Panel Session 2: “Research in industry vs. academia”Problem Focus & Recognition Industry tends to focus on concrete problems. In academia, broader issues are often addressed. Authorship and credi
From the Fourier Series to the Fourier Transform to the Discrete Fourier Transform: Demystifying the Formulas
In realms as broad as electrical engineering, acoustics, optics, signal processing, quantum mechanics, and econometrics, the Fourier Series, Fourier Transform, and Discrete Fourier Transform play a pi
On Convolutional Neural Networks and Photographic Lenses
Convolutional neural networks are camera lenses to a computer. The analogy does not stop at the point that both compress visual information: The evolution of convolutional neural network architectu
Our Motivation for Maintaining Our Blog
今之博客，乃昔（初高中）之错题本之翻版也。昔之背景知识、解题思路、高效算法，今之认识、洞见，皆为辛苦求索所得，故笔录之，以期日积月累，唯“应试”“科研”之直接目的异也。 This blog is a replica of our previous “problem books” used for junior and senior high school. In the past, we woul
