Course on Deep Learning Fundamentals Answers

Module 1 :- Introduction to Deep Learning

Question 1 : Select the reason(s) for using a Deep Neural Network.
Some patterns are very complex and can’t be deciphered precisely by alternate means
Deep Nets are great at recognizing patterns and using them as building blocks in deciphering inputs
We finally have the technology – GPUs – to accelerate the training process by several folds of magnitude
All of the above

Question 2: What is TRUE about the functions of a Multi Layer Perceptron?
The first neural nets that were born out of the need to address the inaccuracy of an early classifier, the perceptron.
It predicts which group a given set of inputs falls into.
It generates a score that determines the confidence level of the prediction.
All of above

Question 3: Why is the vanishing gradient a problem?
Training is quick if the gradient is large and slow if its small
With backprop, the gradient becomes smaller as it works back through the net
The gradient is calculated multiplying two numbers between 0 and 1
All of above.

Choice of deep net models
Ability to integrate data from multiple sources
Manage deep net models from the UI
Under the hood performance enhancements to allow for fast training and execution
Deriving the optimal hyper-parameter configuration

Question 2: What are the different aspects of a Deep Learning Library?
They are a set of pre-built functions and modules that you can call through your own programs
Usually maintained by high-performance teams and are regularly updated
Most are open source and have a large community that contribute to the code base
All of above.

Question 3: True or False: Theano, Caffe, and TensorFlow are examples of deep learning platforms.

Deep Learning Fundamentals final exam answers:-

Question 1: For supervised learning, which of the following deep nets would you choose?
Autoencoder
Deep Belief Nets
Convolutional Nets
Restricted Boltzmann Machines
Recurrent Nets

Question 2: Which of the following is true with respect to the training process of a deep net?
The Cost is the difference between the net’s predicted and actual outputs.
The training process utilizes gradients which measure the rate at which the weights and biases change with respect to the cost.
The objective of the training process is to make the cost as low as possible.
The training process utilizes a technique called back-propagation.
All of above.

Question 3: True or False: With backprop, the early layers train slower than the later ones, making the early layers incapable of accurately identifying the pattern building blocks needed to decipher the full pattern.
True
False

Question 4: For image recognition, which of the following deep nets would you choose? Select all that apply.
Autoencoder
Deep Belief Nets
Convolutional Nets
Restricted Boltzmann Machines
Recurrent Nets

Question 5 : How does the Deep Belief Network (DBN) solve the vanishing gradient? Select all that apply.
It uses a stack of RBMs to determine the initial weights and biases, where the output of any RBM forms the input to the next RBM.
It uses a small labelled data set to associate patterns learned by the RBMs to classes.
It utilizes supervised fine-tuning, resulting in tweaks in weights and biases and a slight improvement in accuracy.
It quickly moves through solution states – set of weights and biases – going from one to another based on a reward.
The complete process – RBMs for pre-training and supervised fine-tuning – results in a very accurate net which trains in an acceptable time.

Question 6: True or False: To train, a DBN combines two Learning methods – supervised and unsupervised. EducationalResources

The RBM is part of the first attempt at beating the vanishing gradient and uses unlabelled data.
It improves its own accuracy through self-correction.
Its purpose is to re-create inputs and in doing so has to make decisions about which input features are more important.
It stores the relative importance of the features as weights and biases.
It predicts which group a given set of inputs falls into.

Question 9 : Which of the following statements are true about the architecture of a CNN? Select all that apply.
A CNN can only have two types of layers: CONV and RELU.
A RELU layer has to always be followed by a POOL layer.
FC layers are usually found at the end.
A CONV layer has a theoretical maximum number of filters.
A typical CNN implementation has multiple repetitions of CONV, RELU and POOL layers, with sub-repetitions.

Recurrent Nets are used for time series forecasting.
Recurrent Nets can output a sequence of values.
Recurrent Nets are trained using back-propagation.
The nodes in a recurrent nets have a classifier that activate and produce a score.

Question 12: Which of the following statements are true about training a Recurrent Net? Select all that apply.
Since RNNs use backprop, the vanishing gradient is a problem.
The number of time steps used for training has no bearing on the severity of the vanishing gradient problem.
The vanishing gradient can potentially lead to decay of information through time.
