📌 On-Policy Reinforcement Learning Summary
On-policy reinforcement learning is a method where an agent learns to make decisions by following and improving the same policy that it uses to interact with its environment. The agent updates its strategy based on the actions it actually takes, rather than exploring alternative possibilities. This approach helps the agent gradually improve its behaviour through direct experience, using feedback from the outcomes of its own choices.
🙋🏻♂️ Explain On-Policy Reinforcement Learning Simply
Imagine you are learning to ride a bicycle. Each time you try, you use the same style or technique and adjust it little by little based on what works and what does not. You are not switching to other people’s methods but improving your own way as you go along.
📅 How Can it be used?
On-policy reinforcement learning can help a robot learn to navigate a warehouse by continuously refining its own route planning decisions.
🗺️ Real World Examples
In video game AI, on-policy reinforcement learning can be used to train a character to complete levels efficiently. The AI character continually updates its strategy based on the results of its own actions during gameplay, leading to better performance over time.
A self-driving car system can use on-policy reinforcement learning to improve its driving by learning from its actual driving experiences, adjusting its decisions based on the outcomes of its own actions on the road.
✅ FAQ
What makes on-policy reinforcement learning different from other methods?
On-policy reinforcement learning is unique because the agent learns from the exact actions it takes while following its own strategy. Instead of considering what could have happened with different choices, the agent sticks to its current approach and adjusts it based on real experiences. This hands-on learning helps the agent steadily improve by relying on direct feedback from its own decisions.
Why is on-policy reinforcement learning useful for training agents?
On-policy reinforcement learning is useful because it lets agents adapt and improve as they go, using the experiences they collect first-hand. This approach makes learning more stable and helps avoid confusion from trying out too many unrelated strategies. It is a practical way to teach agents to make better choices over time.
Can you give a simple example of on-policy reinforcement learning in action?
Imagine a robot learning to navigate a maze. With on-policy reinforcement learning, the robot tries different paths based on its current plan and learns from the actual routes it takes, rather than guessing about routes it has not tried. Over time, it uses what it has learned from its own journeys to get better at finding the exit.

💡Other Useful Knowledge Cards
Transferable Representations
Transferable representations are ways of encoding information so that what is learned in one context can be reused in different, but related, tasks. In machine learning, this often means creating features or patterns from data that help a model perform well on new, unseen tasks without starting from scratch. This approach saves time and resources because the knowledge gained from one problem can boost performance in others.
Smart Contract Security
Smart contract security refers to the practice of protecting digital agreements that run automatically on blockchain networks. These contracts are made of computer code and control assets or enforce rules, so any errors or weaknesses can lead to lost funds or unintended actions. Security involves careful coding, testing, and reviewing to prevent bugs, hacks, and misuse.
Neural Network Efficiency
Neural network efficiency refers to how effectively a neural network uses resources such as time, memory, and energy to perform its tasks. Efficient neural networks are designed or optimised to provide accurate results while using as little computation and storage as possible. This is important for running models on devices with limited resources, such as smartphones, or for reducing costs and environmental impact in large-scale data centres.
Partner Network Strategy
A Partner Network Strategy is a plan that organisations use to build and manage relationships with other companies, known as partners. These partners can help sell products, provide services, or support business growth in various ways. The strategy sets out how to choose the right partners, how to work together, and how to share benefits and responsibilities. By having a clear strategy, businesses can reach new customers, enter new markets, and improve what they offer through collaboration. It also helps avoid misunderstandings and ensures that everyone involved knows their role and what is expected.
Decentralized Data Sharing
Decentralised data sharing is a way for people or organisations to exchange information directly with each other, without needing a central authority or middleman. Instead of storing all data in one place, the information is spread across many different computers or systems. This approach aims to improve privacy, security and control, as each participant manages their own data and decides what to share.
