Title: Formal Concept Analysis, A framework for Knowledge Structuring and Exploration.
--Applications to Component/Service Directories and Product Lines.

Abstract: Formal Concept Analysis (FCA) can be summarized by the equation: objects + attributes = concept hierarchy. In other words, whenever you dispose of a set of objects or entities described by a set of attributes, properties, predicates, characteristics, graphs, whatever the employed vocabulary and the nature of things, FCA can help you to: (1) group a maximal set of objects sharing a maximal set of attributes into a concept, and (2) hierarchically organizing the set of concepts. Its generic perspective and its strong foundation on lattice theory make FCA a Swiss knife in knowledge engineering, information retrieval and machine learning, where it can be used to build classes and conceptual classifications, to mine implication and association rules, to build ontologies or recommendation systems, or for exploratory search. FCA is used for applications in a wide range of domains such as software engineering, environment and life sciences, and social sciences. In this talk, we will introduce FCA and Relational Concept Analysis (RCA), which is one of FCA recent extensions to approach multi-relational datasets. RCA helps classifying objects from several categories both through their intrinsic attributes and through their relations to objects of other categories, propagating the concept formation from one category to another. We will overview several applications of FCA and RCA in software engineering, and we will focus on software component and service directory building, and in the domain of extractive adoption of product lines.

Zhiquan (George) Zhou

University of Wollongong, Australia
Topic: Automated testing of real-life self-driving systems and beyond
Abstract: Advances in machine learning have led to a surge in artificial intelligence (AI) applications with substantial investment from industry and governments. The past year has seen the development of innovative customer service solutions powered by a combination of natural language processing and machine learning technologies, as well as an increasing expectation for systems that exhibit high-level intelligence, including medical diagnosis tools and autonomous vehicles. Most of these systems, however, are not easy to test by automated means.
Software testing is essential for the quality assurance of AI systems. To achieve a high standard of testing, the tester needs to generate, execute, and verify a large number of tests. These tasks can hardly be done without test automation, for which the “oracle problem” is a main challenge. In software testing, a “test oracle” is a mechanism against which testers can decide whether the outcomes of test case executions are correct. It is, however, often difficult to design an oracle (automated, if possible) to check the correctness of an AI system’s output. For example, an AI-powered search engine (such as Google) is not easy to test due to the sheer volume of data being processed. Likewise, constructing a fully automated oracle for the testing of autonomous vehicles is especially challenging (except for checking some simple events such as collisions), as it essentially involves recreating the logic of a human driver’s decision making.
In this keynote, I first introduce recent advances in addressing the oracle problem, highlighting metamorphic testing as a practical and cost-effective approach for automated testing of AI systems. I show how we detected fatal software faults in the LiDAR obstacle-perception module of the real-life self-driving car system Baidu Apollo—we reported the alarming results eight days before Uber’s deadly crash in Tempe, Arizona, in March 2018. (Some of the results have been published in CACM, March 2019). I next discuss practical methods of identifying useful metamorphic relations, a core step of metamorphic testing, and introduce the concept of “metamorphic relation patterns.” I then go on to show the usefulness of the “pattern” concept in testing different types of AI applications, including machine translation, Google Maps navigation, web search, image and video analysis, eCommerce websites such as Amazon, and so on. I conclude this keynote speech by playing a short video to show some of the recently detected issues in the planning and vehicle-control modules of the Apollo system.
