(B) It is the measure of how accurately a model can identify positive classes out of all the positive classes present in the dataset.

(C) It is the measure of how accurately a model can identify true positives from all the positive predictions that it has made

(D) It is the measure of how accurately a model can identify true negatives from all the positive predictions that it has made

Answer: (C)

Explanation: Precision is the ratio of true positive and (true positive + false positive), which means that it measures, out of all the positive predicted values by a model, how precisely a model predicted the truly positive values.

Q17. What is True about bias and variance?

(A) High bias means that the model is underfitting.

(B) High variance means that the model is overfitting

(C) Bias and variance are inversely proportional to each other.

(D) All of the above

Answer: (D)

Explanation: A model with high bias is unable to capture the underlying patterns in the data and consistently underestimates or overestimates the true values, which means that the model is underfitting. A model with high variance is overly sensitive to the noise in the data and may produce vastly different results for different samples of the same data. Therefore it is important to maintain the balance of both variance and bias. As they are inversely proportional to each other, this relationship between bias and variance is often referred to as the bias-variance trade-off.

Q21. Which of the following is FALSE about Radial Basis Function Neural Network?

(A) It resembles Recurrent Neural Networks(RNNs) which have feedback loops.

(B) It uses the radial basis function as an activation function.

(C) While outputting, it considers the distance of a point with respect to the center.

(D) The output given by the Radial basis function is always an absolute value.

Answer: (A)

Explanation: Radial basis functions do not resemble RNN but are used as an artificial neural network, which takes a distance of all the points from the center rather than the weighted sum.

Q22. In which of the following situations should you NOT prefer Keras over TensorFlow?

(A) When you want to quickly build a prototype using neural networks.

(B) When you want to implement simple neural networks in your initial learning phase.

(C) When doing critical and intensive research in any field.

(D) When you want to create simple tutorials for your students and friends.

(B) Use dimensionality reduction techniques

(C) Use cross-validation technique to reduce underfitting

(D) Use data augmentation techniques to increase the amount of data used.

Answer: (D)

Explanation: Options A and B can be used to reduce overfitting in a model. Option C is just used to check if there is underfitting or overfitting in a model but cannot be used to treat the issue. Data augmentation techniques can help reduce underfitting as it produces more data, and the noise in the data can help in generalizing the model.

Q25. Which of the following is FALSE for neural networks?

(A) Artificial neurons are similar in operation to biological neurons.

(B) Training time for a neural network depends on network size.

(C) Neural networks can be simulated on conventional computers.

(D) The basic units of neural networks are neurons.

Answer: (A)

Explanation: Artificial neuron is not similar in working as compared to biological neuron since artificial neuron first takes a weighted sum of all inputs along with bias followed by applying an activation function to give the final result, whereas the working of biological neuron involves axon, synapses, etc.

Q26. Which of the following logic function cannot be implemented by a perceptron having 2 inputs?


(B) OR



Answer: (D)

Explanation: Perceptron always gives a linear decision boundary. However, for the Implementation of the XOR function, we need a non-linear decision boundary.

Q27. Inappropriate selection of learning rate value in gradient descent gives rise to:

(A) Local Minima.

(B) Oscillations.

(C) Slow convergence.

(D) All of the above.

Answer: (D)

Explanation: The learning rate decides how fast or slow our optimizer is able to achieve the global minimum. So by choosing an inappropriate value of learning rate, we may not reach the global minimum; instead, we get stuck at a local minimum and oscillate around the minimum, because of which the convergence time increases.

Top 13 Aws Interview Questions And Answers Updated For 2023

Introduction to AWS Interview Questions and Answers

The following article provides an outline for AWS Interview Questions. Amazon Web Services (AWS) is a comprehensive, on-demand cloud computing platform provided by Amazon to individuals, companies, and government organizations on a paid subscription basis. The technology provides a virtual cluster of a computer that is available all the time via the web. It provides a mix of infrastructure as a service (IaaS), platform as a service (PaaS) and packaged software as a service (SaaS) offerings, and Recovery as a Service (RaaS).

What is Cloud Computing? Types of Clouds

Public Cloud: A cloud where the third-party service providers make resources and services available to their customers via the internet. Related data and security are with the service providers’ owned infrastructure.

Private Cloud: This is almost similar features as the public cloud, but the data and services are managed by the organization or by the third party only for the customer’s organization. In this type of cloud, major control is over the infrastructure so security-related issues are minimized which makes it different from a public cloud.

Hybrid Cloud: As the name suggests Hybrid, is the combination of both private and public cloud. The decision to choose a type of cloud i.e. private or public usually depends on various parameters like the sensitivity of data and applications, industry certifications and required standards, regulations, and many more.

Understanding Different Types of Cloud Computing

IaaS stands for Infrastructure as a Service. It is the lowest level of a cloud solution and refers to cloud-based computing infrastructure as a fully outsourced service. It provides provision processing, storage, and network connectivity on demand. With the implementation of this service model, the customers can develop their own applications on these resources.

Software as a Service (SaaS), as the name suggests, here the third-party providers provide end-user applications to their customers with some administrative capability at the application level, such as the ability to create and manage their users. Basic customization is possible such as the user can use their own corporate logos, colors, etc.

Security Issues: The Biggest concerns in today’s world: The infrastructure provided by AWS cloud is designed in such a way that ensure flexibility and secure cloud network. It is a scalable and highly reliable platform that enables users to deploy applications and data quickly and securely and thus it is gaining its popularity in today’s market. Security is the major issue in cloud computing. The cloud service providers implement the best security standards and industry certifications, however, storing data and important files on external service providers always a risk.

Technical issues: One of the technical issues that are very common is that if the internet connection is offline then we will not be able to access any of the applications, server, or data from the cloud.

Not easy to switch service providers: It is usually promised that cloud will be flexible to use and integrate, however, switching cloud services is not easy.
