Summary

(Currently I am very busy so I am only taking mentees seeking for long term mentorship, please DO NOT reach out to me if you are looking for only one or two session)
I can help you practice live coding interview, understanding algorothm / data structure / machine learning / deep learning in python. I am a Machine Learning Engineer in Thales with hands on machine learning experience. Currently living in SIngapore (UTC+8 timezone) Rich experience interviewing with big company and interview candidates. one of my live coding session as a interviewee is featured at interview.io as a showcase interview! https://start.interviewing.io/showcase. I was in the competitve programming team in college. I was the student with the highest grade in algorithm class. I have lots of interview experience, including Google, Roblox, Postmate, Thales and more. You can have a mock interview session with me to get a taste of a real interview and get constructive feedback. The best way to work with me is to have a long term mentorship to enhance you problem solving skills. I will cover differenct popular interview topic each week and we will work on the questions together. I will point out your blind spot, guide you to refactor your code and reach optimal solution. Working with me is more fun than working by yourself :)

Reproduced Gatys, Leon A., Alexander S. Ecker, and Matthias Bethge. "A neural algorithm of artistic style". I redrew a photo of Wonder Woman with the style of Van Gogh. By identifying that correlations between the shallow layer feature maps is a representation of styles, I added the style loss to the objective function, fixed the weight and applied gradient descent on the initial image to minimize the objective function.
