Developmental Machine Learning, Curiosity and Deep Reinforcement Learning
IEEE France Section's Life Members Affinity Group and French Chapter on Computational Intelligence IEEE is happy to invite you to join the lecture by Pierre-Yves Oudeyer.
Date and time: 2 March at 5:00PM
Abstract: Current approaches to AI and machine learning are still fundamentally limited in comparison with autonomous learning capabilities of children. What is remarkable is not that some children become world champions in certains games or specialties: it is rather their autonomy, flexibility and efficiency at learning many everyday skills under strongly limited resources of time, computation and energy. And they do not need the intervention of an engineer for each new task (e.g. they do not need someone to provide a new task specific reward function).
I will present a research program (Kaplan and Oudeyer, 2004; Oudeyer et al., 2007; Gottlieb and Oudeyer, 2019) that has focused on computational modeling of child development and learning mechanisms in the last decade. I will discuss several developmental forces that guide exploration in large real world spaces, starting from the perspective of how algorithmic models can help us understand better how they work in humans, and in return how this opens new approaches to autonomous machine learning.
In particular, I will discuss models of curiosity-driven autonomous learning, enabling machines to sample and explore their own goals and their own learning strategies, self-organizing a learning curriculum without any external reward or supervision. I will introduce the Intrinsically Motivated Goal Exploration Processes (IMGEPs-) algorithmic framework, and present two families of IMGEPs: population-based IMGEPs (Baranes and Oudeyer, 2013; Forestie et al.,2017) with learned goal spaces (Pere et al., 2018), which have allowed sample efficient learning learning of skill repertoires in real robots, and goal-conditioned Deep RL-based IMGEPs, which enable strong generalization properties when they are modular (Colas et al., 2019), in particular when leveraging the compositionality of language to imagine goals in curiosity-driven exploration (Colas et al., 2020).

Abstract: Recent advancement of image understanding with deep learning neural networks has brought great attraction to those in image analysis into the focus of deep learning networks. While researchers on video/image analysis have jumped on the bandwagon of deep learning networks, medical image analyzers would be the coming followers. The characteristics of medical images are extremely different from those of photos and video images. The application of medical image analysis is also much more critical. For achieving the best effectiveness and feasibility of medical image analysis with deep learning approaches, several issues have to be considered. In this talk we will give a brief overview of the development of neural networks for medical image analysis in the past and the future trends with deep learning. Several issues in regard of the data preparation, techniques, and clinic applications will also be discussed.

We are in the era of Artificial Intelligence (AI), in particular, Artificial Narrow Intelligence. AI has sailed through several “ ups and downs” and has come to the present state. At present we have been witnessing numerous success stories of AI, often beating human performance, and this has caused our expectation from AI to skyrocket. In many cases, neural networks (a major component of Computational Intelligence (CI)), in particular deep neural networks, recurrent neural networks, are the main pillars of such systems. Often AI systems ignore biological intelligence (BI). It seems, implicitly we have started believing in philosophies like “bigger the better” (bigger data sets or massive architecture with millions of free parameters) and “data say all”. Such approaches have been proved to be useful but raise some concerns too! In this talk I shall discuss, what in my personal view, are some important issues that need attention (Caveat: one can happily disagree and dissent). And if time permits, I shall briefly describe some of our attempts to “marginally address” some of these issues.

Understanding the decisions of a machine: interpretable and explainable AI
IEEE CIS Vice President for Technical Activities
Universidad Politecnica de Madrid, Spain
luis.magdalena [ at ] upm.es
Nowadays, our daily life is strongly conditioned by algorithmic decisions; decisions taken by machines that work on the basis of different AI techniques. Those decisions can even affect our fundamental rights, and consequently, it makes sense to analyse why they were taken. In fact, some recent regulations are considering this as a right, the "right to an explanation" when we are affected by one of these decisions. But in most cases, "deciphering" the reasons supporting an algorithmic decision is not a straightforward task. This is because many of the considered AI algorithms are black-box models.
The talk will consider this question and analyse different approaches that are applied when we need to understand the decision of a machine. These approaches go from the use of intrinsically interpretable models (as fuzzy rules or decision trees), to the superposition of explanation abilities over a model that was designed as a black-box.

