✦ Synopsis

We write this letter to comment on the ''virtual input'' phenomenon reported by Thaler (Neural Networks, 8(1) (1995) 55-65). The author attributed the phenomenon to the network's ability to perform pattern classification and completion, and reported that pruning probability affects the number of virtual inputs observed. Our independent study of Thaler's results, however, reveals a simpler explanation of the ''virtual input'' phenomenon.
