@article{Martinez2018,\nabstract = {{\\textcopyright} 2018 World Scientific Publishing Company Many robotic control architectures perform a continuous cycle of sensing, reasoning and acting, where that reasoning can be carried out in a reactive or deliberative form. Reactive methods are fast and provide the robot with high interaction and response capabilities. Deliberative reasoning is particularly suitable in robotic systems because it employs some form of forward projection (reasoning in depth about goals, pre-conditions, resources and timing constraints) and provides the robot reasonable responses in situations unforeseen by the designer. However, this reasoning, typically conducted using Artificial Intelligence techniques like Automated Planning (AP), is not effective for controlling autonomous agents which operate in complex and dynamic environments. Deliberative planning, although feasible in stable situations, takes too long in unexpected or changing situations which require re-planning. Therefore, planning cannot be done on-line in many complex robotic problems, where quick responses are frequently required. In this paper, we propose an alternative approach based on case-based policy learning which integrates deliberative reasoning through AP and reactive response time through reactive planning policies. The method is based on learning planning knowledge from actual experiences to obtain a case-based policy. The contribution of this paper is two fold. First, it is shown that the learned case-based policy produces reasonable and timely responses in complex environments. Second, it is also shown how one case-based policy that solves a particular problem can be reused to solve a similar but more complex problem in a transfer learning scope.},\nauthor = {Mart{\\'{i}}nez, M. and Garc{\\'{i}}a, J. and Fern{\\'{a}}ndez, F.},\ndoi = {10.1142/S0219622018500086},\nissn = {02196220},\njournal = {International Journal of Information Technology and Decision Making},\nkeywords = {Automated planning,case-base reasoning,control systems,planning and execution,robotics},\ntitle = {{On-Line Case-Based Policy Learning for Automated Planning in Probabilistic Environments}},\nyear = {2018}\n}\n

We have used three main axes to organize the article's contents: pedestrian models, validation techniques, and multiscale approaches. The backbone of this work is the classification of existing pedestrian models; we have organized the works in the literature under five categories, according to the techniques used for implementing the operational level in each pedestrian model.

Furthermore, we review the key issues that arise when facing multiscale pedestrian modeling, where we first focus on the behavioral scale (combinations of micro and macro pedestrian models) and second on the scale size (from individuals to crowds).

@article{Martinez-Gil2017,\nabstract = {{\\textcopyright} 2017This paper analyzes the emergent behaviors of pedestrian groups that learn through the multiagent reinforcement learning model developed in our group. Five scenarios studied in the pedestrian model literature, and with different levels of complexity, were simulated in order to analyze the robustness and the scalability of the model. Firstly, a reduced group of agents must learn by interaction with the environment in each scenario. In this phase, each agent learns its own kinematic controller, that will drive it at a simulation time. Secondly, the number of simulated agents is increased, in each scenario where agents have previously learnt, to test the appearance of emergent macroscopic behaviors without additional learning. This strategy allows us to evaluate the robustness and the consistency and quality of the learned behaviors. For this purpose several tools from pedestrian dynamics, such as fundamental diagrams and density maps, are used. The results reveal that the developed model is capable of simulating human-like micro and macro pedestrian behaviors for the simulation scenarios studied, including those where the number of pedestrians has been scaled by one order of magnitude with respect to the situation learned.},\nauthor = {Martinez-Gil, Francisco and Lozano, Miguel and Fern{\\'{a}}ndez, Fernando},\ndoi = {10.1016/j.simpat.2017.03.003},\nfile = {:home/fernando/papers/tmp/1-s2.0-S1569190X17300503-main.pdf:pdf},\nissn = {1569190X},\njournal = {Simulation Modelling Practice and Theory},\nkeywords = {Behavioural simulation,Emergent behaviours,Multi-Agent Reinforcement Learning (MARL),Pedestrian simulation and modeling},\nmonth = {may},\npages = {117--133},\ntitle = {{Emergent behaviors and scalability for multi-agent reinforcement learning-based pedestrian models}},\nurl = {http://linkinghub.elsevier.com/retrieve/pii/S1569190X17300503},\nvolume = {74},\nyear = {2017}\n}\n

