1. Han, D., Doya, K., & Tani, J. (2020). Goal-Directed Planning by Reinforcement Learning and Active Inference. arXiv preprint arXiv:2106.09938v2. LINK
   • We propose a novel computational framework of decision making with Bayesian inference, in which everything is integrated as an entire neural network model. The model learns to predict environmental state transitions by self-exploration and generating motor actions by sampling stochastic internal states z. Habitual behavior, which is obtained from the prior distribution of z, is acquired by reinforcement learning. Goal-directed behavior is determined from the posterior distribution of z by planning, using active inference which optimizes the past, current and future z by minimizing the variational free energy for the desired future observation constrained by the observed sensory sequence. We demonstrate the effectiveness of the proposed framework by experiments in a sensorimotor navigation task with camera observations and continuous motor actions.
2. Wirkuttis, N., & Tani, J. (2021).  Leading or Following? Dyadic Robot Imitative Interaction Using the Active Inference Framework. IEEE Robotics and Automation Letters, 6(3) 6024-6031. PDF
   • This study investigated how social interaction among robotic agents changes dynamically depending on individual sense of agency. The study examined how regulating the complexity term to minimize free energy during training determines the dynamic characteristics of networks and affects dyadic imitative interactions. Our experiment results show that through softer regulation of the complexity term, a robot with stronger agency develops and dominates its counterpart developed with weaker agency through tighter regulation.

   • This study shows how adequate goal-directed action plans of robots can be generated by developing synergy among visual attention, visual working memory, and executive control using active inference framework. In Particular, the study demonstrates that generalization capability in mentally manipulating unlearned objects can be significantly improved when two different visual working memories are used instead of a single visual working memory. The paper explains that such generalization can be achieved by developing the so-called "content-agnostic" information processing by allowing dynamic interaction between two visual working memories.

   • This study introduces PV-RNN, a novel variational RNN inspired by the predictive-coding ideas. The model learns to extract the probabilistic structures hidden in fluctuating temporal patterns by dynamically changing the stochasticity of its latent states. All three processes of learning, inference, and prediction are performed by maximizing the lower bound (equal to negative free energy) which is computed as the sum of the reconstruction error and the complexity term weighted by a regularization parameter, so-called meta-prior. A set of simulation studies on learning to predict complex fluctuated temporal patterns showed that the best generalization in learning can be achieved by setting meta-prior with an adequate intermediate value, whereas setting with larger or smaller values tends to develop deterministic chaos without generalization or more random process, respectively.

Learning to perceive the world as probabilistic or deterministic via interaction with others: a neuro-robotics experiment. IEEE Transactions on Neural Networks and Learning Systems, (4), 830-848. DOI: 10.1109/TNNLS.2015.2492140 PDF
   • This paper introduces a variational hierarchically-organized RNN model which inherits the dynamic property of the multiple timescale RNN (MTRNN). This model was applied to predictive coding and active inference of a humanoid robot which imitatively interacts with a human-operated robot. The experiment results showed that sensory driven behavior—based on probabilistic prediction—emerges when learning proceeds with the initial context state, as a random latent variable, to follow unit Gaussian. In contrast, intentional proactive behavior with deterministic prediction emerges when adaptation of the initial context state to a precise value is allowed during the learning.
6. Yamashita, Y., & Tani, J. (2008). Emergence of functional hierarchy in a multiple timescale neural network model: a humanoid robot experiment. PLoS Computational Biology, Vol.4, Issue.11, e1000220 PDF
   • This paper examines how functional hierarchy can self-organize through sensory-motor interactions, without assuming predefined level-structured functions. A humanoid robot was implemented with so-called the multipe timescales recurrent neural network (MTRNN). The MTRNN consists of the fast neurons part and the slow neurons one which are interconnected each other within a single network. The results of the robot learning experiments showed that functional hierarchy emerges with accompanying a compositional structure such that the continuous sensory-motor flow is segmented into reusable behavior primitives in the fast neurons part and those primitives are integrated into specified goal-directed actions in the slow neuron part.

   • This paper describes a possible mechanism of mirror neurons by using frameworks analogous to predictive coding and active inference. Forward predictive models (generative models) are learned for multiple goal-directed actions distributedly in a single RNN. In action generation, units called parametric bias (PB) play role of bifurcation parameter for the RNN dynamics to generate multiple goal-directed actions. On the other hand in recognizing actions, the best PB values to fit with perceived sensory sequences are inferred by minimizing the reconstruction error. A set of robotics experiments evaluate how generalization by learning can be achieved with this distributed representation scheme.

   • This paper introduces a predictive-coding-type RNN model of showing how continuous sensory-motor flow can be perceived as segmented into hierarchically organized primitives through anticipatory learning of local mixture of RNN experts with multiple levels. The study addresses the issue of how compositional representation can emerge solely through row sensory-motor experiences using a localist neural network model.
9. Tani, J. (1998). An interpretation of the ‘Self’ from the dynamical systems perspective: a constructivist approach. Journal of Consciousness Studies, 5(5/6), 516-542. PDF
   • This study attempts to describe the notion of the "self" from dynamical systems perspective based on our robot experiments using a multimodal predictive RNN model.  By investigating possible analogies between the experimental result and the phenomenological literature on the "self", we draw the conclusions that (1) the structure of the "self" corresponds to the "open dynamic structure" which is characterized by co-existence of stability in terms of goal-directedness and instability caused by embodiment; (2) the open dynamic structure causes the system's spontaneous transition to the unsteady phase where the "self" becomes aware.

    • This paper describes a neurorobotics experiment to show how 'symbolic structure' emerges as embedded in neuronal dynamics as the results of internalizing experiences of combinatorial sensory-motor interactions of robots. The action-sensation causality is learned as a forward model by using a Jordan-type recurrent neural net (RNN) which is implemented in a mobile robot. After the learning, the RNN generated on-line prediction of next sensation for given action as well as mental simulations for combinatorial action sequences without actual movements. Our dynamical system analysis showed that a finite state machine like symbolic structure emerges in a fractal-like global attractor of the RNN dynamics which is naturally situated with sensory-motor interactions with environment.

    • This paper describes how symbolic dynamics can be learned in RNN. A Jordan type RNN was trained with stochastic symbolic sequences with a grammar. The learning result showed that the stochastic symbolic sequences are reconstructed by self-organizing deterministic chaos in RNN.
