    Study Notes

    Machine Learning

    Definition: Machine Learning is a subfield of Artificial Intelligence that involves training algorithms to learn from data and make predictions or decisions without being explicitly programmed.

    Types of Machine Learning:

    • Supervised Learning: The algorithm is trained on labeled data to learn the relationship between input and output.
    • Unsupervised Learning: The algorithm is trained on unlabeled data to discover patterns or relationships.
    • Reinforcement Learning: The algorithm learns by interacting with an environment and receiving feedback in the form of rewards or penalties.

    Machine Learning Algorithms:

    • Linear Regression: A linear model that predicts a continuous output variable.
    • Decision Trees: A tree-based model that splits data into subsets based on features.
    • Neural Networks: A model inspired by the structure and function of the human brain.
    • Support Vector Machines (SVMs): A model that finds the hyperplane that maximally separates classes.

    Applications of Machine Learning:

    • Image and Speech Recognition: Machine learning algorithms can be trained to recognize images and speech patterns.
    • Natural Language Processing: Machine learning algorithms can be used for text classification, sentiment analysis, and language translation.
    • Recommendation Systems: Machine learning algorithms can be used to recommend products or services based on user behavior.

    Natural Language Processing

    Definition: Natural Language Processing (NLP) is a subfield of Artificial Intelligence that focuses on the interaction between computers and human language.

    Components of NLP:

    • Tokenization: Breaking down text into individual words or tokens.
    • Part-of-Speech Tagging: Identifying the grammatical category of each word (e.g., noun, verb, adjective).
    • Named Entity Recognition: Identifying named entities in text (e.g., people, places, organizations).
    • Sentiment Analysis: Determining the emotional tone or sentiment of text.

    NLP Tasks:

    • Language Translation: Translating text from one language to another.
    • Text Classification: Classifying text into categories (e.g., spam vs. non-spam emails).
    • Sentiment Analysis: Determining the emotional tone or sentiment of text.
    • Question Answering: Answering questions based on the content of text.

    NLP Applications:

    • Chatbots and Virtual Assistants: NLP is used to understand and respond to user input.
    • Language Translation Software: NLP is used to translate text and speech in real-time.
    • Speech Recognition Systems: NLP is used to recognize and transcribe spoken language.
    • Text Summarization: NLP is used to summarize long documents and articles.

    Machine Learning

    • Machine learning is a subfield of Artificial Intelligence that involves training algorithms to learn from data and make predictions or decisions without being explicitly programmed.
    • Machine learning has three types: Supervised Learning, Unsupervised Learning, and Reinforcement Learning.
