Industry regulations, government laws, and compliance policies determine the importance of various data types and determine what and how data can be processed, stored, managed, or shared.

Question 21

Is my data high quality?

Answer 21

Data used in an ML project should be:

Relevant: Produce valuable results
Fresh: Timely so that training data is as close to the actual data as possible
Representative: Reflect data across all data sources
Unbiased: Ensure fair representation

Question 22

Is my data relevant for the type of machine learning project I intend to build?

Answer 22

Example: If you are developing a machine learning solution for a forecasting model, but you don’t have data directly related to that goal, the data will not help you power the model. For any potentially relevant data, keep it on the list and assess its suitability.

The machine learning lifecycle consists of nine stages, and the entire process typically takes weeks or even months to complete.

Question 29

Will my machine learning model change over time?

Answer 29

Yes, the model may need to change over time. To maintain accuracy, the data distribution on which predictions are made should match the distribution of the training data. Since data distributions can drift, deploying a model is an ongoing process that requires continuous monitoring and retraining to adapt to new data.

Question 30

What is a best-case timeline for a machine learning project?

Answer 30

Even in the best-case scenario, deploying production models can still take weeks or months. A common misconception is that most of the time is spent in the Modeling, Training, and Testing stages; however, the overall timeline includes additional phases that contribute to the total duration.

Question 35

How do I take my machine learning solution into production?

Answer 35

While production deployment of an ML model is one of the final stages of the ML pipeline, it’s important to note that production code differs significantly from research code. Research code is primarily for exploration and model validation, often lacking formal quality, stability, or scaling requirements. In contrast, production code must meet fixed requirements, facilitate collaboration through version control, maintain a code deployment history, and adhere to code reliability standards.

Question 36

What is the likely computational cost of generating predictions with your model?

Answer 36

Understanding the computational cost associated with generating predictions is crucial. This includes storage, processing, and other related expenses. Planning for these costs in advance can help avoid obstacles during production deployment and ensure that the model meets business requirements efficiently.

Question 37
