Here are the Questions and Answers:
Question 1: What is Artificial intelligence? *
- Playing a game on Computer
- Making a machine Intelligent
- Programming on Machine with your Own Intelligence
- Putting your intelligence in Machine
Question 2: Who is known as the – Father of AI”? *
- Fisher Ada
- Alan Turing
- John McCarthy
- Allen Newell
Question 3: How many types of Machine Learning are there? *
- 1
- 2
- 3
- 4
Question 4: Supervised learning deals with unlabeled data, while unsupervised learning deals with labelled data. *
- True
- False
Question 5: The “Regression” technique in Machine Learning is a group of algorithms that are used for: *
- Predicting a continuous value; for example predicting the price of a house based on its characteristics.
- Prediction of class/category of a case; for example a cell is benign or malignant, or a customer will churn or not.
- Finding items/events that often co-occur; for example grocery items that are usually bought together by a customer.
Question 6: Which of the following is the meaning of “Out of Sample Accuracy” in the context of evaluation of models? *
- “Out of Sample Accuracy” is the percentage of correct predictions that the model makes on data that the model has NOT been trained on.
- “Out of Sample Accuracy” is the accuracy of an overly trained model (which may captured noise and produced a non-generalized model)
Question 7: When should we use Multiple Linear Regression? *
- When there are multiple dependent variables
- When we would like to predict impacts of changes in independent variables on a dependent variable.
- When we would like to identify the strength of the effect that the independent variables have on a dependent variable.
Question 8: Which of the following examples is/are a sample application of Logistic Regression? (Select all that apply) *
- The probability that a person has a heart attack within a specified time period using person’s age and sex.
- Customer’s propensity to purchase a product or halt a subscription in marketing applications.
- Likelihood of a homeowner defaulting on a mortgage.
- Estimating the blood pressure of a patient based on her symptoms and biographical data.
Question 9: Which one is TRUE about the kNN algorithm? *
- kNN is a classification algorithm that takes a bunch of unlabelled points and uses them to learn how to label other points.
- kNN algorithm can be used to estimate values for a continuous target.
- None of the above
Question 10: What is “information gain” in decision trees? *
- It is the information that can decrease the level of certainty after splitting in each node.
- It is the entropy of a tree before split minus weighted entropy after split by an attribute.
- It is the amount of information disorder, or the amount of randomness in each node.
Question 11: Which of the following is an application of clustering? *
- Customer churn prediction
- Price estimation
- Customer segmentation
- Sales prediction
Question 12: Which approach can be used to calculate dissimilarity of objects in clustering? *
- Minkowski distance
- Euclidian distance
- Cosine similarity
- All of the above
Question 13: How is a center point (centroid) picked for each cluster in k-means? *
- We can randomly choose some observations out of the data set and use these observations as the initial means.
- We can create some random points as centroids of the clusters.
- We can select it through correlation analysis.
Question 14: What is a “Memory-based” recommender system? *
- In memory based approach, a recommender system is created using machine learning techniques such as regression, clustering, classification, etc.
- In memory based approach, we use the entire user-item dataset to generate a recommendation system.
- In memory based approach, a model of users is developed in attempt to learn their preferences.
- All of the above
Question 15: What is the shortcoming of content-based recommender systems? *
- As it is based on similarity among items and users, it is not easy to find the neighbour users.
- It needs to find similar group of users, so suffers from drops in performance, simply due to growth in the similarity computation.
- Users will only get recommendations related to their preferences in their profile, and recommender engine may never recommend any item with other characteristics.
Question 16: Which of the following are applications of deep learning? *
- Color Restoration in Greyscale Images
- Self-Driving Cars
- Automatic Machine Translation
- Automatic Handwriting Generation
- All of the Above
Question 17: An artificial neural network can be composed of which of the following types of layers? *
- Output Layer
- Hidden Layer
- Sparse Layer
- Input Layer
- Intermediate Layer
Question 18: A artificial neuron is so powerful that it can perform complex tasks by simply performing a linear combination of its inputs. *
- True
- False
Question 19: The weights and biases in a neural network are optimized using: *
- Activation Descent
- Activation Function
- Vanishing Gradient
- Gradient Descent
- Logistic Descent
Question 20: The popularity of self-driving cars has been rising at an exponential rate over the past decade. Based upon what you have learned, which of the following computer vision technique(s) is useful for self-driving cars? Select all relevant answers *
- Object Detection
- Motion Transfer
