Small dataset tabular data augmentation

hi everyone
i have a small tabular dataset, 75 overall samples in three groups. the groups are fairly balanced by the way. i want a method to augment my data. which method do you recommand?

What sort of data do you have?

  • Images?
  • Specific examples?

For tabular data, you need to understand how the data behaves (i.e., find the boundaries where the cases lie within). Then I would say using a formula you can create examples using a random parameter in the formula, which always has limits between the boundaries of each case!
