Section 1.1: Learn Python

Why Python?

Python serves as the foundation for data science and AI development. Its straightforward syntax and extensive libraries make it an indispensable skill for aspiring AI professionals.

How to Master Python:

• Start with Basics: Familiarize yourself with Python syntax, data structures, and control flow. Platforms like Codecademy, Coursera, and freeCodeCamp offer excellent beginner courses.
• Practice Coding: Work on small projects and tackle problems on platforms like LeetCode or HackerRank to enhance your coding abilities.
• Learn Libraries: Focus on essential libraries such as NumPy, Pandas, and Matplotlib for data manipulation and visualization.

Estimated Time: 2-3 weeks

Section 1.2: Learn Basic NLP

Why Basic NLP?

Natural Language Processing (NLP) is essential for interpreting and generating human language, a fundamental element of Generative AI.

How to Get Started:

• Understand Key Concepts: Learn about tokenization, part-of-speech tagging, named entity recognition, and sentiment analysis.
• Explore Libraries: Get acquainted with libraries like NLTK (Natural Language Toolkit) and spaCy.
• Hands-On Practice: Execute basic NLP tasks using datasets available on platforms like Kaggle.

Basic NLP Topics:

• One-Hot Encoding: Represents words as binary vectors indicating their presence.
• Bag of Words (BoW): Counts word frequencies in a document while ignoring order and grammar.
• TF-IDF: Measures word importance based on frequency in a document and rarity across a corpus.
• Word2Vec: Converts words into dense vectors capturing their meanings through CBOW or Skip-gram models.
• Average Word2Vec: Averages word vectors in a document to create a single vector representation.

Estimated Time: 1-2 weeks

Section 1.3: Learn Advanced NLP

Why Advanced NLP?

Advanced NLP techniques are vital for engaging with complex models and handling extensive language tasks.

How to Advance:

• Deep Dive into Modern Methods: Explore transformers, attention mechanisms, and BERT (Bidirectional Encoder Representations from Transformers).
• Explore Pre-trained Models: Understand how to fine-tune models for specific tasks and grasp the concept of transfer learning.
• Hands-On Projects: Take on more sophisticated NLP tasks, such as text generation and machine translation.

Advanced NLP Topics:

• RNN (Recurrent Neural Network): Processes sequences while maintaining a hidden state across steps.
• LSTM RNN (Long Short-Term Memory): Manages long-term dependencies with memory cells and gates.
• GRU RNN (Gated Recurrent Unit): A simplified LSTM with fewer gates, faster to train.
• Bidirectional LSTM RNN: Processes sequences in both directions to capture context from both ends.
• Encoder-Decoder: Encodes input into a context vector and decodes it into an output sequence for tasks like translation and summarization.
