Instructor: Dr. Ashutosh Modi

Assignment-3

There are 3 main tasks in Assignment-3:

1. Neural Network Implementation from Scratch for Word2Vec using Wikipedia Text
2. Naive Bayes Classifier for Topic classification on Wikipedia Articles
3. Expectation-Maximization Based clustering on Wikipedia Articles

The data can be fetched using the datasets API as follows:

from datasets import load_dataset

# Word2Vec Dataset
word2vec_train = load_dataset("Exploration-Lab/CS779-Fall25", "Assignment-3-word2vec", split="train")
word2vec_test = load_dataset("Exploration-Lab/CS779-Fall25", "Assignment-3-word2vec-analogy", split="test")

# Naive Bayes
naive_bayes_train = load_dataset("Exploration-Lab/CS779-Fall25", "Assignment-3-naive-bayes", split="train")
naive_bayes_test = load_dataset("Exploration-Lab/CS779-Fall25", "Assignment-3-naive-bayes", split="test")

# Expectation-Maximization
em_train = load_dataset("Exploration-Lab/CS779-Fall25", "Assignment-3-em", split="train")
em_test = load_dataset("Exploration-Lab/CS779-Fall25", "Assignment-3-em", split="test")
