Andrew NG recommends dividin

calculates the accuracy of the entire system at this time: As shown in, text recognition consists of four parts. Now we can find the system accuracy after optimization for each part. The question is, how can we improve the accuracy of the entire system? We can see from the table that, if we have optimized the text moderation part, the accuracy will be72%Add89%If we optimize the character segmentation, the accuracy is only from89%To90%If character recognition is optimized90%To100%In contr

Ai is the future, is science fiction, is part of our daily life. All the arguments are correct, just to see what you are talking about AI in the end. For example, when Google DeepMind developed the Alphago program to defeat Lee Se-dol, a professional Weiqi player in Korea, the media used terms such as AI, machine learning, and depth learning to describe DeepMind'

To draw a full stop to the first four sessions of the course, here are two of the models that were mentioned in the first four lectures by Andrew the Great God.The Perceptron Learning Algorithm Sensing machineModel:From the model, the Perceptron is very similar to the logistic regression, except that the G function of logistic regression is a logical function (also called the sigmoid function), which is a continuous curve from the Y value of 0 to 1.
