Sometimes you hear that deep learning only works when lots of data is available, it's partly true, still there are a few method we can use get a nice mode with samll amount of data. "Too few data": a few thousand to tens of thousand. We now develop a cat/dog classification convnet...
Build and apply a deep neural network to supervised learning. Let's get started! 1 - Packages Let's first import all the packages that you will need during this assignment. numpyis the fundamental package for scientific computing with Python. ...
Using the same template as we did before, here are five steps to run this classification. 使用与之前相同的模板,下面是执行此分类的五个步骤。 1.Dataset:Load the data set, do some feature engineering if needed.2.Build Model:Build a TensorFlow model with various layers.3.Compile Model:Here we...
于是想到了《Deep Learning with Python》,忘记这本书怎么来的了,但是在别的地方看到了有人推荐,说是Keras的作者写的非常好的一本入门书,翻了前面几十页后发现居然跟进去了,不该讲的地方没讲比如数学细节,而且思路也极其统一,从头贯穿到尾(比如representations, latent space, hypothesis space),我觉得很受用。

in the RG format, whereas “make the image less saturated” is simpler in the HSV format. Machine-learning models are all about finding appropriate representations for their input data—transformations of the data that make it more amenable to the task at hand, such as a classification task. ...
