Yupoo Picture Manager serves tens of millions of users and manages tens of billions of pictures. As its user gallery is growing larger, Yupoo has an urgent business need for a solution that can quickly locate the image. In other words, when a user inputs an image, the system should find its original…

With the continuous development of network technology and the ever-expanding scale of e-commerce, the number and variety of goods grow rapidly and users need to spend a lot of time to find the goods they want to buy. This is information overload. To solve this problem, the recommendation system came into being.
The recommendation system is a…Continue

Summary: Autonomous vehicles (AUVs) and many other systems that need to accurately perceive the world around them will be much better off when image classification moves from 2D to 3D. Here we examine the two leading approaches to 3D classification, Point Clouds and Voxel Grids.

Summary: This may be the golden age of deep learning but a lot can be learned by looking at where deep neural nets aren’t working yet. This can be a guide to calming the hype. It can also be a roadmap to future opportunities once these barriers are behind us.

What is an artificial intelligence (AI)?
Most of us can not imagine a single day without a computer. With the rapid development of technology, various devices that simplify people's lives become more accessible. This is also connected with modern computers, which are capable of providing impressive fast processing of information.
Modern business uses the full potential of information technology. This allows you to store important data and manage it…Continue

...That is the question.
Further study often seems the most appealing route to go down, and for many companies out there it’s often heralded as a must have for data science, but it isn’t always so and isn’t always pivotal in advancing your career.
A Ph.D. is your own original, unique research…Continue
In recent years, the field of object detection has seen tremendous progress, aided by the advent of deep learning. Object detection is the task of identifying objects in an image and drawing bounding boxes around them, i.e. localizing them. It’s a very important problem in computer vision due its numerous applications from self-driving cars to security and tracking.
Prior approaches of object detection…Continue

I spotted an interesting book in my local library recently: The Final Report of the Truth and Reconciliation Commission of Canada . I thought to myself, our government spent considerable resources on this commission. I should at least browse through the final report. I flipped through the first few pages. I found a note saying that the contents are public domain. In this blog, I reproduce some of the contents of the report to create a setting for my discussion on operational data. …Continue

Last year I started developing a Face Recognition model. I started with static pictures and using Wolfram Mathematica. This year I found out we can do the same job using OpenCV in Python, or creating specific filters in R and applying Weierstrass and Gaussian transformation.
There are lots of difficulties in recognizing faces of the same person, like: position, rotation of face, age, feeling, brightness, gamma, contrast, gamma, saturation, obstacles like hands,hair and so…Continue

When I read a blog, I often find myself in deep thought as I approach the end, trying to determine if the author has said anything that I might be able to use. A blog doesn't have to say anything. Nor does it have to be useful to me specifically. It might simply offer a personal reflection on life. As a person who also writes blogs, I…Continue

Thermometers and scales to measure weight appeared in retail outlets long ago. Blood pressure monitors perhaps came later. Pedometers and heart-rate monitors seem more recent - possibly closer to my time. I saw several devices while doing this blog intended to electronically record among other things hours of sleep; these are designed to be worn on the body all the time. A couple of weeks ago, I bought something to give the heart rate and blood oxygen saturation level. I consider it a real…Continue

I was often the lone wolf among my peers in university because I supported a prominent place in society for corporations and an important social role for capital. I questioned whether the directors and executives of companies entered into boardrooms really intending to “oppress” people such as minorities and people with disabilities. Did they deliberately make bathrooms inaccessible to people in wheelchairs perhaps to advance their preconceptions of who gets to go to the bathroom, I pondered…Continue
