Three NYU Graduate Courses Available in OpenStudy

E-mail Print PDF

I am very glad to introduce you with the three NYU graduate courses available now in my OpenStudy project:

Computational Photography

Computational Photography: Computational photography draws my interests not only because people in this area develope algorithms that produce many amusing results, but also because it is a greatly applicable science that requires a good possession of mathematics in a broader sense. It intersects closely to other computer science and eletronic engineering disciplines such as machine learning and digital signal processing.

Machine Learning and Pattern Recognition: The course covers a wide variety of topics in machine learning, pattern recognition, statistical modeling, and neural computation. It covers the mathematical methods and theoretical aspects, but will primarily focus on algorithmic and practical issues. Machine Learning and Pattern Recognition methods are at the core of many recent advances in "intelligent computing". Current applications include machine perception (vision, audition, speech recognition), control (process control, robotics), data mining, time-series prediction (e.g. in finance), natural language processing, text mining and text classification, bio-informatics, neural modeling, computational models of biological processes, and many other areas.

Operating Systems: The topics covered include a review of linkers and loaders and the high-level design of key operating systems concepts such as process scheduling and synchronization; deadlocks and their prevention; memory management, including (demand) paging and segmentation; and I/O and file systems, with examples from Unix/Linux and Windows. Programming assignments may require C, C++, Java, or C#.

As always, I am very glad to share with you my experience of studying computer science. If you have any suggestions to the OpenStudy project, don't hesitate to contact me!

Astronomical Computing: Fast n-PCF Approximation using RCSF

E-mail Print PDF

Eye-stars

It is a piece of great news that our research on solving an astronomical computing problem, named n-Point Correlation Function, has been accepted by IEEE CloudCom HPC Workshop.

This research is about two parallelizable algorithms that approximate the n-PCF problem, which is used by astronomers for CMB, wealk lensing, black hole detection, galaxy clustering, and queries of the origin of the universe.

Since we cannot present ourselves on the workshop, a video was made to present our ideas. The details about this project, including the video presentation, can be found here.

 

New OpenStudy Notes: Linear Dynamic Systems from Stanfrod

EE263

I have finished the online notes of another course from Stanford, whose title is 'Linear Dynamic Systems'. This course and 'Signals and Systems' share some common topics such as transforms and state transfer. But LDS is much more general. Below is the introduction of this course from Stanford SEE:

Introduction to applied linear algebra and linear dynamical systems, with applications to circuits, signal processing, communications, and control systems.

Topics include: Least-squares aproximations of over-determined equations and least-norm solutions of underdetermined equations. Symmetric matrices, matrix norm and singular value decomposition. Eigenvalues, left and right eigenvectors, and dynamical interpretation. Matrix exponential, stability, and asymptotic behavior. Multi-input multi-output systems, impulse and step matrices; convolution and transfer matrix descriptions. Control, reachability, state transfer, and least-norm inputs. Observability and least-squares state estimation.

Full notes can be accessed by clicking here or in our OpenStudy project.

 

ICIG Paper Presentation on Aug.13th

ICIG2011

It is glad for me that our submitted paper 'Texture Transfer in Frequency Domain' has been selected as an oral presentation paper for Image Processing sessions in ICIG (the 6th international conference on image and graphics). In Hefei I will also personally join the Huang Shan trip and Huangmei Opera performance.

Thanks for my advisor, Mr Liu Shiguang's sincerely advisement for my undergraduate research. I will keep on the career of my research, and following the motto of my alma mater Tianjin University.

Project Manager Now Supports Chinese

E-mail Print PDF

After days of working I have fully translated the projectfork's interface into Chinese. Previously there was a problem that projectfork cannot store Chinese characters correctly, and the problem has been identified: The MySQL tables of Projectfork are in latin-1 coding. I have converted all the tables into utf8 and now it supports Chinese.

The translate language package has now been published in projectfork's offcial forum, version 0101. If you find anything in the translation that is not accurate or correct, feel free to contact me.
