Experiment Setup Yes We investigate the impact of the parameters λ, µ, α and β on the clustering performance for MTCMRL. For each data set, we repeat the MTCMRL method 10 times by setting one parameter to search the grid and fixing the other parameters, then compute the average Acc and NMI of all the tasks under this parameter. More specifically, we successively set one parameter to search the grid {2-2, 2-1, 20, 21, 22} by fixing λ, α = 22 and µ, β = 2-1. ... For MTCMRL, we set λ and α to search the grid {2-2, 2-1, 20, 21, 22}, µ = 2-1, β = 2-1, and we choose cosine similarity to compute the similarity matrix. ...
