Abstract : Deep learning is undergoing rapid development thanks to the increasing power of computing resources and the design of new neural network architectures. These architectures are being applied with success across various fields. Data, originating from diverse fields, is abundant, heterogeneous and often unlabeled. Consequently, a plethora of learning algorithms has been devised to cater to different data types. Conventional clustering algorithms have shown their limitations as they are directly applied to raw data, or even with a "shallow" transformation. Unlike classical approaches, deep clustering architectures are specifically adapted to capture the complex structures present in data. This is due to their ability to merge the fundamental concepts of clustering with the capacity of deep neural networks to discover underlying structures and produce efficient class representations. The tutorial presents our contribution to the deep clustering of attributed graphs data based on Graph Convolutional Networks (GCNs). Initially formulated within the semi-supervised context, we have adapted it for unsupervised context. To achieve this, we have devised a novel learning framework that hinges on three complementary loss functions. The first uses node attributes by adapting a kernel k-means loss function. The second uses connectivity information between the nodes in the graph. The third uses graph reconstruction from the network output. Furthermore, unlike most algorithms which assume that the graph is initially given, we propose a new structure by adaptively merging two graphs: the graph associated with the original features of the data and the generated graph associated with the deep representations of the nodes. Experimental results obtained on literature databases show that the proposed learning framework significantly improves clustering performance, compared with state-of-the-art approaches.

Abstract : Machine learning (ML) has penetrated all aspects of the modern life, and brought more convenience and satisfaction for variables of interest. However, building such solutions is a time consuming and challenging process that requires highly technical expertise. This certainly engages many more people, not necessarily experts, to perform analytics tasks. While the selection and the parametrization of ML models require tedious episodes of trial and error. Additionally, domain experts often lack the expertise to apply advanced analytics. Consequently, it necessitates frequent consultations with data scientists; nevertheless, such collaborations tend to cost the delays, which can lead to risks such as human-resource bottlenecks. As the complexity of these tasks increases, so does the demand for support solutions. In response, the field of automated ML (AutoML) is a data mining-based formalism that aims to reduce human effort and speedup the development cycle through automation. It can be applied to create pipelines of traditional ML models and ensembles, or to search for neural network architectures (NAS). In this regard, existing approaches include Bayesian optimization, evolutionary algorithms as well as reinforcement learning. These approaches have focused on providing user assistance by automating parts or the entire data analysis process, but without being concerned on its impact on the analysis. The goal has generally been focused on the performance factors, thus leaving aside other important and even crucial aspects such as computational complexity, confidence and transparency. In the talk we will present an overview of the main components of AutoML, the search spaces representing ML models, the search strategies, and the Explainability of automated AI.

Abstract : (kernel) Fisher Discriminant Analysis
Fisher Discriminant Analysis (FDA) and its kernel version, Kernel
FDA, are common supervised learning methods for dimensionality
reduction and class separation. The objective of this tutorial is
to introduce you and expand your knowledge of this technique.
First, I will recall the notions of projection and reconstruction.
Then, I will present the main ingredients of FDA : the betweenclass, the within-class and total scatter matrices. Next, I will
introduce the FDA’s principle and the corresponding optimization
problem to solve it. The dimensionality of the projective subspace
will also be discussed. I will also discuss on the main drawback
of FDA, i.e the possible singularity of the scatter and how to
prevent from it.
FDA is based on the assumption that data are linearly separable.
In a second part, I will present how the « kernel trick » allowed
to generalize LDA to nonlinear data sets. We will see how the FDA
criterion is formulated and solved in this case. Some
computational aspects and memory constraints will be also covered.
Finally, I will end the talk by some simulations on different
datasets.

