The
President's Lecture Series: Excellence in Academia offers a platform for CityU
academics to discuss wide-ranging academic investigations with students,
faculty and staff across the CityU community.
Big data and machine learning are currently two main techniques used in
artificial intelligence (AI) applications.
A historical review of AI and explain the basic principles of data
classification and machine learning methods would be discussed in this lecture. Before the lecture, I took a photo with guest
speaker Prof. Hong Yan for memory.
I also met CityU
President Prof. Way Kuo and my old colleague Mr. Spencer Chan (Sr. Manager,
Business Development, HKSTP).
Professor Hong
Yan (Chair Professor of Computer Engineering, CityU) was our guest speaker and
his topic named “Big Data Analysis and Artificial Intelligence: Opportunities
and Challenges”.
In the
beginning, he introduced where data come from such as multimedia, business
observation, R&D, etc. Camera especially digital camera was sensor for data
acquisition. (Remark: The mirror image
showed the full house of participants.)
Then Prof. Yan
then introduced the history of AI from 1950s to present. After 2011, big data and deep learning became
the hot topics in AI.
Prof. Yan mentioned
the 4th industrial revolution in which 100 startups using AI to
transform industries. He stated expert system advantage on using intuitive
rules but noise sensitive.
And then Prof. Yan briefed machine learning algorithms as following diagram. Image Pre-processing and feature extraction were also discussed. The extraction included key points, contours, shape descriptors, main frequency components, etc.
Dimensionality
reduction through data transformation, Bayes Classifier, and Deep Learning
Neural Network were explained.
After that he
demonstrated Lip Sync and Human Face Animation to us. (http://www.hy8.com/main.php
)
Tensor models
for hypergraph matching was discussed.
For one dimension of data set, it is Vector. For two dimension of data set, it calls
Matrix. Tensor is for three or more
dimension of data set. And then he also
introduced cell image tracking and lineage analysis, Chromatin Structure, Biomolecular
Surface Curvature, Hydrogen Bonding in Biomolecules, Probabilistic Relaxation
Labeling (PRL) … etc.
Most
interested thing was Protein 3D Structures. Prof. Yan said it could be simulated by
computer rather than using X-ray diffraction or NMR to find out the
structure. So many people may loss job in
future.
Finally, Prof. Yan compared AI and Human Intelligence in terms of templating matching, numerical computation, deal with large datasets & poor input quality, flexibility, common sense and creativity.
Key theories
and methodology in different areas such as computer, big data and AI were
discussed.
Lastly, he
showed a big picture from 1915 to 1965 and predicted from 2015 to 2065. He said many key concepts were presented 50 years
ago.
At the end,
Prof. Yan summarized that Big Data and AI had many applications and tremendous
commercial potentials. Currently, we
needed large training datasets and worked in restricted environment. In order to achieve major breakthroughs, we
needed to focus basic principles, mathematical foundation, taking risks and
having a new and big ideas.