@article{Martinez2016,\nabstract = {{\\textcopyright} 2016 Elsevier B.V.Generating sequences of actions-plans-for robots using Automated Planning in stochastic and dynamic environments has been shown to be a difficult task with high computational complexity. These plans are composed of actions whose execution might fail due to different reasons. In many cases, if the execution of an action fails, it prevents the execution of some (or all) of the remainder actions in the plan. Therefore, in most real-world scenarios computing a complete and sound (valid) plan at each (re-)planning step is not worth the computational resources and time required to generate the plan. This is specially true given the high probability of plan execution failure. Besides, in many real-world environments, plans must be generated fast, both at the start of the execution and after every execution failure. In this paper, we present Variable Resolution Planning which uses Automated Planning to quickly compute a reasonable (not necessarily sound) plan. Our approach computes an abstract representation-removing some information from the planning task-which is used once a search depth of k steps has been reached. Thus, our approach generates a plan where the first k actions are applicable if the domain is stationary and deterministic, while the rest of the plan might not be necessarily applicable. The advantages of this approach are that it: is faster than regular full-fledged planning (both in the probabilistic or deterministic settings); does not spend much time on the far future actions that probably will not be executed, since in most cases it will need to replan before executing the end of the plan; and takes into account some information of the far future, as an improvement over pure reactive systems.

@incollection{Martinez-Gil2015,\nabstract = {{\\textcopyright} Springer International Publishing Switzerland 2015.In this work, a Multi-agent Reinforcement Learning framework is used to generate simulations of virtual pedestrians groups. The aim is to study the influence of two different learning approaches in the quality of generated simulations. The case of study consists on the simulation of the crossing of two groups of embodied virtual agents inside a narrow corridor. This scenario is a classic experiment inside the pedestrian modeling area, because a collective behavior, specifically the lanes formation, emerges with real pedestrians. The paper studies the influence of different learning algorithms, function approximation approaches, and knowledge transfer mechanisms on performance of learned pedestrian behaviors.

Results demonstrate empirically that our RL framework generates individual behaviors capable of emerging the expected collective behavior as occurred in real pedestrians.

@article{Martinez-Gil2015a,\nabstract = {{\\textcopyright} 2014, The Author(s).In this paper, a new multi-agent reinforcement learning approach is introduced for the simulation of pedestrian groups.

The embodied agents must learn to control their velocity, avoiding obstacles and the other pedestrians, to reach a goal inside the scenario. The main contribution of this paper is to propose this new methodology that uses different iterative learning strategies, combining a vector quantization (state space generalization) with the Q-learning algorithm (VQQL). Two algorithmic schemas, Iterative VQQL and Incremental, which differ in the way of addressing the problems, have been designed and used with and without transfer of knowledge. These algorithms are tested and compared with the VQQL algorithm as a baseline in two scenarios where agents need to solve well-known problems in pedestrian modeling. In the first, agents in a closed room need to reach the unique exit producing and solving a bottleneck. In in the second, two groups of agents inside a corridor need to reach their goal that is placed in opposite sides (they need to solve the crossing). In the first scenario, we focus on scalability, use metrics from the pedestrian modeling field, and compare with the Helbing's social force model. The emergence of collective behaviors, that is, the shell-shaped clogging in front of the exit in the first scenario, and the lane formation as a solution to the problem of the crossing, have been obtained and analyzed.

The competition is typically organized every two years and deals with relevant issues for the community such as the definition of evaluation standards, the publication of benchmarks and the collection and dissemination of data about state-of-the-art planners. This paper focuses on the deterministic part, the longest-running part of the International Planning Competition. The paper describes its format, the participants, the selection of benchmarks and the generated results accompanied with analysis from different perspectives. The paper also examines the results of a brand new track created to explore the potential of planners that exploit the power of multi-core processors. Overall, the results of the competition indicate significant progress with respect to previous competitions, but they also reveal that some issues remain open and need further research, such as the coverage of temporal planners when concurrency is required and the performance in the multi-core track. As a novelty, all the data and the software generated for running the competition have been made publicly available allowing researchers to reproduce the competition and to carry out different analysis of the results.\n

