A developmental approach is adopted for this purpose. In particular, a humanoid robot is learning, through a self-exploration behaviour, the sensory consequences (in the visual domain) of self-generated movements. The generated sensorimotor experience is used as training data for a deep convolutional neural network that maps proprioceptive and motor data (e.g. initial arm joint positions and applied motor commands) onto the visual consequences of these actions. This forward model is then used in two experiments. First, for generating visual predictions of self-generated movements, which are compared to actual visual perceptions and then used to compute a prediction error. This error is shown to be higher when there is an external subject performing actions, compared to situations where the robot is observing only itself. This supports the idea that prediction errors may serve as a cue for distinguishing between self and other, a fundamental prerequisite for the sense of agency. Secondly, we show how predictions can be used to attenuate self-generated movements, and thus create enhanced visual perceptions, where the sight of objects - originally occluded by the robot body - is still maintained. This may represent an important tool both for cognitive development in robots and for the understanding of the sense of object permanence in humans.","PeriodicalId":236346,"journal":{"name":"2018 Joint IEEE 8th International Conference on Development and Learning and Epigenetic Robotics (ICDL-EpiRob)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129732790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In both humans and robots, such a representation is crucial to accurately control body movements. While humans learn and continuously adapt their body schema based on multimodal perception and neural plasticity, robots are typically assigned with a fixed analytical model (e.g., the robot kinematics) which describes their bodies. However, there are always discrepancies between a model and the real robot, and they vary over time, thus affecting the accuracy of movement control. In this work, we equip a humanoid robot with the ability to incrementally estimate such model inaccuracies by touching known planar surfaces (e.g., walls) in its vicinity through motor babbling exploration, effectively adapting its own body schema based on the contact information alone. The problem is formulated as an adaptive parameter estimation (Extended Kalman Filter) which makes use of planar constraints obtained at each contact detection. We compare different incremental update methods through an extensive set of experiments with a realistic simulation of the iCub humanoid robot, showing that the model inaccuracies can be reduced by more than 80%.","PeriodicalId":236346,"journal":{"name":"2018 Joint IEEE 8th International Conference on Development and Learning and Epigenetic Robotics (ICDL-EpiRob)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126919254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An important but less well-studied class of eye movements are so-called torsional eye movements, where the eyes rotate around the line of sight. In humans, such torsional eye movements obey certain lawful relationships such as Listing's Law. However, it is still an open question how these eye movements develop and what learning processes may contribute to their development. Here we propose a model of the development of torsional eye movements based on the active efficient coding (AEC) framework. AEC models the joint development of sensory encoding and movements of the sense organs to maximize the overall coding efficiency of the perceptual system. Our results demonstrate that optimizing coding efficiency in this way leads to torsional eye movements consistent with Listing's Law describing torsional eye movements in humans. This suggests that humanoid robots aiming to maximize the coding efficiency of their visual systems could also benefit from physical or simulated torsional eye movements.","PeriodicalId":236346,"journal":{"name":"2018 Joint IEEE 8th International Conference on Development and Learning and Epigenetic Robotics (ICDL-EpiRob)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132964540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is unclear how this capacity emerges and develops in biological systems. This paper presents an empirical study which investigates the development of novelty-based cognitive processes in the context of unstructured music-making activities in early childhood. We used principles of intuitive theories of emergence, the paradigm of overlapping waves of mechanisms of change and theories of music cognitive development to theoretically conceptualize the developmental process in the specific context. We applied the methodological principles of micro-genetic analysis for the development of an annotation scheme of micro-behaviors, which correspond to a set of cognitive processes. We took into consideration child's behavioral manifestations of music-induced affective engagement, as an indicator of intrinsic motivation. Our results suggest that the process of transition from spontaneous towards deliberate actions develops through exploratory actions, evaluation of the outcomes, reasoning and planning. The structure of these actions appears in the form of dynamic overlapping waves rather than in a linear or iterative manner. Additionally, our results indicate that children in early years make use of the affordances of the provided tools to scaffold their transition from concrete visual representation of sonic features towards abstract musical thinking, which suggests that musical development appears with the generative tension between action and symbol. Implications and future work are discussed regarding the development of intelligent robotic systems for user adaptive scaffolding of the observed mechanisms of change.","PeriodicalId":236346,"journal":{"name":"2018 Joint IEEE 8th International Conference on Development and Learning and Epigenetic Robotics (ICDL-EpiRob)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115811782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Word discovery and phoneme acquisition are known as important tasks in human child development. Human infants can discover words and phonemes from raw speech signals at eight months without any label data, unlike supervised learning-based speech recognition systems. NPB-DAA was proposed by Taniguchi et al. and shown to be able to perform simultaneous word and phoneme discovery without any label data. However, the computational cost of NPB-DAA was extremely large, and thus could not be applied to large-scale speech data. In this paper, we introduce lookup tables for conventional NPB-DAA to reduce the computational cost and developed an accelerated NPB-DAA. Using the lookup tables, values calculated in each subroutine are memorized and reused in the subsequent calculations. This acceleration does not harm the quality of word and phoneme discovery because the introduction of the lookup tables is theoretically supported. This paper also shows that our accelerated NPB-DAA significantly reduced the computational cost by 90% compared to conventional NPB-DAA.","PeriodicalId":236346,"journal":{"name":"2018 Joint IEEE 8th International Conference on Development and Learning and Epigenetic Robotics (ICDL-EpiRob)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121305519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Empirical evidence from developmental psychology suggests that a pivotal mechanism possibly driving open-ended learning is represented by action-outcome contingencies. Here we propose a specific hypothesis, expressed in the form of a blueprint cognitive architecture, that sketches the general mechanisms through which contingency-based open-ended learning might take place. According to this hypothesis, the matching (or distance) between a desired goal and the actual effect produced by the action can be used to drive the learning of both the motor skill used to accomplish the goal and the internal representation of the action outcome. We report here a computational model that implements the hypothesis and we illustrate two developmental psychology experiments related to the presented theory. Overall the model and experiments show the soundness of the hypothesis and represent a start towards validating it experimentally.","PeriodicalId":236346,"journal":{"name":"2018 Joint IEEE 8th International Conference on Development and Learning and Epigenetic Robotics (ICDL-EpiRob)","volume":"381 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122349769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The topic has been studied widely for decades. In the paper, with reference to the relevant mechanism of human, a novel strategy for developing robot reaching skill is proposed, in which the whole process is divided into two stages including rough reaching and iterative adjustment. Generally in the process of obtaining spatial information of target object, the accuracy of the absolute positioning might be severely affected due to inevitable errors derived from sensing means (e.g. camera) in real world scenario. On the contrary, the accuracy of relative positioning will be much better, in which we only require answering the relative location between the target and the end-effector. Under this view, the proposed method, called the relative-location based approximating strategy (RLA), firstly attempts to move the end-effector to the target roughly with a simple inverse model, and then gradually approximates to the target according to the information of the relative location, i.e. the direction of the target relative to the end-effector. To accomplish such an approximating process, an internal model regarding to base directions is developed, where the motor babbling is involved under the inspiration of infants development mechanism. The approach was experimentally validated using the child-sized physical humanoid robot PKU-HR6.0II in a completely autonomous style and the results illustrate the effectiveness and superiority of the proposed strategy.","PeriodicalId":236346,"journal":{"name":"2018 Joint IEEE 8th International Conference on Development and Learning and Epigenetic Robotics (ICDL-EpiRob)","volume":"320 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114205037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
