Objectives

  • Master the Keras Functional API to build complex, non-linear model topologies, including multi-input and multi-output architectures for multi-task learning.
  • Develop Custom Layers and Loss Functions by overriding the build() and call() methods to implement cutting-edge research papers and unique neural behaviors.
  • Optimize Data Pipelines using the tf. data API with prefetching, caching, and parallel mapping to eliminate CPU bottlenecks and maximize GPU utilization.
  • Implement Advanced Training Loops using GradientTape and create custom Callbacks to gain granular control over the weight update and monitoring process.


Pre Requisites

  1. Intermediate Python Proficiency: You should be comfortable with Object-Oriented Programming (OOP) concepts like classes, inheritance, and decorators.
  2. Foundational Machine Learning Knowledge: A basic understanding of neural network concepts (backpropagation, layers, and activation functions) is required.
  3. Basic Keras/TensorFlow Experience: Familiarity with the Sequential API and standard model training (model. fit) will help you dive into the advanced content.
  4. No Hardware Barriers: While a GPU is recommended for training, these practice questions focus on architectural logic and can be studied on any device.


FAQ

  • Q. How long do I have access to the course materials?
    • A. You can view and review the lecture materials indefinitely, like an on-demand channel.
  • Q. Can I take my courses with me wherever I go?
    • A. Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don't have an internet connection, some instructors also let their students download course lectures. That's up to the instructor though, so make sure you get on their good side!