Making sense out of activity sensing in eldercare
IEEE CIS Vice President for Publications
Electrical Engineering and Computer Science Department
University of Missouri-Columbia, USA
KellerJ [ at ] missouri.edu
With the increase in the population of older adults around the world, a significant amount of work has been done on in-home sensor technology to aid the elderly age independently. However, due to the large amounts of data generated by the sensors, it takes a lot of effort and time for the clinicians to makes sense of this data. In this talk, I will survey two connected approaches to provide explanations of these complex sensor patterns as they relate to senior health. Abnormal sensor patterns produced by certain resident behaviors could be linked to early signs of illness. In seven eldercare facilities around Columbia, MO operated by Americare, we have deployed an intelligent elderly monitoring system with summarization and symptom suggesting capabilities for 3 years.
The first procedure starts by identifying important attributes in the sensor data that are relevant to the health of the elderly. We then develop algorithms to extract these important health related features from the sensor parameters and summarize them in natural language, with methods grounded in fuzzy set theory. We focus on making the natural language summaries to be informative, accurate and concise, and have conducted numerous surveys of experts to validate our choices.
The second approach is a framework for detecting health patterns utilizing sensor sequence similarity and natural language processing (NLP). A context preserving representation of daily activities is used to measure the similarity between the sensor sequences of different days. The medical concepts are extracted from the nursing notes, and allow for imputation of potential reasons for health alerts based on the similarity. Joining these two approaches provide a powerful XAI description of early illness recognition for elders.

paestevez [ at ] gmail.com
Astronomy is facing a paradigm shift caused by the exponential growth of the sample size, data complexity and data generation rates of new sky surveys. To cope with a change of paradigm to data-driven science new computational intelligence approaches are needed. In this talk I will introduce the general context and the big data challenges that astronomy is facing. I will present the ALERCE broker, our state of the art project. Our pipeline includes an early classifier, a late classifier and an outlier detector. I will describe these three components and in particular some deep learning applications. The first application is the early detection of supernovae in astronomical images. We developed a convolutional neural network to discriminate between four types of transients and bogus events. This is implemented in an online platform called SNe Hunter, which is open to the general public. The second application is to classify different classes of astronomical objects based on a recurrent convolutional neural network, which uses directly sequences of images in an online fashion. The late classifier is using hierarchical random forests, and the outlier detector is based on geometric transformations.

The dangers of post-hoc interpretability: unjustified counterfactual explanations
LIP6, Paris, France
AXA, Paris, France
Over the recent years, the field of XAI (eXplainable AI) has gained phenomenal interest. In particular, post-hoc interpretability approaches have been proven to be powerful tools to generate explanations for the predictions made by a trained black-box model. However, they create the risk of having explanations that are a result of some artifacts learned by the model instead of actual knowledge from the data. In this presentation, we identify several issues that can arise in this context and that may be harmful for interpretability. In particular, we focus on the case of counterfactual explanations and asks whether the generated instances can be justified, i.e. continuously connected to some ground-truth data. We evaluate the risk of generating unjustified counterfactual examples by investigating the local neighborhoods of instances whose predictions are to be explained and show that this risk is quite high for several datasets. Furthermore, we show that most state of the art approaches do not differentiate justified from unjustified counterfactual examples, leading to less useful explanations.

Semantic segmentation is a key problem for many computer vision tasks. While approaches based on convolutional neural networks constantly break new records on different benchmarks, generalizing well to diverse testing environments remains a major challenge. In numerous real world applications, there is indeed a large gap between data distributions in train and test domains, which results in severe performance loss at run-time. In this talk, we address the task of unsupervised domain adaptation in semantic segmentation. We illustrate the strategies with two synthetic-2-real street-view image set-ups.

