Suppose your classifier obtains a training set error of 0.5%, and a dev set error of 7%. In the intro to this post, it is mentioned that “Clearly, a lot of people start the test without understanding Deep Learning, which is not the case with other skill tests.” I would like to know where I can find the other skill tests in questions. 21) [True or False] BackPropogation cannot be applied when using pooling layers. Indeed I would be interested to check the fields covered by these skill tests. But in output layer, we want a finite range of values. Look at the below model architecture, we have added a new Dropout layer between the input (or visible layer) and the first hidden layer. BackPropogation can be applied on pooling layers too. You missed on the real time test, but can read this article to find out how many could have answered correctly. Deep Learning - 328622 Practice Tests 2019, Deep Learning technical Practice questions, Deep Learning tutorials practice questions and explanations. Slide it over the entire input matrix with a stride of 2 and you will get option (1) as the answer. So to represent this concept in code, what we do is, we define an input layer which has the sole purpose as a “pass through” layer which takes the input and passes it to the next layer. Course 4 of Advanced Machine Learning, Practical Reinforcement Learning, is harder than Course 1, Introduction to Deep Learning. 98% train . A) Overfitting they're used to log you in.

The size of weights between any layer 1 and layer 2 Is given by [nodes in layer 1 X nodes in layer 2]. D) All of the above. All of the above methods can approximate any function. As all the weights of the neural network model are same, so all the neurons will try to do the same thing and the model will never converge. On the other hand, if all the weights are zero; the neural neural network may never learn to perform the task.
