Machines that Learn Through Action: The Future of AI • Julie Pitt • YOW! 2017
Explore active inference as a framework for autonomous AI that learns through action, moving beyond traditional reinforcement learning to handle real-world complexity and uncertainty.
-
Active inference is proposed as a new framework for developing autonomous AI agents that can operate effectively in real-world environments, moving beyond traditional reinforcement learning approaches
-
Key challenges for robot/AI agents include:
- Ability to generalize across different situations
- Risk sensitivity and damage avoidance
- Balancing exploration vs exploitation
- Handling uncertainty and recovering from unexpected situations
- Operating with imperfect sensors and noisy data
-
Traditional reinforcement learning has limitations:
- Requires many training examples
- Relies on manually designed reward functions
- Poor generalization to new environments
- Lacks purposeful exploration
- Slow convergence in real-world scenarios
-
The free energy principle suggests agents should:
- Minimize prediction error
- Maintain a small set of preferred states
- Balance accuracy vs complexity in their models
- Naturally explore to reduce uncertainty
- Have intrinsic rather than external rewards
-
Benefits of active inference framework:
- Emergent intelligent behaviors
- Natural balance of exploration and exploitation
- Built-in risk sensitivity
- Parallel processing of multiple goals
- Better handling of uncertainty
- More biologically plausible learning approach
-
Moving from “Software 2.0” to “Software 3.0” requires:
- New paradigms beyond deep learning
- Focus on experience rather than just datasets
- Better handling of real-world complexity
- More efficient learning approaches
- Integration of domain expertise
