Topic #: 6
[All AIP-210 Questions]

Given a feature set with rows that contain missing continuous values, and assuming the data is normally distributed, what is the best way to fill in these missing features?

Show Suggested Answer Hide Answer
Suggested Answer: B

A support-vector machine (SVM) is a supervised learning algorithm that can be used for classification or regression problems. An SVM tries to find an optimal hyperplane that separates the data into different categories or classes. However, sometimes the data is not linearly separable, meaning there is no straight line or plane that can separate them. In such cases, a polynomial kernel can help improve the prediction of the SVM by transforming the data into a higher-dimensional space where it becomes linearly separable. A polynomial kernel is a function that computes the similarity between two data points using a polynomial function of their features.

I've got a brilliant idea - why not just fill in the missing values with the average of the entire dataset, and then add a random number to it? That way, it'll be like a surprise every time!

User 1: That's an interesting idea, but wouldn't adding a random number introduce noise into the data?

Ah, the age-old dilemma of missing data. Deleting rows or columns seems a bit drastic, but I suppose if you're feeling brave, you could always roll the dice and see what happens.

B is a terrible idea. Filling in with random values? That's just asking for trouble. Might as well flip a coin while you're at it.

C) Fill in missing features with the average of observed values for that feature in the entire dataset.

D? Are you kidding me? Deleting entire columns with missing data is way too extreme. That's like throwing the baby out with the bathwater.

C is the way to go! Filling in with the average of observed values makes the most sense when dealing with a normal distribution.

I think deleting entire rows with missing features is too drastic, filling in with the average is more reasonable.

I agree, filling in with the average of observed values is the best approach.

I think filling in missing features with random values for that feature in the training set could introduce bias, so I would go with option C.

I disagree, I believe we should delete entire rows that contain any missing features.