An Overview of Evolutionary Multi-Objective Optimization
Carlos A. Coello Coello
IEEE CIS Vice President for Member Activities
Mexico City, México
ccoello [ at ] cs.cinvestav.mx
Multi-objective optimization refers to solving problems having two or more (often conflicting) objectives at the same time. Such problems are ill-defined and their solution is not a single solution but instead, a set of them, which represent the best possible trade-offs among the objectives.
Evolutionary algorithms are particularly suitable for solving multi-objective problems because they are population-based, and require little domain-specific information to conduct the search. Due to these advantages, the development of the so-called multi-objective evolutionary algorithms (MOEAs) has significantly increased in the last 15 years.
In this talk, we will provide a general overview of the field, including the main algorithms in current use as well as some of the many applications of them.
Carlos Artemio Coello Coello received a PhD in Computer Science from Tulane University (USA) in 1996. His research has mainly focused on the design of new multi-objective optimization algorithms based on bio-inspired metaheuristics, which is an area in which he has made pioneering contributions. He currently has over 500 publications which, according to Google Scholar, report over 48,500 citations (with an h-index of 86).
He is the recipient of the prestigious 2013 IEEE Kiyo Tomiyasu Award, "for pioneering contributions to single- and multiobjective optimization techniques using bioinspired metaheuristics" and of the 2016 The World Academy of Sciences (TWAS) Award in "Engineering Sciences". Since January 2011, he is an IEEE Fellow. He is also Associate Editor of several international journals including the IEEE Transactions on Evolutionary Computation, Evolutionary Computation and the IEEE Transactions on Emerging Topics in Computational Intelligence.
He is currently Vice President for Member Activities of the IEEE Computational Intelligence Society (CIS), and Full Professor with distinction at the Computer Science Department of CINVESTAV-IPN in Mexico City, Mexico.
Introduction to Quantum-Inspired Evolutionary Algorithms and their Application to Neural Architecture Search

marley [ at ] ele.puc-rio.br
Quantum-inspired evolutionary algorithms can be considered a new class of evolutionary computation algorithms, inspired by quantum computing principles, that has been developed to achieve better performance in computationally intensive problems. In some applications, time taken to calculate the evaluation function may be critical. In those cases, reaching good solutions with the smallest possible number of evaluations is a very important factor. These quantum-inspired evolutionary models provide good (or optimal) solutions with a smaller number of evaluations, being adequate to solve optimization problems where the evaluation of each possible solution is computationally expensive. One important computationally expensive problem is the automatic configuration of a neural network, which, in the deep learning context is known as Neural Architecture Search.
In this talk we will present an overview of quantum-inspired evolutionary algorithms and their application to the evolution of different neural network models, focusing in the neural architecture search of Convolutional Neural Networks.

Evolutionary Game AI

simon.lucas [ at ] QMUL.AC.UK
Evolutionary algorithms can be applied in a number of useful ways to create intelligent game playing agents or to evolve or tune new games. In this talk I’ll explain how they can be used for game-playing agents, which falls into three distinct categories: rolling horizon evolution, policy evolution and hyper-parameter tuning. Rolling horizon evolution is a type of statistical forward planning algorithm that can be used as a direct alternative to Monte Carlo Tree Search, and often outperforms MCTS for video game AI. Note, in RL this process of searching for the best available action at each step is sometimes called Transient or Short-Term Learning; these methods require a fast and easily copied forward model of the game or simulation, but provide instant intelligent behaviour across a range of games. Policy evolution refers to directly evolving the parameters of a game-playing agent (for example, evolving the weights of a neural network). Learned policies can be combined with statistical forward planning algorithms to provide even higher standards of play. Finally, the hyper-parameters of these systems can be efficiently tuned using model-based evolutionary algorithms, such as the N-Tuple Bandit Evolutionary Algorithm. Model-based evolution often provide a significant boost in sample efficiency. In the talk I’ll demonstrate these algorithms in action on a number of games.
Simon Lucas is a professor of Artificial Intelligence and Head of the School of Electronic Engineering and Computer Science at Queen Mary University of London where he also heads the Game AI Research Group. He holds a PhD degree (1991) in Electronics and Computer Science from the University of Southampton.

