Title: Credibility of Machine Learning Through Information Granularity

Abstract: Over the recent years, we have been witnessing numerous and far-reaching developments and applications of Machine Learning (ML). Efficient and systematic design of their architectures is important. Equally important are comprehensive evaluation mechanisms aimed at the assessment of the quality of the obtained results. The credibility of ML models is also of concern to any application, especially the one exhibiting a high level of criticality commonly encountered in autonomous systems and critical processes of decision-making. With this regard, there are a number of burning questions: how to quantify the quality of a result produced by the ML model? What is its credibility? How to equip the models with some self-awareness mechanism so careful guidance for additional supportive experimental evidence could be triggered?

Proceeding with a conceptual and algorithmic pursuits, we advocate that these problems could be formalized in the settings of Granular Computing (GrC). We show that any numeric result be augmented by the associated information granules being viewed as an essential vehicle to quantify credibility. A number of key formalisms explored in GrC are explored, namely those involving probabilistic, interval, and fuzzy information granules. Depending on the formal settings, confidence levels and confidence intervals or coverage and specificity criteria are discussed in depth and we show their role as descriptors of credibility measures.

The general proposals of granular embedding and granular Gaussian Process models are discussed along with their ensemble architectures. In the sequel, several representative and direct applications arising in the realm of transfer learning, knowledge distillation, and federated learning are discussed.

Title: A new paradigm to leverage formalized knowledge and machine learning

Abstract: To develop a unified framework which accommodates and enables machine learning and logical knowledge reasoning to work together effectively is a well-known holy grail problem in artificial intelligence. It is often claimed that advanced intelligent technologies can emerge when machine learning and logical knowledge reasoning can be seamlessly integrated as human beings generally perform problem-solving based on the leverage of perception and reasoning, where perception corresponds to a data-driven process that can be realized by machine learning whereas reasoning corresponds to a knowledge-driven process that can be realized by formalized reasoning. This talk ill present a recent study in this line.

Title: Recent Advances in Assessing Time Series Similarity Through Dynamic Time Warping

Abstract: Time series are a ubiquitous data type that capture information as it evolves over time. Dynamic Time Warping is the classic technique for quantifying similarity between time series. This talk outlines our impactful program of research that has transformed the state of the art in practical application of Dynamic Time Warping to big data tasks. These include fast and effective lower bounds, fast dynamic programming methods for calculating Dynamic Time Warping, and intuitive and effective variants of Dynamic Time Warping that moderate its sometimes-excessive flexibility.

Title: ChatGLM: Run your own “ChatGPT” on a laptop

Abstract: Large language models have substantially advanced the state of the art in various AI tasks, such as natural language understanding and text generation, and image processing, multimodal modeling. In this talk, I am going to talk about how we build GLM-130B, a bilingual (English and Chinese) pre-trained language model with 130 billion parameters. It is an attempt to open-source a 100B-scale model at least as good as GPT-3 and unveil how models of such a scale can be successfully pre-trained. Based on GLM-130B, we have developed ChatGLM, an alternative to ChatGPT. A small version, ChatGLM-6B, is opened with weights and codes. It can be deployed with one RTX 2080 Ti (11G) GPU, which makes it possible for everyone to deploy a ChatGPT! It has attracted over 2,000,000 downloads on Hugging Face in one month, and won the trending #1 model for two weeks.

Title: Topological Data Analysis : Discriminative Representations for Persistence Diagram

Abstract: Topological data analysis (TDA) extracts topological features to quantify the shape of data. TDA has found applications in many fields, including computer vision. In TDA, persistence diagrams (PDs) are topological descriptors of data. However, PDs are not vector so they cannot be directly used in machine learning methods.

Recent efforts have transformed PDs into vectors to enable machine learning tasks (classification, regression, dimension reduction, etc). However, existing methods highly depend on pre-defined polynomials to map PDs to vector representations. This presentation introduces two recent advances in PD representation: polynomial representations and Hilbert space embeddings. These representations could extract more discriminative topological features without requiring pre-defined polynomials.

The representations enable applying various machine learning tasks to PDs and extracting insights from different types of topological datasets. Our work seeks to open new research directions and applications of TDA in chemical/biological science, and materials engineering.
