Vectors & Dot Products (Linear Algebra Part 1)
Explore how real-world data is encoded into feature vectors, transformed through basic vector arithmetic, and evaluated by a neural network.
Lessons in this Topic
The Feature Vector
Learn how real-world data is structured into ordered numeric lists and vector coordinates to create mathematical identity profiles in AI systems.
Vector Addition and Scaling
Master vector addition and scalar multiplication to transform feature states, scale attributes, and combine multidimensional data profiles.
The Dot Product and Weights
Learn how the dot product multiplies input features by weights to accumulate influence, calculate raw decision scores, and power neural network layers.
From Vectors to Neural Networks
Connect feature vectors and dot products directly to neuron weights, biases, and activation thresholds in modern deep learning architectures.
Vectors and Dot Products In Practice
Solidify your understanding with hands-on practice problems, calculating vector arithmetic, projections, and dot products manually.
