Machine learning (--regularization:regularized) Linear regression
Gradient descent
Without regularization
With regularization
Θ0 is the same as the original, no regularization.
The θ1-n is slightly smaller than the original (1-αλ⁄m)
This article will cover:
(1) Another Linear Regression Method: normal equation; (2) Advantages and Disadvantages of gradient descent and normal equation;
Previously we used the Gradient Descent Method for linear regression, but gradient descent has the following features: (1) l
Supervised Learning
Learn a function H: X → y
H is called a hypothesis.
1. Linear Regression
In this example, X is a two-dimensional vector, x1 represents living area, and x2 represents bedrooms.
Functions/hypotheses H
Set X0 = 1.
Now, given a training set, how do we pick, or learn, the parameters θ? Now it is used to evaluate the θ parameter.

mainstream framework, of course, not to say that Keras and CNTK are not mainstream, the article does not have any interest related things, but the keras itself has a variety of frameworks as the back end, So there is no point in contrast to its back-end frame, Keras is undoubtedly the slowest. and CNTK because the author of Windows is not feeling so also not within the range of evaluation (CNTK is also a good framework, of course, also cross-platform, interested parties can go to trample on the

Model optimization is important for both traditional machine learning and deep learning, especially in deep learning, and it is likely that more difficult challenges will need to be addressed during training. At present, the popular and widely used optimization algorithm has

What is migration learning
In deep learning, the so-called migration learning is to adapt a model of problem A to a new problem B by simply adjusting it. In actual use, it is often completed problem a training model has more perfect data, and problem B's data volume is small. The adjustment process is based on the act