Reinforcement Learning of Strategies for General Game
Associate Professor at Sorbonne Université
LIP6, Paris, France
jean-noel.vittaut [ at ] lip6.fr
General Game Playing (GGP) is a domain of Artificial Intelligence (AI) aiming at developing autonomous agents which are able to play a large variety of games, called General Games. GGP is different from search algorithms because it allows to play specific games at a good level and opens the possibility to evaluate the efficiency of AI methods with no prior knowledge from experts.
An important aspect of our work lies in the utilization of an implicit game-tree representation as a set of logic rules, an explicit representation being too large to be stored in memory. In this context, we have proposed an efficient method of rule instantiation which allows the computation of a logic circuit making it possible to perform static and dynamic analyses of the game and simulate random matches more efficiently. By using Monte-Carlo Tree Search methods, we can learn strategies which we can start to use within time budgets compatible with human reflexion time.
Jean-Noël Vittaut has been an associate professor at the Computer Science Laboratory (LIP6) of Sorbonne University since 2019. He was previously a lecturer at Vincennes-Saint-Denis University and defended his PhD on General Game Playing (GGP) in 2017.

He has also developed a programme called LeJoueur which has won an international GGP competition.
Interval-valued non-additive image processing
Associate Professor at Montpellier University
LIRMM, Montpellier, France
strauss [ at ] lirmm.fr
Digital image processing consists of imitating continuous image processing such as contrast enhancement, restoration, rotation, denoising, etc. via an algorithm. These kinds of algorithms are constructed in such a way that the produced image resembles the 'digitalizing' of an image having undergone the imitated continuous process, as much as possible. For example, when a digital image is 'rotated', the idea is to create the digital image that one would have obtained by rotating the camera before shooting.
Most of these algorithms can be considered as linear aggregation processes, involving weighted sums. However, there is no single way to make an algorithm that mimics continuous image processing: each continuous process corresponds to an infinity of digital processes leading to an infinity of digital images. Each of these can be seen as the digitisation of the image having undergone the mimicked continuous process.
In recent work, we have shown that, by replacing the linear aggregation by an aggregation involving a fuzzy integral, it is possible to represent the convex set of this infinity of images. In this talk, we propose to present quickly the principle of digital image processing and its generalisation by fuzzy integrals.
Olivier Strauss received his Ph.D. in signal processing and systems in 1992 from the Montpellier University of Science, France. Since 1992 he has served as associate professor in the same University and researcher in the ICAR team (image and interaction) of the LIRMM (Laboratory of Informatics, Robotics and Microelectronic of Montpellier). His main research areas are image processing and vision. He has also a strong interest in sampling, epistemic statistics, imprecise probabilities and fuzzy sets.

The events will take place at: LIP6, room 105 (1st floor), corridor 25-26, 4 place Jussieu, 75005 Paris.
Abstract: Decomposable Graphical Models are of high relevance for complex industrial applications. The Markov network approach is one of their most prominent representatives and an important tool to decompose uncertain knowledge in high dimensional domains. But also relational and possibilistic decompositions turn out to be useful to make reasoning in such domains feasible. Compared to conditioning a decomposable model on given evidence, the learning of the structure of the model from data as well as the fusion of several decomposable models is much more complicated. The important belief change operation revision has been almost entirely disregarded in the past, although the problem of inconsistencies is of utmost relevance for real world applications. In this talk these problems are addressed by presenting several successful complex industrial applications.

