Course Introduction

Have you ever wondered how devices can recognize faces, predict the weather, navigate cars, or extract insights from huge datasets—often outperforming humans at specific tasks? The answer lies in mathematics: the foundational language that enables computers and intelligent systems to reason, learn, and optimize. In this course we’ll demystify those mathematical ideas and show how they are applied in real-world computing systems such as computer vision, recommendation engines, and optimization pipelines. Expect practical intuition, hands-on examples, and conceptual clarity so you can use mathematics confidently in applied projects. Hi — I’m Alan Chapman, and I’ll guide you through the Mathematics for Computing course. Below is an overview of what you’ll learn and how the course is structured.

What this course covers

Linear algebra: vectors, matrices, and tensors — the data structures used to represent images, audio, and model parameters.
Calculus: derivatives, gradients, and partial derivatives — the math of change used to optimize models and tune parameters.
Gradient-based optimization and backpropagation: how models learn by propagating error gradients through layered architectures.
Probability and statistics: modeling uncertainty, Bayes’ theorem, and statistical inference for decision-making and estimation.
Practical examples and intuition: applying theory to real problems in machine learning, graphics, and optimization.

Learning outcomes

Build and manipulate vector/matrix/tensor representations.
Compute gradients and partial derivatives for multivariable functions.
Explain and implement backpropagation and basic gradient descent algorithms.
Use probability distributions and Bayes’ theorem to reason under uncertainty.
Translate mathematical concepts into working code and model implementations.

Module 1 — Linear Algebra Linear algebra provides the language for structured data and transformations. You’ll learn:

Vector and matrix operations: addition, scalar multiplication, dot products, and matrix multiplication.
Matrix decompositions and their uses (conceptual overview).
Tensors and higher-dimensional arrays used in deep learning frameworks.

Module 2 — Calculus and Gradients Calculus explains how outputs change when inputs vary. Key topics include:

Single-variable derivatives and gradients.
Partial derivatives for multivariable functions.
Using gradients in optimization algorithms such as gradient descent.

The image features a person speaking in front of graphics related to calculus, specifically focusing on partial derivatives with a graph showing difficulty levels over distance.

Module 3 — Optimization and Backpropagation Gradient-based optimization is the backbone of modern machine learning. We’ll cover:

Gradient descent variants (batch, stochastic, mini-batch).
Backpropagation: computing gradients efficiently through layered models.
Practical considerations: learning rates, momentum, and convergence.

Example: Simple gradient descent pseudocode

initialize parameters θ
repeat until convergence:
  compute gradient g = ∇_θ Loss(θ)
  θ = θ - η * g    # η is the learning rate

The image illustrates the concept of backpropagation with a neural network diagram, showing weights, sums, and an activation function, alongside a woman smiling and images of TV shows for recommendation systems.

Module 4 — Probability and Statistics Reasoning under uncertainty is essential for robust systems. You’ll study:

Probability distributions and expectations.
Bayes’ theorem and Bayesian thinking for updating beliefs.
Statistical inference and hypothesis testing for data-driven decisions.

The image shows a person in front of a presentation slide about "Bayes' Theorem," featuring two bar charts labeled "Guess" and "More Accurate Guess."

Community and learning format This course emphasizes hands-on learning and discussion. You’ll work through examples, implement algorithms, and participate in a supportive community where you can ask questions and share solutions.

This course focuses on the core mathematical concepts that enable computing systems. Expect hands-on examples and intuitive explanations to help bridge theory and practice.
