What is Artificial Intelligence?

Artificial intelligence refers to computer systems or machines that are designed to perform tasks that would otherwise require human intelligence. AI systems can learn from data and experience, adapt to new inputs, and perform tasks like speech recognition, visual perception, decision-making, and language translation.

Machine Learning

Machine learning is a subset of AI that enables algorithms and systems to learn from data without being explicitly programmed. Machine learning algorithms identify patterns in data in order to make predictions or decisions without human intervention. Popular machine learning approaches include:

  • Supervised learning – Algorithms are trained on labeled datasets that contain both the inputs and desired outputs. Common supervised learning tasks include classification and regression.
  • Unsupervised learning – Algorithms are given unlabeled data and tasked with finding hidden patterns and structure within it. Clustering and dimensionality reduction are common unsupervised learning tasks.
  • Reinforcement learning – Algorithms learn by interacting with an environment and receiving feedback in the form of rewards or penalties. The goal is to maximize rewards through trial-and-error.
  • Deep learning – Advanced machine learning techniques that use neural networks with multiple layers. Enables learning from large, complex datasets.

Neural Networks

Neural networks are computing systems modeled after the biological neural networks in human brains. They consist of layers of simple computing nodes or “neurons” that transmit signals between layers. By adjusting the connections between nodes, neural nets can identify patterns and features in vast amounts of data. Key types of neural networks include:

  • Convolutional neural networks (CNN) – Used for computer vision and image recognition.
  • Recurrent neural networks (RNN) – Used for natural language processing and speech recognition. Can retain memory of prior inputs.
  • Generative adversarial networks (GAN) – Two networks contest with each other to generate new, synthetic instances of data. Used for image and video generation.

Algorithms are sets of defined steps or rules to accomplish a task. Machine learning algorithms enable computers to identify patterns in data and make predictions or decisions based on those patterns. Different algorithms are better suited for specific types of problems.


Datasets are collections of data points used to train and test machine learning models. Quality datasets enable models to learn robust patterns and relationships. Image datasets for computer vision and large text corpuses for NLP are common.

Model Training

Training is the process of feeding data through a machine learning algorithm to tune the model parameters and optimize its predictive accuracy. Models are trained until a desired level of performance is reached.


Classification assigns input data points into distinct categories or classes. Image and speech recognition rely on classification algorithms. Logistic regression and support vector machines are popular techniques.


Clustering is an unsupervised technique to group data points based on similarities. It discovers intrinsic patterns without pre-defined categories. Used for customer segmentation, social network analysis and more.
