of epsilon items! If the epsilon value is too low, the data after the whitening will appear to be noisy; Conversely, if the epsilon value is too high, the albino data will be too blurry compared to the original data.Epsilon method of selection:A. Draw the eigenvalues of the data graphically; b. Select a characteristic value that is larger than most of the noise in the data to reflect the epsilon .2. How to adjust the epsilon specifically? I don't know, if I had a exercise, I'd be fine.2. When p

Mnist is an entry-level computer-vision dataset that contains 60,000 training data and 10,000 test data. Each sample is a variety of handwritten digital pictures below: It also contains the corresponding label for each picture, telling us this is a number. For example, the above four pictures are labeled 5,0,4,1. Mnist's official website: http://yann.lecun.com/exdb/mnist/ You can view the current maximum record for the project: http://rodrigob.github.io/are_we_there_yet/build/classification_dat

Artificial intelligence consists of a very wide range of sciences, consisting of a variety of fields, such as machine learning, computer vision, and so on, in general, one of the main goals of AI research is to make machines capable of doing complex work that normally requires human intelligence. But different times, different people's understanding of this "complex work" is different. In Dece

assumptions, as I said, in general, deep learning is only applicable to big data, if the amount of data is small and due to deep learning parameters will lead to overfitting, so the small data recommended rules, Or try to reduce the parameters.
