I am a math student who has previously done a handful of regression analyses. But now I'm sitting with a classification problem and it's my first time. I wanted to know the best practices when working on a classification project.

Just like in regression it is common to fit a simple additive regression model, then with interactions, and then with non-linear expansions. After these initial steps, you can go further with more complex regression models such as ridge, lasso, random forests and so on.

Which model should I start with and which models should I try afterwards when working with classification?

FYI: I have a dataset about soil types. The response variable is soil type which has 10 different categories (sandy soil, slit soil, clay soil, ...). My task is to classify new data into these 10 different soil types from 8 other explanatory variables (deepness into the soil, hardness, ...) which are both continuous and categorical variables.

I also wanted to ask If anyone could recommend literature on classification which is math-heavy.

  • $\begingroup$ So your goal is prediction? Maths will not help you here, many ML models work... because they work. $\endgroup$ Commented Dec 20, 2022 at 11:05
  • $\begingroup$ No, I have a training and test data set, the test data set doesn't have the response variable column, so I have to classify each data point into one of the 10 soil types. I am curious how you see this as a prediction problem. Btw I totally disagree, ML doesn't always work - those ML models that do work, works only because of the math behind it work. $\endgroup$ Commented Dec 20, 2022 at 12:35

  • $\begingroup$ I cant see why my post is similar to the others, I am asking on literature regarding classification that is heavy in math - I haven't been able to find any - many of the books only covers simple introductory math on classification. Furthermore, my main question was to help me to know best practices when it comes to classification and specific to my dataset. $\endgroup$ Commented Dec 20, 2022 at 17:57
