An ML framework is any tool, interface, or library that lets you develop ML models easily. Which are benefits of using a framework for your machine learning project? Pre-made collection of resources. Provides a way to document your code. Can help you do things faster. Ensures your models are highly accurate.9. ######QUESTION#########If we assume that all Canadians also speak French, what type of bias might this be?Sampling BiasGroup Attribution BiasAutomation Bias10. ######QUESTION#########Which of the following is NOT a reason cloud computing is often used for machine learning today?Cloud computing allows for quick access to sophisticated equipment.The distributed nature of cloud computing allows for less expensive model development.Cloud providers have made available easy access to many machine learning services without the need to create whole models from scratch.11. ######QUESTION#########Which one of these is not a common machine learning programming language?JuliaRJupyter Notebook12. ######QUESTION#########As a ML engineer , John got requirement to deliver ML framework.He has got few ML frameworks option to choose.Which of these is a very popular machine learning framework?ScalaPyTorchPython13. ######QUESTION#########Which best describes Concept Drift?The profile of the underlying ground truth data used in your model training had changed over time.Your machine learning model has gotten better over time.The performance of your machine learning model has increased as computing power gets cheaper.14. ######QUESTION#########Which statement is accurate about architecting for the cloud versus in-house landscapes?Hybrid architectures are only advisable when cloud computing costs are more than in-house costs.Architecting for the cloud is a discipline itself with its own best practices and complexities.Architecting a cloud solution is no different than architecting an in-house solution.15. ######QUESTION#########You conduct a survey via your website to ask what type of blog articles people most want. Your normal traffic is 100 visitors a day but you receive 4 responses. What type of bias might be present here?Sampling BiasSymbolic BiasParticipation Bias16. ######QUESTION#########A project member insists that we keep training our model until it produces 100% perfect results in testing. What risk might this introduce?OverfittingImplicit BiasOver-planning17. ######QUESTION#########Which is an example of online validation? (Choose 2) Creating a copy of the production database and running the model through the historical data. Running the model as a shadow deployment for a couple weeks. Testing the model using the QA version of the database rather than the production version. Deploying an A/B test for your new model.18. ######QUESTION#########If I were to assume that all dogs bark because that's what I've always been told, what type of bias might this be?Experimenter's BiasImplicit BiasConvenience Bias19. ######QUESTION#########Which of the following would most impact how you framed an ML problem? You will need to scale some values in the data using a normalization method.You discover the data you intend to use was stolen from a competitor.You realize the data is in metric units but your model intends to produce output in imperial units.20. ######QUESTION#########Which best describes A/B Testing? (Choose 2) For a period of time, we're going to be running two customer databases and manually syncing records between them until we can upgrade the other portions of our eCommerce site. Because our inventory and accounting systems are very tightly coupled, we will be upgrading both systems over the holiday weekend. Because our order processing system is loosely coupled with our inventory system, we will be temporarily queueing orders over the weekend as we upgrade the inventory system. Then, next weekend, we will upgrade the order processing system. We will be rolling out our new customer recommendation engine to a small percentage of customers to evaluate the results.21. ######QUESTION#########In reviewing the testing results from your new ML model, you notice that results are very consistent but that they are consistently 20% higher than they should be. What might you say about your model?High Accuracy, High PrecisionLow Accuracy, High PrecisionHigh Accuracy, Low Precision22. ######QUESTION#########What is a major economic benefit of cloud computing for businesses?Computing resources can be procured on an OpEx basis versus a CapEx basis.Cloud computing resources depreciate at a faster rate than in-house resources.Cloud computing platforms are simpler to use than in-house resources.23. ######QUESTION#########Which of the following will likely be most effective in incorporating the topic of ethics in your ML project?Conduct a Worst Case Workshop.Insist that the local newspaper runs a story on your new ML model.Implementing an Ethics Policy and requiring project members to sign it.24. ######QUESTION#########Which would you recommend to someone just starting their machine learning journey? Don't start. The less people know about ML, the better. It will just scare people.Don't embarrass yourself by asking questions until you have at least 2 years of experience.Start small and simple25. ######QUESTION#########Which best describes a requirement in our ML project charter to include some time to ensure we can show an external auditor how our model makes decisions?ConsistencyExplainabilityIntegrity26. ######QUESTION#########Which of the following might be considered under the risk heading of Interpretation?Your model consistently returns errors when the input data happens to be very high numbers.Your organization intends to disband the ML project team as soon as the model is in production.You are upset at the weather website for saying it was going to be sunny but instead it rained.27. ######QUESTION#########We decide to use a dataset that is 10 years old to evaluate student preferences for online coaching. A newer dataset is available, but it would require us to download 150 different files rather than the 1 file of the old data.. What bias might be be introducing?Automation BiasConvenience BiasCorrelation Bias28 out of 27Please fill in the comment box below. Author: CloudVikas
