Dive into the exciting world of reinforcement learning with the Practical RL course! This innovative course, offered on-campus at HSE and YSDA, is designed to be friendly for both English and Russian-speaking online students. Let’s embark on an adventurous journey through the concepts, practical applications, and troubleshooting tips to help you excel in this field.

Getting Started with Practical RL

The core philosophy of this course can be summarized within three key tenets:

• Optimize for the curious: Curiosity drives learning! Explore extra materials and resources to expand your knowledge beyond what’s covered.
• Practicality first: Hands-on labs complement theoretical learning, helping you “feel” reinforcement learning concepts through real-world applications.
• Git-course: Take an active role! Suggest improvements through pull requests if you discover areas for enhancement.

Course Structure and Syllabus

The course is structured across ten weeks, covering various aspects of reinforcement learning:

• Week 1: Introduction
• Week 2: Value-based methods
• Week 3: Model-free reinforcement learning
• Week 4: Deep Learning Recap
• Week 4: Approximate (Deep) RL
• Week 5: Exploration
• Week 6: Policy Gradient methods
• Week 7: Reinforcement Learning for Sequence Models
• Week 8: Partially Observed MDP
• Week 9: Advanced policy-based methods
• Week 10: Model-based RL

Understanding the Code: An Analogy

Let’s break down a sample code that integrates the principles of reinforcement learning, making it easier to grasp its functionality. Think of code that implements a reinforcement learning algorithm as a recipe:

• Ingredients: Similar to gathering groceries, the code requires specific libraries (like TensorFlow or PyTorch) and data to work effectively.
• Prepping: Just as you would chop and prepare ingredients, the code needs to set up the environment and parameters, defining how the agent interacts with it.
• Cooking Steps: Following a step-by-step approach, the code updates the agent’s policy based on the rewards it receives, akin to adjusting a recipe based on taste-testing as you cook.
• Serving: Finally, once the dish is ready, we can test how well it performs in the environment, similar to tasting the final dish to see if it meets expectations.

Troubleshooting Tips

While setting out on your reinforcement learning journey, you may encounter various challenges. Here are some troubleshooting ideas to help you:

• Check your dependencies: Make sure all required libraries are installed.
• Review the course materials for relevant FAQs or technical issues.
• If you encounter errors, carefully read the error messages they often provide insight on where the issue lies.
• Consult the Online Student Survival Guide for useful tips.
• If you need assistance, feel free to fill out the anonymous feedback form.
