1. In the podcast they mention " commercial APIs" for gender classification using computer vision. What is an example of a company offering such a service? (You will have to google to find it) 2. Here is a quote from the podcast "in both, MLP and computer vision, there tends to be a focus on precision, recall" Why could a machine learning model have high precision and accuracy overall, yet still be biased? Explain in your own words.

1. Microsoft is an example. 2. Several types of bias could still be present in MLP and computer vision, even if such a model has high precision and accuracy. For example, a machine learning model could have automation bias, in which the results generated by the model are favored even though a non-automated system might have even higher precision and recall rates. Another example of biases that could be present in machine learning models is selection and coverage bias: the data used to train the model might not be reflective of the frequency that such data exists in the real world, or the training data might not be similar enough to the data that the machine learning model is going to be used for.

You need to save some unseen data points for model evaluation and testing b. The ROC curve is better when using only 9 months of data. c. The other three months where not relevant to the business model. d. The training will be too slow if using all 12 months of data.

The internet is the standard communication channel that APIs use to transmit requests and responses between programs. The client-server model is the underlying architecture that web-based APIs use for exchanging information. The ________ is a computing device (e.g. a smartphone, laptop, etc.) that makes a request for some computing resource or data. The request needs to be formatted in the agreed upon protocol. The ________ has data and/or computing resources stored on it. Its job is to interpret and fulfill requests.

Which of the following is true concerning Deployment Manager? a. Templates can be written in XML or YAML b. Deployment manager is only used for building virtual machines c. Deployment manager is an imperative tool d. Deployment manager is a declarative tool

d. Deployment manager is a declarative tool explanation: can be written with YAML only

EXAMPLE: A sentiment-analysis model is trained to predict whether book reviews are positive or negative based on a corpus of user submissions to a popular website. The majority of reviews in the training data set reflect extreme opinions (reviewers who either loved or hated a book), because people were less likely to submit a review of a book if they did not respond to it strongly. As a result, the model is less able to correctly predict sentiment of reviews that use more subtle language to describe a book. Is this an example of bias in ML? If yes, what kind? If no, why not? a. Yes. Automation Bias. b. No. This is an example of lack of stationarity in the dataset. c. No. This is an example of overfitting. d. Yes. Reporting Bias.

d. Yes. Reporting Bias.

What is the difference between a single and double hashtag in a markdown cell? A) Double hashtag is title header, single hashtag is a smaller header B) There is no difference C) Single hashtag is title header, double hashtag is a smaller header

Every GCP service you use is associated with a project. Which of the following statements regarding projects are correct? A) Projects have a single owner. B) A project cannot be restored once deleted. C) Projects are billed and managed collectively. D) Projects are the basis for enabling and using GCP services. E) Each project is a separate account, and each resource belongs to exactly one.

D) Projects are the basis for enabling and using GCP services. E) Each project is a separate account, and each resource belongs to exactly one. Feedback: Projects are the basis for enabling and using GCP services, like managing APIs, enabling billing, adding and removing collaborators, and enabling other Google services. Each project is a separate account, and each resource belongs to exactly one. Projects can have different owners and users. They're billed separately, and they're managed separately.
