What is the best step by step order for machine learning pipeline?

What is the name of the design thinking work product that contains a summary description of a particular person or role?

What is a class of machine learning problems where the algorithm is given feedback in the form of positive or negative reward in a dynamic environment?

Which two properties hold true for standardized variables (also known as z-score normalization)? (Choose two.)

When communicating technical results to business stakeholders, what are three appropriate topics to include? (Choose three.)

What are the various components that make up a time series data?

When should median value be used instead of mean value for imputing missing data?

In a hyperparameter search, whether a single model is trained or a lot of models are trained in parallel is largely determined by?

What are two hyperparameters used when building a k-means model? (Choose two.)

A neural network is composed of a first affine transformation (affine1) followed by a ReLU non-linearity, followed by a second affine transformation (affine2).

Which two explicit functions are implemented by this neural network? (Choose two.)

What is a class of machine learning problems where the algorithm builds a mathematical model from a set of data that contains both the inputs and the desired outputs?

A neural network is trained for a classification task. During training, you monitor the loss function for the train dataset and the validation dataset, along with the accuracy for the validation dataset. The goal is to get an accuracy of 95%.

From the graph, what modification would be appropriate to improve the performance of the model?

Which is a technique that automates the handling of categorical variables?

A data scientist is exploring transaction data from a chain of stores with several locations. The data includes store number, date of sale, and purchase amount.

If the data scientist wants to compare total monthly sales between stores, which two options would be good ways to aggregate the data? (Choose two.)
