Give a description of the basic rules that you should follow when making a good data flow map.
If you could provide us with any background information on how to design dependable data input fields, we would greatly appreciate it. There may be instances when deviating from these guidelines is required, but under what conditions?
Mt noy Modify the Octave script that you wrote for Task 1 to generate the
following figure. It may look difficult at first, but if you really understand the code
that you wrote for Task 1, it shouldn't be that difficult to generate the figure
below.

- What exactly is the meaning of input data validation?arrow_forwardYou can use the selection structures in this chapter interchangeably for many circumstances. There are a few occasions when one is clearly preferable to another based on input data. Some of these situations were touched on in the switch statement discussion. Review these, give an overview of all of the selection structures discussed in the chapter, and then discuss how to determine which structure to use when there is no clear indication. How much of the choice should be based on personal preference and how much on conventional practices? Are there performance issues as well?arrow_forwardState whether the following statement is true or false. ‘Feature engineering is applied in the very initial stages of the data science projects while model tuning comes at the end of the project where we want to inch-up the model performance.’arrow_forward
