>There were expert systems that worked well and they became profitable businesses, but othervice there was little to show. One could similarly say about our time: "there were neural network applications that worked well, but otherwise there was little to show". What is the fundamental difference between what is going on now and what was happening before the previous AI winter? I feel that people constantly misrepresent how impressive expert systems seemed back in their heyday. They had a lot of practical applications and they could do some very cool tricks. Interestingly, the highly impressive accomplishments of SVMs, random forests and boosting went mostly unnoticed, precisely because of the AI Winter.
