The objective effect is the same

    Hi @AP,

    The relative options guarantees a certain proportion of the input dataset on output. For example, with 100 examples and a sample ratio of 0.5, I will get 50 examples on output. The probability option instead assigns a probability to each example of it being included in the sample, so you could get in theory and value between 0 and 100. In practice it will likely fall between 50 plus of minus a couple of standard deviations.

    Hope this helps.

    Best,

    Roland
