. -Get more training samples -Try to use a set with fewer features -Try to obtain other features -Try to add multiple combinations of features -Try to reduce λ -Add Lambda Machine Learning (algorithm) diagnosis (Diagnostic) is a testing method that enables you to have a deep understanding of a Learning Algorithm and know what can be run and what cannot be run, it

If we are developing a machine learning system and want to try to improve the performance of a machine learning system, how do we decide which path we should choose Next?In order to explain this problem, to predict the price of learning examples. If we've got the

prediction example of the house price, suppose we have implemented a regular linear regression method to predict the price:However, when you find that this prediction is applied to a new training data with great error (Error), some solutions should be taken:Get more training Examplestry smaller sets of featurestry getting additional featurestry adding polynomial features (e.g. X1^2, x2^2, x1x2 ...) Try Decreasingλtry increasingλDiagnosis of machine

WEEK1:Machine learning: A computer program was said to learn from experience E with respect to some class of tasks T and performance measure P, if Its performance on tasks in T, as measured by P, improves with experience E. Supervised learning:we already know what we correct output should look like. Regression:try to map input variables to some continuous function.

Also promised to have some computer vision, I have also mentioned in the blog that there are some limitations.6.VeloxAs a server dedicated to the management of a large number of machine

ProfileThis article is the first of a small experiment in machine learning using the Python programming language. The main contents are as follows: Read data and clean data Explore the characteristics of the input data Analyze how data is presented for learning algorithms Choosing the right model and

Simple examples are used to understand what machine learning is, and examples are used to understand machine learning. 1. What is machine learning? What is machine

-validation error Here is also small, indicating that the model can also be very good to predict the unknown data)Finally, the polynomial regression model of the regularization parameter lambda = = 100 (λ==100) When the case:(there is underfit problem--less fitting-high deviation)The model "hypothetical function" curve is as follows:The learning curve graph is as follows:⑨ How to automatically select the ap

artificially set before the model begins the learning process, rather than by training the parameter data (such as B, W) in the normal sense.These parameters define the concept of a higher level of the model (model complexity, learning capability, etc.).You cannot learn directly from the data in the Standard Model training process, you need to define it in advan

input. How can we let machines get the kind? Using data and samples to establish operational knowledge is machine learning.Machine Learning:Machine Learning has a long history and many textbooks have explained many useful principles. Here we focus on several of the most relevant topics.Formalizing learning:First, let's formalize the most general machine
