Introduction to AI Basics
Welcome to our beginner’s guide on Artificial Intelligence (AI)! AI is a branch of computer science that aims to create intelligent machines capable of performing tasks that would normally require human intelligence. In other words, it’s about creating systems that can learn from data, make decisions, and solve problems like humans.
Understanding AI
AI can be categorized into three types:
1. **Artificial Narrow Intelligence (ANI):** These are systems designed to perform a narrow task exceptionally well, such as facial recognition, driving a car, or playing chess. Google’s AlphaGo is a prime example of ANI, beating a world champion in the complex game of Go.
2. **Artificial General Intelligence (AGI):** AGI systems can perform any intellectual task that a human being can do. They can understand, learn, and adapt to new situations. AGI is still a theoretical concept and no system has yet achieved this level of intelligence.
3. **Artificial Superintelligence (ASI):** ASI is a hypothetical agent that possesses intelligence far surpassing that of the brightest and most gifted humans in practically every field, including scientific creativity, general wisdom, and social skills. This is also a theoretical concept, and no ASI has been created yet.
Introduction to Machine Learning
Machine Learning (ML) is a subset of AI that focuses on the development of algorithms and statistical models that enable computers to learn from data and make predictions or decisions without being explicitly programmed.
There are several types of ML algorithms, each with its unique strengths and weaknesses:
1. **Supervised Learning:** In this type of learning, the algorithm is trained on a labeled dataset, i.e., data that is already categorized or classified. The goal is to learn a mapping function from input to output based on this data. Examples of supervised learning algorithms include Linear Regression, Logistic Regression, Decision Trees, and Support Vector Machines.
2. **Unsupervised Learning:** Unsupervised learning algorithms are used when the data is not labeled. The algorithm’s goal is to find hidden patterns or structure in the data. Clustering and Dimensionality Reduction are common unsupervised learning techniques.
3. **Reinforcement Learning:** Reinforcement learning is about training an agent to make a sequence of decisions in an environment to maximize a reward. The agent learns from its experiences and the consequences of its actions. DeepMind’s AlphaGo Zero is an example of reinforcement learning.
4. **Semi-Supervised Learning:** As the name suggests, this type of learning is a combination of supervised and unsupervised learning. It’s used when only a small portion of the data is labeled.
