1) What is Keras?
Keras is an advanced neural network API written in Python, which can run with TensorFlow, CNTK, or Theano as the back end. The development of keras focuses on supporting fast experiments, and the ability to convert your ideas into experimental results with minimal delay is the key to good research. In particula ...

least square method
What is the essence of least squares Taking measuring the length with different rulers as an example, several measured values are obtained. How to determine the true value? "y, which minimizes the sum of squares of errors, is the true value." this is based on the fact that if the error is random, the measured ...
