coursera machine learning review

randomly groups the data to the extent that training intensive accounts for 70% of the original data (this ratio can vary depending on the situation), and the test error is used as the criterion when selecting the model. The question comes from the Stanford University Machine Learning course on Coursera, which is described as follows: the size and price of the

SummaryClustering is unsupervised learning ( unsupervised learning does not rely on pre-defined classes or training instances with class tags), it classifies similar objects into the same cluster, it is observational learning, rather than example-based learning, which is somewhat like a fully automated classification.

straight line, but it does not need to be guaranteed.That is, to tolerate those error points, but we have to add the penalty function so that the more reasonable the error points, the better. In fact, in many cases, the more perfect the classification function is not during training, the better, because some data in the training function is inherently noisy. It may be wrong when the classification label is manually added, if we have learned these error points during training (

/BASIC_OPERATIONS.IPYNBPytorchSource: Https://github.com/bfortuner/pytorch-cheatsheetMathematics (Math)If you really want to learn about machine learning, then you need to lay a solid foundation for the understanding of statistics (especially probabilities), linear algebra, and calculus. I was a minor in mathematics during my undergraduate course, but I definitely need to

Find a good article on the internet, paste it directly, add some supplements and your own understanding, and count as this article. My education in the fundamentals of machine learning has mainly come from Andrew Ng's excellent Coursera course on the topic. one thing that wasn't covered in that course, though, was the topic of "Boosting" which I 've come into SS

For example, in 2005, there will be both ijcai and aaai, and the two meetings will be coordinated, this makes the time for the Cai recruitment notification a few days earlier than the aaai deadline, so that the articles selected by ijcai can be sent to aaai. during the review, the PC Chair of ijcai has been urging everyone to speed up, Because aaai has been worried that the recruitment notice of ijcai will be delayed and aaai will be in troubl

After being confused by Hot Spot's messy and changing parameters, I decided to change things for fun. Then we found the machine learning video on Coursera. Reading a few paragraphs is quite simple, so I recorded them in itouch and checked them out from time to time. The day before yesterday, I finally finished eating it. The content is really easy to understand.

I browsed some of the machine learning blogs of Daniel and summarized the typical contents as follows: 1. Book Reading Notes 2. Paper Reading Notes and classification survey summary 3. Technical Note and tutorial Reading Notes 4. Summary of typical and difficult problems 5. Study Plan and study records (updated daily) 6. Monthly summary and semester Summary 7. Co