Abstract: The utilization of Cyber-Physical Systems (CPS) and Artificial Intelligence (AI) in building energy management increase the energy efficiency and sustainability in our working or living spaces. These technologies have brought advancements in how we monitor, control, and optimize the energy consumption. Cyber-Physical Systems are the core of this transformation, integrating computational, communication, and control components into physical systems, creating interconnected environments. In the context of buildings, CPS allows real-time data collection from sensors distributed throughout the structure and the control of the demand. The data provided by the sensors includes temperature, light, air quality, occupancy, energy consumption and production of the distributed energy sources as PV or small WT. Artificial Intelligence plays an important role in analyzing the available data to optimize energy management. Machine learning algorithms are employed to forecast energy demand, identify potential wastage, and suggest real-time adjustments to save energy. Some of the benefits of the integration of Cyber-Physical Systems and Artificial Intelligence in building energy management are the improvement of the occupants’ comfort, the reduction of the energy costs and carbon footprint, the promotion of the sustainability.

Abstract: Optimization in computing science
Optimize and optimization are derived from Latin Optimus, which means 'best'. The
term to optimize was used in the mid-19th century with the meaning of making the best
or the most of something. In the 21st century, it has been extensively utilized in
technical fields, such as economics, calculus, mathematics, engineering, neuronal
networks, and so forth.
Optimization is a fundamental concept in the field of computing science. Its primary
objective is to make the system's efficiency while using limited resources. It can occur
at several levels : In optimization problems, scheduling and transportation are two
application cases that are often encountered; Optimization algorithms aim to find the
best solution that minimizes or maximizes a particular objective function; The
application program developers is to design their programs in such a way that they
make the most use of limited and expensive resources; Also using programming
languages, which are algebraic modeling languages makes coding easier and shorter.
Many tasks learning can be formulated as optimization problems, and these can be
improved by modern algorithms. Gradient descent and stochastic gradient descent are
by far the most popular differential optimization strategy used in machine
learning and deep learning. It is used when training data models, can be combined
with every algorithm and is easy to understand and implement.
On the other hand, gradient-free optimization methods are increasingly successful in
many fields of engineering or medicine where the functions to be optimized are black
box type, very expensive to evaluate, and defined on discrete/continuous mixed
spaces.
The purpose of this tutorial is to provide a brief overview of the gradient descent
algorithm, its current usage, and its advantages and disadvantages. In addition, it
presents the most prominent gradient-free optimization methods that have been
developed in recent years, particularly in genetic algorithms.

The computational costs of injection molding simulations have been increasing in the past years due to the higher complexity of the embedded models. This is especially problematic in case of using such simulation models for optimization routines or sensitivity analyses. One way to overcome this challenge is by having a surrogate model, also known as a metamodel, of these high-fidelity simulations, which provides a cheaper way to perform these types of analyses. These surrogate models can play an important role in the case of the injection molding of semi-crystalline polymers to model the flow-induced crystallization process. To date, most commercial software do not explicitly take polymer crystallization into account leading to various errors in the fill predictions as well as the calculation of warpage and shrinkage. This is mainly due to the common complexity of the models used to describe crystallization and the challenging respective model parameter identification process under injection molding conditions. To close this gap, in this thesis, the feasibility of using surrogate modeling to identify modeling parameters is first studied. This is then followed by the implementation of a thermo-mechanical crystallization model in order to describe the flow-induced and quiescent crystallization of a semi-crystalline thermoplastic material a during injection molding. The crystallization model is defined alongside crystallization-dependent viscosity, PVT and solidification models in the commercial software Autodesk Moldflow Insight 2021 using the Solver API feature. The model parameters are identified using a calibration scheme that employs three surrogate models representing the simulated pressure results to perform a multi-objective optimization. The fill predictions as well as the calculated pressure fields are presented using the calibrated model parameters in comparison to those measured during the actual injection molding of a polyoxymethylene part with different process conditions. The results show major improvements in the predictions of the pressure signals as well as the filling status of the produced parts and the estimated skin layer thicknesses formed under high-shear conditions. Additionally, the calibrated models are tested using various mold geometries to assess the calibrated models' performance.
