What is one hot encoding?

For nominal data type where there is no comparison among the categories , one-hot encoding can be applied which is similar to binary coding considering there are in less number and for the ordinal data type, label encoding can be applied which is a form of integer encoding.

It means that this type of data can’t be counted or measured easily using numbers and therefore divided into categories. The gender of a person (male, female, or others) is a good example of this data type.

Why is data encoding important in machine learning?

Data encoding for Qualitative data is important because machine learning models can’t handle these values directly and needed to be converted to numerical types as the models are mathematical in nature.

Why is it important to have all the cases explicitly defined in the type?

One important consequence of having all the cases explicitly defined in the type is that the compiler can ensure you did not forget any case when writing your function. This prevents a common kind of error— missing edge cases—without any additional work on your part.

What character field to use for lookup table?

I would use a short (10 or less) character field and fk it to a lookup table to control what values can be entered.

Is algebraic data recursive?

Algebraic data types can also be recursive, letting us encode data structures like lists and trees. For example, the type for a binary tree with values at its leaves looks like this:

It’s hard to imagine a typed language without some notion of product. It’s probably the simplest and most fundamental way to build bigger abstractions out of smaller ones—just put them together!

Can a project be male/female?

Depends on what you need, likely your project specifies whatever is required. It can be a classic male/female, it can be male/female/other, male/female/unspecified and so on. It can also be a n:m mapping with a list of possible choices to support the different definitions that are used sometimes.

Is there a datatype for ismale?

As far as I know, there is no datatype. Assuming you understand there are only two, you could use a bit field called “isMale”, or “isFemale” if you prefer. 1 would be as the name implies, 0 would be the other gender. If you want it to be an optional field, null for unknown/unanswered.
