This is a class about learning simulation's assignment.
Using a composite function as a probability density function.
In other words, to generate variable of composite function by uniform random number.

Introduction of Back Propagation(BP).
My understanding is far from perfect,
how to use, what's for, what can be? doubts are remained.
However i get more interest through this approach.
I'll make effort more about this.
Should Japanese Education Be Vocational Training School?T2C_
This is assignment of one class.
Wrote about Japanese education's issue.
This is first time to make a document for presentation
written in English.
I'm confused gradually because of depth of education problems.
There are infinity kind of ways.
Same as many problems, also this problem is not only which is better.
If I get more opinion, idea, view, I'm happy.
Parallel computation foundation's assignment 2. This is my first time using process partitioning. And compare process and thread partitioning by speed of circular constant computation.
