Top 10 Deep Learning Interview Questions

Deep Learning has become the buzz in today's job market. With AI and Machine Learning becoming increasingly prevalent in our day-to-day lives, organizations of all types are looking for personnel with the knowledge and expertise to help them reap the benefits of this revolutionary technology.

With the increasing demand for professionals who can use algorithms and data sets to create more effective and accurate models, it has become essential for job seekers to demonstrate their proficiency in this area during interviews. 

The first step to landing your dream job is clearing the interview round. In this article, we will go through the top Deep Learning interview questions for experienced that can help you land a job.

Before we go into the interview questions on Deep Learning, let us define deep learning.

Deep Learning – What is it?

Deep learning is a powerful machine learning technique that enables computers to learn by example. This technology has become integral to the development of driverless cars, allowing them to identify street signs, people, and other objects. Similarly, it is the foundation of voice control in consumer products like phones, speakers, and televisions. Deep learning has gained significant attention in recent years due to its ability to deliver accurate results. 

When using deep learning, computer models are trained to recognize patterns and categories from images, text, or sound. This training enables the model to achieve unparalleled accuracy, often surpassing human-level performance. To create these models, large datasets with labels are used alongside complex neural network architectures that contain multiple layers.

Top 10 Deep Learning Interview Questions You Need to Know Now

Here is a list of some of the top questions you may be asked in an interview: 

  • What is the purpose of Deep Learning in today's world, and how does it benefit data scientists? 

Answer: Deep learning has transformed machine learning and data science unprecedentedly. At the forefront of this revolution is the complex neural network (CNN), which has become the go-to for data scientists due to its impressive capabilities. Deep learning provides the added benefit of deciphering and simplifying matters based on an algorithm, owing to its malleable and adjustable nature. 

Its unique ability to allow data to move in independent pathways makes it a rare and powerful tool. Data scientists now view deep learning as a cutting-edge, extended approach to traditional machine learning, allowing them to address and solve even the most intricate issues. 

  • How can neural networks be used to train hyperparameters? 

Answer: The four components indicated below can be used to train hyperparameters:

  • Batch size: This specifies the size of the input chunk. Depending on the requirements, batch sizes can be changed and sub-batched.
  • Epochs: An epoch is the number of times the neural network sees the training data to train. Because the procedure is iterative, the number of epochs varies depending on the data.
  • Momentum: Momentum is utilized to comprehend the subsequent actions with the present data being executed. It is used in training to avoid oscillations.
  • Learning rate: The learning rate is a parameter that indicates how long it takes the network to change the parameters and learn. 
  • How Do Feedforward Neural Networks and Recurrent Neural Networks Differ? 

Answer: A Feedforward Neural Network operates with signals that only flow in a single direction from the input to the output. Consequently, it cannot remember past inputs, thus making it unsuitable for tasks such as Convolutional Neural Networks (CNNs). 

On the other hand, a Recurrent Neural Network's signals flow in both directions, forming a looped network. This allows the network to not only process the current input but also take into account previously received inputs when generating the output of a layer, thus allowing the network to remember past data. 

  • What do you understand by Multilayer Perceptron (MLP)? 

Answer: MLPs are a type of neural network that consists of an input layer, one or more hidden layers, and an output layer. Unlike single-layer perceptrons, MLPs are capable of perceptions classifying non-linear classes rather than just linear separable classes with binary output (0, 1). 

Each node in the hidden layers uses a nonlinear activation function, so the data coming in and the output are based on the weights being added together in the input layer. MLP is then trained using a supervised learning method called “backpropagation," which uses a cost function to calculate the error and propagate the error back to adjust the weights, thus training the model more accurately. 

  • How many layers are there in the neural network? 

Answer: There are three sorts of layers in a neural network. 

  • The Input Layer: The input layer comprises neurons that send data to the hidden layer. 
  • Hidden Layer: The hidden layer sends data to the output layer. 
  • The Output Layer: The data is made available in the output layer. 
  • Can you distinguish between AI, Machine Learning, and Deep Learning? 

Answer: Artificial Intelligence is a revolutionary technology that enables machines to act and think like humans. 

Machine Learning builds upon this concept, using statistical methods to make machines more efficient through experience. 

Deep Learning takes this step further, utilizing multi-layered neural networks to make complex decisions like humans. 

  • What precisely are data visualization libraries? 

Answer: Data visualization libraries make complex concepts easier to comprehend by utilizing visual components like graphs, diagrams, maps, etc. These visualization programs enable you to identify patterns, trends, and outliers and transform your data according to your specifications. The most popular data visualization libraries are D3, React-Vis, Chart.js, vx, and more. 

  • Define Backpropagation 

Answer: Backpropagation is a training technique used in multilayer neural networks. It sends fault information from the network's end to all weights inside the network. It enables efficient gradient computing.

Backpropagation is broken down into the following steps:

  • It can backward propagate the results of the training data through the network to reach the input 
  • It utilizes the targeted value and output value to compute error derivatives concerning the output activations 
  • It can backpropagate to compute the derivative of the error with output activations in the prior layer and continue for all hidden layers. 
  • It uses the already determined derivatives for output and all hidden layers to find the error derivative to weights. 
  • It adjusts the weights accordingly. 
  • What is the purpose of activation? 

Answer: The activation function is responsible for converting inputs to outputs. By determining the weighted total and then applying the bias, the activation function determines whether or not a neuron should be activated. The goal of the activation function is to introduce nonlinearity into the output of a neuron.

There are several activation functions, such as: 

  • Linear or Identity
  • Binary unit or step 
  • Tanh 
  • ReLU 
  • Softmax 
  • Tanh or Logistic 
  • Explain overfitting 

Answer: Overfitting occurs when a model is too closely tailored to the data points it created and cannot accurately predict future observations or incorporate new data. This modeling error is common in large datasets containing some anomalies, resulting in inaccurate analysis. To avoid overfitting, the model should have fewer parameters than the data can accommodate.

Finally, with the knowledge acquired from these Deep Learning coding interview questions, you can confidently answer and make a great impression on the interviewer.

Conclusion

Deep Learning is an emerging field rapidly changing how businesses and organizations use data. As a deep learning expert, knowing the answers to these top 10 questions is essential for success in an interview.
