Study Notes
Introduction
Artificial Intelligence (AI) has become a significant presence in our lives, transforming industries, enhancing communication, and expanding human capabilities. However, understanding AI requires a clear distinction between the concepts and technologies involved, such as unsupervised learning, AI versus Data Science (DS), defining AI, and distinguishing between AI, Machine Learning (ML), and Deep Learning (DL). Unraveling these distinctions helps clarify the role and scope of AI in various applications.
Unsupervised Learning
Unsupervised learning is one of three primary branches of machine learning, alongside supervised and reinforcement learning. In unsupervised learning, an AI model processes raw data without explicit guidance from humans. The goal is to identify patterns and relationships within the data, enabling the system to make predictions or classifications without direct human control. Examples include clustering, anomaly detection, and dimensionality reduction techniques like Principal Component Analysis (PCA) and Independent Component Analysis (ICA).
AI vs DS
While AI encompasses a broader concept of machines mimicking human intelligence, DS focuses on designing models that analyze and interpret data to discover hidden trends, correlations, and anomalies in large datasets. DS includes machine learning, statistical methods, and databases, while AI may involve elements of symbolic reasoning, expert systems, perception, agent-based decision making, and natural language comprehension. Both AI and DS contribute to modern tech innovations, providing complementary approaches to solving diverse problems.
Definition of AI
AI refers to the development of computer systems capable of performing tasks typically requiring human intelligence. These tasks include learning, reasoning, problem-solving, perception, and language understanding. AI can be categorized as either weak (narrow) AI, which simulates specific aspects of human intelligence, or strong (general) AI, which aims to emulate all forms of human intelligence.
Neural networks, genetic algorithms, fuzzy logic, and expert systems are examples of AI techniques. Neural networks imitate the behavior of neurons in the human brain, allowing computers to recognize speech, faces, and other stimuli. Genetic algorithms mimic evolutionary processes to find optimal solutions to complex problems. Fuzzy logic incorporates uncertainty and ambiguity into computations, improving the performance of decision-making systems. Expert systems capture specialized knowledge from experts in a domain and enable the system to solve similar problems in new situations.
AI vs ML vs DL
Machine learning (ML) is a subset of AI and consists of algorithms that allow computers to learn from data and make decisions without explicitly programmed instructions. ML algorithms can be divided into supervised, unsupervised, and reinforcement learning techniques. Supervised learning involves training a model using labeled data, where the correct answers are known. Unsupervised learning, as discussed earlier, uses probabilistic models to infer patterns in the data without labels. Reinforcement learning trains an agent in an environment to maximize rewards.
Deep learning (DL) is a type of neural network architecture that focuses on building hierarchical representations of data. Inspired by the structure and function of the mammalian cerebrum, deep learning models consist of multiple layers, which progressively extract higher-level abstractions from raw data. Popular deep learning architectures include Convolutional Neural Networks (CNNs) for image recognition and Recurrent Neural Networks (RNNs) for sequence prediction tasks like speech recognition and natural language processing.
