This comprehensive guide provides a structured overview of differentiable programming, along with resources to help you master it through a series of video tutorials.

This tutorial series aims to take you from the fundamentals of automatic differentiation (AD) to advanced techniques in building and training differentiable programs. We'll explore various aspects, including the theoretical underpinnings, practical implementation, and real-world applications. Whether you're a seasoned programmer or a complete beginner, this guide will provide a solid foundation for your journey into the world of differentiable programming.

Part 1: Understanding the Foundations of Automatic Differentiation

Before diving into the practical aspects of differentiable programming, it's crucial to understand the core concept of automatic differentiation. Our video tutorials in this section will cover:
What is Automatic Differentiation (AD)? We'll explore the two main approaches to AD: forward-mode and reverse-mode differentiation, explaining their strengths and weaknesses, and when each is most appropriate.
Computational Graphs: We'll delve into the visual representation of computations as directed acyclic graphs (DAGs), showing how AD leverages these graphs to efficiently compute derivatives.
Implementation Details: We'll look at how AD is implemented in popular programming languages like Python, focusing on libraries such as JAX, PyTorch, and TensorFlow. The videos will include practical examples showing how to compute gradients using these libraries.
Higher-Order Derivatives: We'll extend our understanding to computing second-order and higher-order derivatives, essential for advanced optimization algorithms and Bayesian inference.

This section will provide a strong theoretical foundation for understanding how AD works under the hood, enabling you to confidently use and implement it in your own projects.

Part 2: Building Differentiable Programs

This part of the tutorial shifts from theory to practice, demonstrating how to construct and manipulate differentiable programs. Key areas covered will include:
Vectorization and Broadcasting: We'll explore efficient ways to perform computations on arrays and tensors, maximizing the performance of AD algorithms.
Custom Differentiable Functions: You'll learn how to define your own differentiable functions, expanding the capabilities of existing automatic differentiation libraries. This includes techniques for handling discontinuities and other complexities.
Gradient-Based Optimization: We'll discuss various optimization algorithms such as gradient descent, Adam, and RMSprop, showing how they utilize gradients computed through AD to find optimal solutions.
Control Flow and Differentiation: Dealing with conditional statements and loops in differentiable programs can be tricky. Our tutorials will cover techniques for handling these complexities and ensuring the correctness of gradient computations.

This section will provide hands-on experience in constructing and manipulating differentiable programs, empowering you to solve increasingly complex problems.

Part 3: Advanced Topics and Applications

The final part will explore advanced concepts and real-world applications of differentiable programming:
Deep Learning and Neural Networks: We'll show how AD is fundamental to training deep learning models, illustrating the backpropagation algorithm and its connection to reverse-mode AD.
Differentiable Physics: This exciting field uses differentiable programming to solve physics-based simulations. We'll explore examples involving fluid dynamics, robotics, and other areas.
Bayesian Inference and Probabilistic Programming: We'll show how AD facilitates efficient inference in probabilistic models, enabling the estimation of parameters and uncertainty quantification.
Optimization in Robotics and Control: We will cover the application of differentiable programming to tasks such as trajectory optimization and reinforcement learning.
Large-Scale Optimization Techniques: We will discuss strategies for efficiently optimizing models with a vast number of parameters.

This section showcases the power and versatility of differentiable programming, demonstrating its applicability to a wide range of scientific and engineering domains.
