Speech Title: Credibility and Interpretability/Explainability in Critical Applications of Machine Learning: An Environment of Granular Computing
Abstract: Over the recent years, we have been witnessing numerous and far-reaching developments and applications of Machine Learning (ML). With the plethora of applications found in critical areas such as autonomous vehicles, health care, networks, complex decision-making environments.
Two interrelated challenges become more apparent, namely credibility and interpretability/explainability. Both of them directly impact the acceptance and usefulness of ML constructs in a real-world environment. The credibility is also of concern to any application, especially the one being associated with a high level of criticality.
The notions of interpretability and explainability are formulated and we show how they are realized through a number of auxiliary models built upon the black models of ML constructs. Model-agnostic explainable models are discussed.
Proceeding with a conceptual and algorithmic pursuits, we advocate that the above problems could be formalized in the settings of Granular Computing. We show that to credibility any numeric result be augmented by the associated information granules and the quality of the results is quantified in terms of the characteristics of information granules. Different directions are discussed and revisited including confidence/ prediction intervals, granular embedding of ML models, and granular Gaussian Process models.
When coping with interepretability nd explainability of ML, information granules and their processing offer key advantages in a number of ways: (i) by stressing the product instead of product perspective and emphasizing importance of interactivity between the user and the explanation module, (ii) by incorporating suitable levels of abstraction, (iii)by building explanation layers with rule-based computing, (iv) by defining and quantifying stability of interpretation, and (v) by proposing ideas of granular counterfactual explanation.

Speech Title: Machine Learning Perspectives
Abstract: Training in Machine Learning is a crucial aspect that affects the credibility of the system in terms of performance and is employed for robust applications such as in healthcare systems. Machines or algorithms, in wide challengeable applications in security or vision or health care early predictions, learn from data. Nevertheless, in most cases, the extensive and unbalanced data and noise make it unreliable in prediction accuracy. Supervised machine learning is and was one of the aspects of providing artificial intelligence-based solutions. However, this is and was limited due to the difficulty of labeling big data and many crucial problems in weak relations and noise in data. Semi-supervised learning, for example, Multiview learning, could assist in solving these problems. In many published research, there are still problems in providing machine learning models that are unbiased and efficient in terms of robustness and resilience in data-driven systems. Multiclass classification still has problems in terms of clear definition in class classification, bias, imbalance and weak relations, making machine learning for multiclass classification insecure for classification or regression analytics. This causes limitations in applying such technology in medical applications and diagnosis prediction. In this lecture, I will outline these problems in our one-class classification project. These are related to providing more robust accuracy prediction with some uncertainty that can help us have more accurate classification and prediction. We have applied such findings in health care for heart sickness and seizure early prediction like in https://doi.org/10.1016/j.cmpb.2022.107277 and https://doi.org/10.1016/j.inffus.2023.102023
We also have deep learning models, which also have challenges related to evidential deep learning and fairness relative to data. There are important issues in expanding research in evidential deep learning, in which uncertainty prediction of variational Auto encoders can provide decisions on evidential distribution, which in turn helps to provide a measure of uncertainty in decision.
We currently have a research project titled “Healthcare Risk Prediction on Data Streams Employing Cross Ensemble Deep Learning”, which is supported by Japan Science Promotion Society (JSPS). In this project, we have employed one-class classification deep neural network for health care prediction. In this lecture I will outline of these perspective and discuss challenging trends.

Speech Title: Advanced Machine Learning Structures over Big Data Repositories: Definitions, Models, Properties, Algorithms
Abstract: Big data repositories contain great-value data from which actionable knowledge insights can be meaningfully derived in order to support a wide spectrum of modern applications, such as smart cities, social networks, e-science, bio-informatics, and so forth. How to extract these interesting patterns from such large-scale repositories? The latter is a fundamental research question that is still open. Inspired by the described research challenge, this talk will explore the issue of supporting advanced machine learning structures over big data repositories, whose final goal is realizing meaningful knowledge discovery tasks. These “structures” are rather programs than tasks so that they incorporate machine learning procedures within high-level (program) controls whose main goal is that of magnifying the expressive power of the whole big data analytics process implemented as a collection of singleton big data analytics tasks. In turn, each task is implemented in term of a proper advanced machine learning structure. The talk will provide introduction and motivations to the investigated problem, analysis of related work, and the proposal of a formal framework supporting these innovative structures.
