Speech Title: "Recurrence Analysis in Deep Learning of Medical Images and Physiological Signals"

 

Abstract: Time-frequency and time-space properties of medical images and physiological time series are introduced as a robust tool for deep learning-based classification. Experimental results obtained from the classification of benign and malignant mediastinal lymph nodes in lung cancer on computed tomography and sensor-induced physiological signals of Parkinson's disease and heart irregularity show the effectiveness of the use of recurrence analysis in deep learning. The proposed approach has the potential for 1) achieving very high classification accuracy, 2) saving tremendous time for data learning, and 3) being cost-effective and user-comfortable for clinical trials by reducing multiple wearable sensors for data recording.

Speech Title: "Deep Learning-Based Pathway Analysis using Hierarchical Structural Component Models"

 

Abstract: Many statistical methods for pathway analysis have been used to identify key genes and proteins within previously known pathways associated with a given disease, or to detect novel pathways from proteins known to be disease-related. It is well known that pathways overlap and are highly correlated. However, most pathway methods do not consider this correlation between pathways, which may cause false negative or positive errors. Recently, a hierarchical structural component model (HisCoM) was proposed to take this correlation into account by fitting all pathways in one model simultaneously. However, since HisCoM assumes linear contributions of biological factors to the effect of a pathway, it does not fully project the complexity of relationships between biological factors. We propose DeepHisCoM which uses deep learning to find complex contributions of biological factors to the effect of a pathway. DeepHisCoM has all advantages of HisCoM such as using the hierarchical structured information in pathways. Through simulation studies, DeepHisCoM was shown to have higher power in the non-linear pathway effect and comparable power for the linear pathway effect, when compared to the conventional pathway methods. Application to a Hepatocellular Carcinoma (HCC) dataset demonstrated that DeepHisCoM successfully identified well known pathways that are highly associated with HCC such as Tryptophan metabolism and Primary bile acid biosynthesis.

Speech Title: "From Known Knowns to Unknown Unknowns in AI: Historical and Technical Issues"

 

Abstract: AI has been originally developed for closed-world, and noise-free, problems where the possible states of natures and actions that a rationale agent could implement were perfectly known. One could argue that, at that time, AI dealt with known knowns. Since the 1980s, when machine learning became an experimental science, AI researchers started to tackle pattern recognition problems with noisy data, using probability theory to model uncertainty and decision theory to minimize the risk of wrong actions. This was the era of known unknowns, characterized by the rise of benchmark data sets, larger and larger year after year, and the belief that real world problems can be solved collecting enough training data. However, recent results have shown that available data sets have often a limited utility when used to train pattern recognition algorithms that will be deployed in the real world. The reason is that modern machine learning has often to face with unknown unknowns. When learning systems are deployed in adversarial environments in the open world, they can misclassify (with high-confidence) never-before-seen inputs that are largely different from known training data. Unknown unknowns are the real threat in many security problems (e.g., zero-day attacks in computer security). In this talk, I give a historical and technical overview of the evolution of AI and machine learning for pattern recognition, and discuss how this evolution can be regarded as a transition from known knowns to unknown unknowns, and the key role that adversarial machine learning plays to make AI safer.
