Fundamentals of Neural Networks - Tensor and Matrix

The video tutorial introduces matrices and tensors, explaining their definitions and differences. It covers the basic properties of matrices, including their dimensions and operations in linear algebra. The tutorial then transitions to the concept of tensors, detailing their dimensions and how they relate to matrices. The explanation includes examples of 1D, 2D, and 3D tensors, highlighting their structure and representation in computer science, particularly in TensorFlow. The video aims to build foundational knowledge for understanding convolutional operations in future lectures.
