a) A language is a finite set of strings over some finite set of alphabets. A language L can be considered as a subset of the free monoid on an alphabet. It is a set of strings or sentences over some finite alphabet. Consider the following languages: L₁ = {p, q, r, s} (5,6,7,8} Evaluate the following language operations: (i) L₁ L₂ (ii) L₁ L₂ (iii) L22 (iv) L₁ and L₂ =

e3q4 Pumping Lemma for Regular Languages Here are three incorrect statements of the Pumping Lemma for regular languages. In each case, explain why the statement is not correct. Try to identify the most serious problem. (a) Suppose L is a regular language over the alphabet Σ. Then the following property must be true. For every string w € L, there exists a constant n such that |w| ≥n, and it is possible to write w as w = xyz such that i. y ‡ λ ii. |xy| ≤ n and iii. for every integer k ≥ 0, the string xyz is also in L.

Artificial intelligence Develop a Word2Vec Language Model Use a corpus , to build a Word2Vec Language Model, using Python. Each student should learn what is Word2Vec by him/herself. The language model will be a set of words and a vector of numbers (called Word Embeddings) for each word. The language model can be easily used in Python. After building the language model, each student should demonstrate it by: (1) finding similar words to a given word, and (2) Finding the cosine similarity between two words.
