Neural Networks and Deep Learning

  • Learn about the mathematics of neural networks, including backpropagation, activation functions, and gradient-based optimization.
  • Dive into advanced topics like convolutional neural networks (CNNs) and recurrent neural networks (RNNs), which involve linear algebra, calculus, and probability.

Unsupervised Learning

  • Explore clustering algorithms like k-means and hierarchical clustering, understanding the role of distance metrics and optimization.
  • Study dimensionality reduction techniques like PCA and t-SNE, applying linear algebra and statistical concepts.

Step 4: Utilize Resources and Practice
