Python (Addison-Wesley Data & Analytics Series) 1st Edition This book does not give a detailed background information on Markov Decision Processes, different Bellman equations and relationships between the value function and action-value function, etc. It focuses on Deep Reinforcement ...

Artificial intelligence is a broad field: that's why Artificial Intelligence: A Modern Approach may look a bit dense to newcomers, given that it covers many different aspects of AI, such as search, machine learning, and natural language processing. The first book in this answer is a good book, but it focuses on evolutionary computation approaches, which are ...
