Title: "Hybrid Classification Approach for Correlated Multimodality Images: Unmixing Processing + Artificial Intelligence"

Abstract 

Correlated multimodal images allow to capture spatial-temporal or spatial-spectral information simultaneously from a scene. These types of images had found applications in diverse fields, as earth observation to identify types of vegetation, medical diagnosis to detect cancerous lesions in the skin or oral cavity, food inspection to distinguish contaminants, non-destructive testing to perceive defects in materials, among others. One of the main challenges in this field is to make an efficient and fast processing of the vast acquired information. In this talk, I will focus on the classification problem of correlated multimodal images by a hybrid approach. Hence, first, linear and nonlinear unmixing are used to extract features to guide the classification process by applying the algorithm “extended blind end-member and abundance extraction”, which was developed by our research team. Next, machine learning and deep learning are applied to achieve the final pixel labeling. In the talk, I will focus on the applications to medical diagnosis and non-destructive testing for our hybrid classification approach.

Title: Fault Diagnosis in Petri Nets 

Abstract

In this problem both, the model and set of potential system faults are known, and the actual occurrence of a fault must be determined from the system outputs during its evolution.

First, we review the basic concepts about fault diagnosis and Petri nets (PN). Afterwards, we present sufficient structural conditions to guarantee the non-concurrent diagnosability property in a PN structure. In this case, the non-existence of infinite length indistinguishable output cycles is enough to determine that faults are diagnosable; from the PN structure perspective, it is equivalent to the non-existence of T-semiflows that could be fired with independence of the fault occurrence. Later, the concurrent diagnosability is presented to deal with system exhibiting concurrence.

Subsequently, the diagnosability problem in Timed Continuous Petri net (TCPN) is also addressed from a structural perspective. Since TCPNs are positive affine switched linear systems, the diagnosability is more complex to analyze, and reported results are based on the analysis of the paths from potential faults to sensors. When the transfer functions from potential faults to the outputs are all different from each other, then every fault is diagnosable. Then, a brief review of the results about fault diagnosis in linear systems using unobservability spaces is presented, establishing

bridges between the diagnosis in linear systems and Petri nets. Finally, the distributed diagnosis problem, using the notion of quotient Petri net, is addressed. The advantage of this approach is that diagnosability can be achieved efficiently, because T-semiflows that could be fired with independence of fault occurrence are efficiently obtained.

Title: "An Impulse Response Formulation for Machine Learning of 3D Printing Accuracy"

Abstract: 

Machine learning for additive manufacturing (ML4AM) has emerged as a viable strategy in recent years to enhance 3D printing performance. However, the amount of data required for model training and the lack of ability to infer process insights can be serious barriers to industrial applications.  Due to the nature of low-volume fabrication of infinite product variety in 3D printing, ML4AM also faces ``small data, big tasks" challenges to learn heterogeneous point cloud data and control the quality of new designs.  This talk presents the critical connection of the impulse response formulation in control theory with small-sample machine learning of 3D printing accuracy. This fabrication-aware formulation builds the foundation for applying well-established control theory to the intelligent quality control of 3D printing. It not only provides theoretical underpinning and justification of our previous work on ML4AM, but also enable new control opportunities.