@article{Calderita2014,\nabstract = {Neurorehabilitation therapies exploiting the use-dependent plasticity of our neuromuscular system are devised to help patients who suffer from injuries or diseases of this system. These therapies take advantage of the fact that the motor activity alters the properties of our neurons and muscles, including the pattern of their connectivity, and thus their functionality. Hence, a sensor-motor treatment where patients makes certain movements will help them (re)learn how to move the affected body parts. But these traditional rehabilitation processes are usually repetitive and lengthy, reducing motivation and adherence to the treatment, and thus limiting the benefits for the patients. Objective: Our goal was to create innovative neurorehabilitation therapies based on THERAPIST, a socially assistive robot. THERAPIST is an autonomous robot that is able to find and execute plans and adapt them to new situations in real-time. The software architecture of THERAPIST monitors and determines the course of action, learns from previous experiences, and interacts with people using verbal and non-verbal channels. THERAPIST can increase the adherence of the patient to the sessions using serious games. Data are recorded and can be used to tailor patient sessions. Methods: We hypothesized that pediatric patients would engage better in a therapeutic non-physical interaction with a robot, facilitating the design of new therapies to improve patient motivation. We propose RoboCog, a novel cognitive architecture. This architecture will enhance the effectiveness and time-of-response of complex multi-degree-of-freedom robots designed to collaborate with humans, combining two core elements: a deep and hybrid representation of the current state, own, and observed; and a set of task-dependent planners, working at different levels of abstraction but connected to this central representation through a common interface. Using RoboCog, THERAPIST engages the human partner in an active interactive process. But RoboCog also endows the robot with abilities for high-level planning, monitoring, and learning. Thus, THERAPIST engages the patient through different games or activities, and adapts the session to each individual. Results: RoboCog successfully integrates a deliberative planner with a set of modules working at situational or sensorimotor levels. This architecture also allows THERAPIST to deliver responses at a human rate. The synchronization of the multiple interaction modalities results from a unique scene representation or model. THERAPIST is now a socially interactive robot that, instead of reproducing the phrases or gestures that the developers decide, maintains a dialogue and autonomously generate gestures or expressions. THERAPIST is able to play simple games with human partners, which requires humans to perform certain movements, and also to capture the human motion, for later analysis by clinic specialists. Conclusions: The initial hypothesis was validated by our experimental studies showing that interaction with the robot results in highly attentive and collaborative attitudes in pediatric patients. We also verified that RoboCog allows the robot to interact with patients at human rates. However, there remain many issues to overcome. The development of novel hands-off rehabilitation therapies will require the intersection of multiple challenging directions of research that we are currently exploring.},\nauthor = {Calderita, L.V. and Manso, L.J. and Bustos, P. and Su{\\'{a}}rez-Mej{\\'{i}}as, C. and Fern{\\'{a}}ndez, F. and Bandera, A.},\ndoi = {10.2196/rehab.3151},\nissn = {14388871},\njournal = {JMIR Rehabilitation and Assistive Technologies},\nkeywords = {Cognitive robotics,Interactive games,Rehabilitation},\nnumber = {1},\ntitle = {{THERAPIST:Towards an autonomous socially interactive robot for motor and neurorehabilitation therapies for children}},\nurl = {https://rehab.jmir.org/2014/1/e1/},\nvolume = {1},\nyear = {2014}\n}\n

@inproceedings{Gonzalez-Quijano2012,\nabstract = {Robot motor control learning is currently one of the most active research areas in robotics. Many learning techniques have been developed for relatively simple problems. However, very few of them have direct applicability in complex robotic systems without assuming prior knowledge about the task, mainly due to three facts. Firstly, they scale badly to continues and high dimensional problems. Secondly, they need too many real robot-environment interactions.

