# Reverse GAN, changing the distribution of the data to normal noise
I have a dataset which contains the data from 10 classes. The classes look well-separated that the accuracy rate of different classifiers is more than 95%.
The goal is to change the data distribution in a way that they can’t be not easily classified... | {} |

#### 5 polymerization setting
Dear all
Hello, I'm trying to run GRRM 17 program to examine polymerization reactions including Butadiene.
At first, I have tried to calculate the very simple reaction as below. However, any TS structure has NEVER been generated although GAMMA parameter was very larg... | {} |
Consecutive Integers
Number Theory Level pending
Two sets $$\{a_n\}$$ and $$\{b_n\}$$ of 4 consecutive positive integers have exactly one integer in common. Let
• $$A$$ denote the sum of the integers in $$\{a_n\}$$, which is the set with the greater numbers, and
• $$B$$ denote the sum of the integers in $$\{b_n\}$$.... | {} |
# The State of LDC on Windows
LDC is one of the three major D compilers. It uses the same frontend as DMD, the reference implementation of the language, but leverages LLVM for optimization and code generation. While it has been stable on Linux and OS X for quite some time, support for the Windows operating system fami... | {} |
GKC
Background: When I was the editor of Gilbert Magazine, I was responsible for the “Tremendous Trifles” column. It was occasionally hard to find a sufficient amount of interesting GKC material to fill the page, so John Peterson sent me a file full of Chesterton ancedotes. They were idiosyncratic, historical, and Che... | {} |

Description:
CRB has a tree, whose vertices are labeled by 1, 2, …, N. They are connected by N – 1 edges. Each edge has a weight.
For any two vertices u and v(possibly equal), f(u,v) is xor(exclus... | {} |
1. ## Integration
How do you evaluate integral(x^1/2)sinx dx ?
2. You can use the Taylor expansion of $\displaystyle \sin x$ around $\displaystyle x=0$, then multiply each term of the series by $\displaystyle x^{\frac{1}{2}}$ and finally integrate term by term...
Kind regards
