Study Notes

Artificial Intelligence (AI)

AI is a broad field encompassing the development of intelligent agents, which are systems that can reason, learn, and act autonomously.
It aims to create machines capable of performing tasks that typically require human intelligence.
AI encompasses various methods and approaches, including machine learning, natural language processing, and computer vision.
Key goals of AI include problem-solving, knowledge representation, planning, learning, and communication.
AI systems can be rule-based, where specific rules dictate their behaviour, or data-driven, where algorithms learn patterns from data.

Natural Language Processing (NLP)

NLP is a subfield of AI focused on enabling computers to understand, interpret, and generate human language.
Key tasks in NLP include text classification, machine translation, summarization, question answering, and sentiment analysis.
NLP uses techniques like tokenization, stemming, and part-of-speech tagging to process text data.
Deep learning models, particularly recurrent neural networks (RNNs) and transformers, have significantly advanced NLP capabilities.
NLP applications include chatbots, virtual assistants, and language-based information retrieval systems.

Machine Learning (ML)

ML is a subset of AI that focuses on enabling systems to learn from data without being explicitly programmed.
ML algorithms identify patterns and make predictions or decisions based on input data.
Different types of ML algorithms include supervised learning, unsupervised learning, and reinforcement learning.
Supervised learning uses labeled data to train models, while unsupervised learning identifies patterns in unlabeled data.
Deep learning, a subset of ML, employs artificial neural networks with multiple layers to learn complex patterns from large datasets.

Computer Vision

Computer vision is a field that focuses on enabling computers to "see" and interpret images and videos.
It involves techniques for object recognition, image classification, and scene understanding.
Computer vision applications include facial recognition, object detection in images, and medical image analysis.
Convolutional neural networks (CNNs) are commonly used algorithms in computer vision due to their ability to automatically learn feature representations from image data.
Techniques are also used for image segmentation, which isolates specific objects in images.

Neural Networks

Neural networks are computing systems inspired by the biological neural networks in the human brain.
They consist of interconnected nodes, or neurons, organized in layers.
The nodes process information and pass it to the subsequent layer.
Deep learning heavily relies on neural networks, particularly deep neural networks with many layers.
Architectures like feedforward neural networks, recurrent neural networks (RNNs), and convolutional neural networks (CNNs) differ in their structure and applications.

Reinforcement Learning (RL)

RL is a type of machine learning where an agent learns to interact with an environment to maximize a reward.
The agent takes actions in the environment and receives feedback (rewards or penalties) based on its actions.
RL algorithms adjust the agent's behaviour to improve its performance over time.
RL applications include game playing, robotics control, and resource management.
Deep reinforcement learning, combining RL with deep neural networks for more complex tasks, has led to significant progress in various fields.
