08:43 < Suryo> Hello zoq! As a first implementation, would it be okay to have a simple lbest pso? I was wondering if the pso and gradient descent hybrid should be kept as a different method, as a different update policy.
08:44 < Suryo> Could you please tell me what you think?

10:11 < zoq> Suryo: Agreed, we should split the two, either by writing another policy or by writing an independent optimizer.

17:49 < favre49> Hey guys. I have been developing a differential evolution implementation, and am mostly done. However, when i run the linear regression test on it, i get the error: "Mat::init(): requested size is not compatible with column vector layout". Could you tell me why this error may be coming up?
18:01 -!- ImQ009 [~ImQ009@unaffiliated/imq009] has quit [Read error: Connection reset by peer]
18:01 < rcurtin> favre49: usually this happens if you have, e.g., an arma::vec that you're trying to set to be a matrix
18:01 < rcurtin> so the following code will cause the same problem:
18:01 < rcurtin> arma::mat x(10, 10, arma::fill::randu);
18:02 < rcurtin> arma::vec y = x;
18:02 < rcurtin> so probably this is what is happening somewhere (or something like that)
