How AI Agents Learn to Pick the Best Future Actions
A method for an AI agent to predict which actions will yield the highest rewards by analyzing past experiences and refining its decision-making model.
Original patent title: “Action selection with a reward estimator applied to machine learning”
A method for an AI agent to predict which actions will yield the highest rewards by analyzing past experiences and refining its decision-making model. Granted to Sony Corp in 2019 with 14 claims, and it is expected to expire in 2035.
Coverage
What does this patent actually cover?
This patent describes a system where an AI agent learns from its history to make better decisions. It records 'action history data'—which includes the state the agent was in, the action it took, and the reward it received. The system uses this data to build a 'reward estimator' that predicts how much reward a future action might generate. By comparing these predicted rewards for various possible next steps, the agent selects and executes the action with the highest estimated value. This process allows the agent to continuously improve its performance as it gathers more data.
The gap
What does this patent NOT cover?
- Does not cover general machine learning algorithms that do not specifically use reward estimation based on action history data.
- Does not cover hardware-specific implementations, as the claimsclaimsThe numbered statements at the end of a patent that legally define what the inventor owns.Read more → focus on the logical process performed by a CPU.
- Does not cover reinforcement learning methods that rely solely on trial-and-error without a basis-function-based reward estimator.
These exclusions are unique to PatentBrief — derived from the actual claim language, not patent-office boilerplate.
Key facts
What made this novel
The system uses 'basis functions' to transform raw state and action data into 'feature amount vectors,' which allows the AI to map complex, high-dimensional experiences into a space where it can more easily calculate and predict rewards.

Why it matters
The bigger picture
This technology is fundamental to modern autonomous systems, such as robotics and game AI, where an agent must navigate complex environments. By formalizing how an agent evaluates the potential 'reward' of its next move, Sony provides a framework for more efficient decision-making in unpredictable scenarios. It represents a shift toward more structured, data-driven behavior in automated agents.
