"In machine learning, the goal is not just to fit the data, but to find a model that captures the underlying structure of the data."
不要为成功而努力,要为做一个有价值的人而努力。
所以,即使做很困难的事情,也一定能够达到目的,没听说过想达到自己的愿望,而能回避困难的。 
"We are all searching for something, but sometimes what we are searching for is already within us."
