Reviewer 2 Report
1) What is the importance of the hypothesis |c(t)|\neq 0 in page 1?
2) The main background of this paper is not clear. Please kindly clarify the main background of this paper in the revision. The English should be improved throughout the whole paper and also the introduction part of the paper should be improved. This recent work could be mentioned : Convergence analysis on time scales for HOBAM neural networks in the Stepanov-like weighted pseudo almost automorphic space. Neural Computing and Applications, 1-15 (2020)
3) These results are there applicable for the environments investigated in the above paper (pseudo almost periodic, pseudo almost automorphic, etc...)?
4) The simulations of the numerical example, should be added.