\n Robot motor control learning is currently one of the most active research areas in robotics. Many learning techniques have been developed for relatively simple problems. However, very few of them have direct applicability in complex robotic systems without assuming prior knowledge about the task, mainly due to three facts. Firstly, they scale badly to continues and high dimensional problems. Secondly, they need too many real robot-environment interactions. Finally, they are not capable of adapting to environment or robot dynamic changes. In order to overcome these problems, we have developed a new algorithm capable of finding from scratch open-loop state-action trajectory solutions by mixing sample-based tree kinodynamic planning with dynamic model learning. Some results demonstrating the viability of this new type of approach in the cart-pole swing-up task problem are presented. © 2012 IEEE.\n

@article{Fernandez2008a,\nabstract = {The distance metric is the corner stone of nearest neighbor (NN)-based methods, and therefore, of nearest prototype (NP) algorithms. That is because they classify depending on the similarity of the data. When the data is characterized by a set of features which may contribute to the classification task in different levels, feature weighting or selection is required, sometimes in a local sense. However, local weighting is typically restricted to NN approaches. In this paper, we introduce local feature weighting (LFW) in NP classification. LFW provides each prototype its own weight vector, opposite to typical global weighting methods found in the NP literature, where all the prototypes share the same one. Providing each prototype its own weight vector has a novel effect in the borders of the Voronoi regions generated: They become nonlinear. We have integrated LFW with a previously developed evolutionary nearest prototype classifier (ENPC). The experiments performed both in artificial and real data sets demonstrate that the resulting algorithm that we call LFW in nearest prototype classification (LFW-NPC) avoids overfitting on training data in domains where the features may have different contribution to the classification task in different areas of the feature space. This generalization capability is also reflected in automatically obtaining an accurate and reduced set of prototypes. {\\textcopyright} 2007 IEEE.},\nauthor = {Fernandez, F. and Isasi, P.},\ndoi = {10.1109/TNN.2007.902955},\nfile = {:home/fernando/papers/tmp/04359199.pdf:pdf},\nissn = {1045-9227},\njournal = {IEEE Transactions on Neural Networks},\nkeywords = {Evolutionary learning,Local feature weighting (LFW),Nearest prototype (NP) classification,Weighted Euclidean distance},\nmonth = {jan},\nnumber = {1},\npages = {40--53},\ntitle = {{Local Feature Weighting in Nearest Prototype Classification}},\nurl = {http://ieeexplore.ieee.org/document/4359199/},\nvolume = {19},\nyear = {2008}\n}\n

That is because they classify depending on the similarity of the data. When the data is characterized by a set of features which may contribute to the classification task in different levels, feature weighting or selection is required, sometimes in a local sense. However, local weighting is typically restricted to NN approaches. In this paper, we introduce local feature weighting (LFW) in NP classification. LFW provides each prototype its own weight vector, opposite to typical global weighting methods found in the NP literature, where all the prototypes share the same one. Providing each prototype its own weight vector has a novel effect in the borders of the Voronoi regions generated: They become nonlinear. We have integrated LFW with a previously developed evolutionary nearest prototype classifier (ENPC). The experiments performed both in artificial and real data sets demonstrate that the resulting algorithm that we call LFW in nearest prototype classification (LFW-NPC) avoids overfitting on training data in domains where the features may have different contribution to the classification task in different areas of the feature space. This generalization capability is also reflected in automatically obtaining an accurate and reduced set of prototypes. © 2007 IEEE.\n

@article{Fernandez2008b,\nabstract = {When applying reinforcement learning in domains with very large or continuous state spaces, the experience obtained by the learning agent in the interaction with the environment must be generalized. The generalization methods are usually based on the approximation of the value functions used to compute the action policy and tackled in two different ways.

@article{Camacho2006,\nabstract = {SkeletonAgent is an agent framework whose main feature is to integrate different artificial intelligent skills, like planning or learning, to obtain new behaviours in a multi-agent environment.

\n SkeletonAgent is an agent framework whose main feature is to integrate different artificial intelligent skills, like planning or learning, to obtain new behaviours in a multi-agent environment. This framework has been previously instantiated in a deliberative domain (electronic tourism), where planning was used to integrate Web information in a tourist plan. RoboSkeleton results from the instantiation of the same framework, SkeletonAgent, in a very different domain, the robot soccer. This paper shows how this architecture is used to obtain collaborative behaviours in a reactive domain. The paper describes how the different modules of the architecture for the robot soccer agents are designed, directly showing the flexibility of our framework. © 2005 Elsevier Ltd.
