perhaps this is very stupid of me to ask,and i’ll delete this when i get the answer what is distribution andrew keeps referring to?

Hey @ans , Are you asking about the meaning of the term? A probability distribution is a description of how likely a random variable or set of random variables is to take on each of its possible states. For example, a random variable may be a person’s age. We may represent states of such variable …

sorry my question was not clear, i was referring to distribution as in “training and test set must come from x distribution”… i think he was not using it in any technical sense,i think it was casual use of the word…

[image] ans: i was referring to distribution as in “training and test set must come from x distribution” That statement relates to the probability distribution. It means that distributions of both sets are the same. In other words, if you plot a chart for each set, as the one above, they will…

what i gathered: each picture is either from camera or from net,so if we pick dev set as camera pics,we must pick test set also from camera pics “they should come from the same distribution” as if i pic a random pic from test set and one from dev set ,the probability of them both being from the ca…
