AUGUST 21-24, AFTERNOON (13:30 - 15:00)

Lecture: Mathematical foundations of machine learning

Lecturer: Lê Hồng Vân, Institute of Mathematics of Czech Academy of Sciences

Abstract: Machine learning is an interdisciplinary field in the intersection of mathematical statistics and computer sciences. Machine learning studies statistical models, develops methods and algorithms for deriving predictors or meaningful patterns from empirical data. Machine learning techniques are applied in search engine, natural language processing, image detection, robotics, self-driving cars and artificial intelligence. In our lecture series we address the following questions:

- What is the mathematical model of learning?

- How do we quantify the difficulty/complexity of a learning problem and success of a learning machine?

- What are current tasks of machine learning?

- Can machines learn to think?

Lecture 1 (August 21): Learning, machine learning and artificial intelligence.

Lecture 2 (August 22): Statistical models and framework for machine learning.

Lecture 3 (August 23): PAC (probably approximately correct) learning theory.

Lecture 4 (August 24): Deep learning, pattern theory and algebra of human thoughts.




Title: Streaming dynamic and distributed inference of latent geometric structures 

Speaker: Nguyễn Xuân Long, University of Michigan, Ann Arbor

Time and Place: 15:30-17:00, VIASM 


We develop new models and algorithms for learning the temporal dynamics of the topic polytopes and related geometric objects that arise in topic model based inference. Our model is nonparametric Bayesian and the corresponding inference algorithm is able to discover new topics as the time progresses. By exploiting the connection between the modeling of topic polytope evolution, Beta-Bernoulli process and the Hungarian matching algorithm, our method is shown to be several orders of magnitude faster than existing topic modeling approaches, as demonstrated by experiments working with several million documents in a dozen minutes.



Tutorial Lecture:Gaussian and Dirichlet processes for statistical learning and inference 

Lecturer: Nguyễn Xuân Long, University of Michigan, Ann Arbor

Time and Place: 9:00-11:00, VIASM 


Bayesian nonparametrics is an area in statistics which provides a fertile and powerful mathematical framework for the development of many computational and statistical modeling ideas. The spirit of Bayesian nonparametrics is to enable the kind of inferential procedures according to which both the statistical modeling and computational complexity may adapt to increasingly large and complex data patterns in a graceful and effective way. This circle of ideas and techniques is expected to have increasingly large role to play in the era of big data. In this tutorial lecture, I will introduce Gaussian processes and Dirichlet processes, two of the most common tools that arise in Bayesian nonparametric model constructions for regression, classification, clustering, and density estimation problems. Computational issues and applications will be discussed.



Lecture: Ontology based Machine Learning 

Lecturer: Nguyễn Hùng Sơn, Warsaw University 

Time and Place: 9:00-11:00, VIASM 


One of the common problems in many machine learning or data mining projects is ralated to the issue called „information rich” but „knowledge poor”. Usually, the domain knowledge is presented either as an ontology or as a taxonomy (a lighter version of ontology) of concepts. In this talk we present some knowledge aquisition techniques as well as the utility of domain knowledge in some machine learning techniques. We will show that ontology can improve the accuracy of classification and clustering algorithms. Moreover, ontology can be also used to build a semantic evaluator for clustering algorithms.



Lecture: Neural Random Access Machines – a deep learning technique for sequential data. 

Lecturer: Nguyễn Hùng Sơn, Warsaw University 

Time and Place: 14:00-16:00, VIASM 

Abstract: We present a new neural network architecture inspired by Neural Turing Machines called a Neural Random Access Machine.  This architecture can manipulate and dereference pointers to an external variable-size random-access memory. It has been shown that the proposed model can learn to solve algorithmic tasks and is capable of discovering simple data structures like linked-lists and binary trees. For a subset of tasks, the learned solutions generalize to sequences ofarbitrary length. 



Public lecture: AI nào cho Việt Nam? 

Lecturer: Hồ Tú Bảo, VIASM 

Time and Place: 9:00-11:00, VIASM 


Trong phần đầu chúng tôi tóm tắt lại những nội dung cơ bản và tình hình phát triển của AI nói chung. Trong phần sau, dựa trên mục tiêu phát triển đất nước và tình hình phát triển AI ở Việt Nam, chúng tôi chia sẻ một số ý kiến về việc chúng ta cần và nên chú trọng vào những lĩnh vực nào của AI trong bối cảnh Việt Nam thời chuyển đổi số.



Lecture: Khoa học dữ liệu trong chăm sóc sức khoẻ và nghiên cứu y học 

Lecturer: Hồ Tú Bảo, VIASM 

Time and Place: 9:00-11:00, VIASM 


Chăm sóc sức khoẻ và nghiên cứu y học là lĩnh vực quan trọng của mọi quốc gia với rất nhiều thách thức. Trong những năm qua, lượng dữ liệu y tế đã tăng lên rất nhiều, mở ra khả năng khai thác và sử dụng chúng cho hai mục tiêu kể trên. Bài giảng này trước hết giới thiệu một bức tranh toàn cảnh về khoa học dữ liệu trong y tế, đặc biệt việc khai thác và sử dụng bệnh án điện tử. Phần sau của bài giảng giới thiệu một số công việc, bài toán  và kết quả nghiên cứu đề tài chúng tôi đã và đang tiến hành ở Việt Nam.
