Microsoft researchers introduce theoretical framework incorporating Bayesian intention variable using variational Bayesian theory

Are you intrigued by the fascinating world of decision-making and behavior modeling in biological and artificial agents? If so, then you’re in for a treat with this blog post! Today, we delve into the innovative research that explores the synergies between habitual and goal-directed behaviors through a groundbreaking Bayesian behavior framework. Get ready to uncover the secrets behind how habits and goals interact in decision-making processes!

Unifying Habitual and Goal-Directed Behaviors

In the realm of decision-making, habitual behaviors and goal-directed actions have often been viewed as separate entities. Habits are automatic responses ingrained through experience, while goal-directed behaviors require deliberate planning to achieve specific outcomes. However, Microsoft researchers have introduced a new Bayesian behavior framework that bridges the gap between these two types of behaviors. By utilizing variational Bayesian methods, they aim to synergize habitual and goal-directed behaviors in biological and artificial agents.

The Bayesian Intention Variable

Central to the proposed framework is the concept of the Bayesian intention variable, a dynamic intention that adjusts based on sensory cues and specific goals. This variable allows for a seamless transition and interaction between habitual and goal-directed behaviors, offering agents the ability to leverage efficiency and flexibility in decision-making processes.

Key Observations from the Framework

Through experimentation in vision-based sensorimotor tasks, the researchers made significant observations:

  1. Transition from Goal-Directed to Habitual Behavior: Agents naturally gravitated towards faster, habitual actions after repetitive trials, reducing the computational demands on goal-directed processes.

  2. Behavior Change After Reward Devaluation: Agents displayed resilience in their habitual behaviors despite changes in reward values, mirroring real-world behavioral patterns observed in psychology.

  3. Zero-Shot Goal-Directed Planning: Agents effectively tackled new goals without additional training, showcasing the framework’s ability to generalize behaviors by leveraging pre-developed habitual skills.


In conclusion, the synergy between habitual and goal-directed behaviors in decision-making processes offers a new perspective on behavior modeling. With the Bayesian behavior framework, agents can efficiently balance efficiency and adaptability, enhancing their decision-making processes. This research not only bridges the gap between habitual and goal-directed actions but also sets the stage for future advancements in understanding and modeling behavior in biological and artificial agents.
