## Machine Learning Notes I

M

Lately, I was into the studying process of machine learning, and outputting(taking notes) is a vital step of it. Here, I am using Andrew Ng’s Stanford Machine Learning course in Coursera with the language of MATLAB. So the rest of the code I will write in this post by default are based on MATLAB. What is ML? “A computer program is said to learn from experience E with respect to some...

## AI Face Change Full Tutorial-Based On DeepFaceLab

A

Introduction AI face change is a product under Neuro Network and Machine Learning technologies. And this article aims to be a tutorial that could let people who do not have experience in Machine Learning to replace the face in one video with other faces. Key Words: #deepfakes #faceswap #face-swap #deep-learning #deeplearning #deep-neural-networks #deepface #deep-face-swap #fakeapp #fake-app...

## The TVC Rocket Idea

T

*2019/7/8 Before ALL: Hello folks, since the summer began, I have to say a project I have planed for a long time should get into its path now. And it is a serial, so I will update the lastest processes as I do. Basically, the goal is to build a fully fictional rocket which has a Thrust Vector Control(TVC) which allows the rocket could control the thrust direction stay toward the earth, and a...

## Why The Interval to Graph a Trig Equation in Polar Differ?

W

Boys, set your calculator to polar mode, and draw a graph of r=4sin(3θ), then set the first interval of [0,π] and the second one: [0, 2π] [0,π] [0,2π] They looks exactly the same, isn’t it? And if we take of the integral of these two to find the area, for the graph with interval [0,π], area = 4π, but for the graph with [0,2π] the area is 8π, thus, which one is the “true” one we...

## Check Out How The Surrounding Temperature Change The Color of Bismuth Crystal’s Oxidized Layer

C

It’s just a funny and chill little project, but I still believe no one did such research before 🙂

## Experiment Day#1 Crystallization and Oxidization of Bismuth

E

My team yesterday finished the first trail of the experiment.

Which is finding the relationship between temperature while bismuth being oxidize and color of the oxide layer

And the rule is: Low temperature is fully gold, as temperature goes high, it goes purple than blue.

## ʻOumuamua is Not a Spacecraft but a Comet

ʻ

Deemo Chen, grade 11 student. Barstow School – Ningbo Campus. Abstract 1I/2017 U1 (‘Oumuamua), a recently discovered asteroid in a hyperbolic orbit, is likely the first macroscopic object of extrasolar origin identified in the solar system. This paper mainly gives reasons why ‘Oumuamua should be a comet, by explaining three unusual behaviors of ‘Oumuamua which are unnormal ratio, strange track...

## Let We do Moon Stacking! And Processing

L

Since I moving my telescope to my school for my Astronomy Club, I put it for a long time because my club is still weak and no one in the club could be seem as a real club number. But I set up a small observation recently with another guy who are not in my club, and I took 16 photos of moon by my lovely A7RIII, however, the truth prove that it is useless to stack 16 photos, but I think it is a...

## How I understand the Ideal Gas Law

H

After learning the Gas law, that I got some general idea of the beauty of equations, I think the expression of textbooks is pretty strange, they trying to divide one simple formula to several different unclear ones, hmm… I think the better the equation is the more factors it includes in; it does not let the question become complicated but even make it even simpler because people do not need...
