I have only a few remarks on this paper, even though they shouldn't be considered as weaknesses. They are listed below in no particular order. - in eq.1 | is used both as the absolute value operator and the cardinality one, which can lead to confusion - in eq.2, \tau and v have not been previously defined (unless I'm missing something) - I find it regrettable that no theoretical analysis of Mesa (e.g. convergence speed, generalization error, etc) is proposed aside from the complexity one, especially since it is built upon frameworks with strong theoretical properties - line 155 "is thus can be" typo - line 173 reference error "Haarnoja et al." - line 233 compares > compared - table 2, what does k correspond to? Is it the parameter of Algorithm 2? - a few more datasets would've been appreciated, especially concerning the cross-task transferability
