    Inspired by the work on sensory substitution which shows the technical and practical possibilities for perceptual learning, we have carried out a global longitudinal study of the learning capacities for reading digital graphical objects by four blind high-school students. We report here the results obtained with the Tactos system during certain phases of this study, in particular the acquisition o... View full abstract»

    Demonstration learning is a powerful and practical technique to develop robot behaviors. Even so, development remains a challenge and possible demonstration limitations can degrade policy performance. This work presents an approach for policy improvement and adaptation through a tactile interface located on the body of a robot. We introduce the Tactile Policy Correction (TPC) algorithm, that emplo... View full abstract»

    Acquiring concepts from experience is a key aspect of development and one that is commonly neglected in learning agents. In this work, concept acquisition is formulated as an unsupervised learning problem and is addressed with a novel algorithm: kx-trees. kx-trees differ from prior approaches to unsupervised learning in that they require very little information; four user selected parameters deter...

    This article presents a mechanism for the early development of imitation through a simulation of infant-caregiver interaction. A model was created to acquire a body mapping (a mapping from observed body motions to motor commands), which is necessary for imitation, while discriminating self-motion from the motion of the other. The simulation results show that the development of a body mapping depen... View full abstract»

    In this paper we present a computational model for incremental word meaning acquisition. It is designed to rapidly build category representations which correspond to the meaning of words. In contrast to existing approaches, our model further extracts word meaning-relevant features using a statistical learning technique. Both category learning and feature extraction are performed simultaneously. To... View full abstract»

    Psychological research has demonstrated that subjects shown animations consisting of nothing more than simple geometric shapes perceive the shapes as being alive, having goals and intentions, and even engaging in social activities such as chasing and evading one another. While the subjects could not directly perceive affective state, motor commands, or the beliefs and intentions of the actors in t... View full abstract»

    An intelligent agent, embedded in the physical world, will receive a high-dimensional ongoing stream of low-level sensory input. In order to understand and manipulate the world, the agent must be capable of learning high-level concepts. Object is one such concept. We are developing the Object Semantic Hierarchy (OSH), which consists of multiple representations with different ontologies. The OSH fa... View full abstract»

    In this paper we investigate a computational model of word learning, that is embedded in a cognitively and ecologically plausible framework. Multi-modal stimuli from four different speakers form a varied source of experience. The model incorporates active learning, attention to a communicative setting and clarity of the visual scene. The model's ability to learn associations between speech utteran... View full abstract»

    It has been a puzzle how the syntax of natural language could be learned from positive evidence alone. Here we present a hybrid neural-network model in which artificial syntactic categories are acquired through unsupervised competitive learning due to grouping together lexical words with consistent phonological endings. These relatively large syntactic categories then become target signals for a f... View full abstract»

  • Using information gain to build meaningful decision forests for multilabel classification

    “Gain-Based Separation” is a novel heuristic that modifies the standard multiclass decision tree learning algorithm to produce forests that can describe an example or object with multiple classifications. When the information gain at a node would be higher if all examples of a particular classification were removed, those examples are reserved for another tree. In this way, the algor...

    In this paper we address the question of how closely everyday human teachers match a theoretically optimal teacher. We present two experiments in which subjects teach a concept to our robot in a supervised fashion. In the first experiment we give subjects no instructions on teaching and observe how they teach naturally as compared to an optimal strategy. We find that people are suboptimal in sever...

    How can autonomous agents with access to only their own sensory-motor experiences learn to look at visual targets? We explore this seemingly simple question, and find that naïve approaches are surprisingly brittle. Digging deeper, we show that learning to look at visual targets contains a deep, rich problem structure, relating sensory experience, motor experience, and development. By captu...

  • Developing feedback: How children of different age contribute to a tutoring interaction with adults

    Learning is a social and interactional endeavor, in which the learner generally receives support from his/her social environment. In this process, the learner's feedback is important as it provides information about the learner's current understanding which, in turn, enables the tutor to adjust his/her presentation accordingly. Thus, through their feedback learners can actively shape the tutor's p... View full abstract»

    Recent progresses of ultrasound imaging technology have led observations of fetal intrauterine behavior and a perspective of intrauterine learning. Understanding fetal behavior in uterus is important for medical cares for prenatal infants, because the intervention like “nesting” or “swaddling” in NICU (Neonatal Intensive Care Unit) is based on a perspective of intrauter...

  • Distribution of object types of “light” and “heavy” early-learned English verbs

    In the developmental psycholinguistic literature, it is common to distinguish verbs that are semantically light from those that are not. One important reason is that the light verbs (take, get, make, do, go, etc.) - excellent substitutes for specific verbs and very frequent in adult speech to children - are thought to help children learn the verb system. Although quantitative and qualitative crite... View full abstract»

    We study three types of learning with Bayesian agent-based modeling. First, we show that previous results obtained from learning chains can be generalized to a more realistic lattice world involving multiple social interactions. Learning based on the passing of posterior probabilities converges to the truth more quickly and reliably than does learning based on imitation and sampling from the envir... View full abstract»

    We treat information gathering as a POMDP in which the goal is to maximize an accumulated intrinsic reward at each time step based on the negative entropy of the agent's beliefs about the world state. We show that such information foraging agents can discover intelligent exploration policies that take into account the long-term effects of sensor and motor actions, and can automatically adapt to va...

    Even seemingly simple reaching task requires complex integration or remapping of reference frames with respect to eye, head and hand. Head-centered reference frame and head movement may play important roles in natural tasks and in the development of reaching. To understand the underlying control mechanism that support smooth reaching in particular and the seamless coordination of head and hand mov... View full abstract»