Abstract: Astronomy is facing a paradigm shift caused by the exponential growth of the sample size, data complexity and data generation rates of new sky surveys. To cope with a change of paradigm to data-driven science new computational intelligence, machine learning and statistical approaches are needed. In this talk I will present two main applications. The first is to discriminate periodic versus non-periodic light curves, and then estimate the period of the periodic ones. Light curves are one-dimensional time series of the brightness of a star versus time. We have developed several methods based on the correntropy function (generalized correlation using information theoretical learning concepts), which outperforms conventional approaches. Results using 32.8 million light curves will be presented. Interestingly, some of these techniques can be applied to other problems such as sleep EEG analysis, and I will present preliminary results on this topic too.
The second application is the automated real-time transient detection in astronomical images. The aim is to achieve real-time detection of supernovae and other transients with the Dark Energy Camera. A novel transient detection pipeline was developed. We have been applying convolutional neural nets (deep learning) to discriminate between true transients and bogus transients, among other techniques, e.g non-negative matrix factorization combined with random forests. Results using 1.5 million images will be presented. The new pipeline was successfully tested online in February 2015 finding more than 100 supernovae in a few days of telescope observation.

Abstract: Multi-Criteria aggregation is a pervasive problem appearing in many technological domains. During this presentation, we shall discuss some issues related to this task. One issue is the modeling of multi-criteria decision functions and a related issue is the evaluation of these decision functions in the face of uncertain information. One case we shall consider is the evaluation of the OWA operator when the satisfaction to the individual criteria is expressed via a probability distribution. We shall also consider the case of interval criteria satisfactions. We shall look at the role of fuzzy measures in the modeling process. One issue that must be dealt with is the ordering of the complex uncertain criteria satisfactions that is required to use the Choquet integral in the criteria aggregation.

Ensemble Approaches in Learning
by Xin Yao, Professor at the University of Birmingham (UK), President of the IEEE Computational Intelligence Society
Venue: room 105, corridor 25-26, 4 place Jussieu, 75005 Paris
Designing a monolithic system for a large and complex learning task is hard. Divide-and-conquer is a common strategy in tackling such large and complex problems. Ensembles can be regarded an automatic approach towards automatic divide-and-conquer. Many ensemble methods, including boosting, bagging,
negative correlation, etc., have been used in machine learning and data mining for many years. This talk will describe three examples of ensemble methods,
i.e., multi-objective learning, online learning with concept drift, and multi-class imbalance learning. Given the important role of diversity in ensemble methods, some discussions and analyses will be given to gain a better understanding of how and when diversity may help ensemble learning.
Some materials used in the talk are based on the following papers:

algorithms,'' Journal of Mathematical Modelling and Algorithms, 5(4):417-445,

We are pleased to announce that, on the 28th of May 2015, Prof. Jim Keller, of the University of Missouri, USA, will give a talk entitled "Does it all add up? A study of fuzzy protoform linguistic summarization of time series", sponsored by the Computational Intelligence Society under its Distinguished Lecturer Program. The abstract for this talk is:
Producing linguistic summaries of large databases or temporal sequences of measurements is an endeavor that is receiving increased attention. These summaries can be used in a continuous monitoring situation, like eldercare, where it is important to ascertain if the current summaries represent an abnormal condition. Primarily a human, such as a care giver in the eldercare
example, is the recipient of the set of summaries describing a time range, for example, last night’s activities. However, as the number of sensors and monitored conditions grow, sorting through a fairly large number of summaries can be a burden for the person, i.e., the summaries stop being information and become yet one more pile of data. It is therefore necessary to automatically process sets of summaries to condense the data into more manageable chunks.
The first step towards automatically comparing sets of digests is to determine similarity. For fuzzy protoform based summaries, we developed a natural similarity and proved that the associated dissimilarity is a metric over the space of protoforms. Utilizing that distance measure, we defined and examined several fuzzy set methods to compute dissimilarity between sets of summaries, and most recently utilized these measures to define prototypical behavior over a large number of normal time periods.
In this talk, I will cover the definition of fuzzy protoforms, define our (dis)similarity, outline the proof that it is a metric, discuss the fuzzy aggregation methods for sets of summaries, and show how prototypes are formed and can used to detect abnormal nights. The talk will be loaded with actual examples from our eldercare research. There is much work to be done and hopefully, more questions than answers will result from the discussion.

ents is here.
