Deep Learning: A Critical Appraisal.

Although has historical roots going back decades, neither the term deep learning nor the approach was popular just over five years ago, when the field was reignited by papers such as Krizhevsky, Sutskever and Hintonu0027s now classic (2012) network model of Imagenet. What has the field discovered in the five subsequent years? Against a background of considerable progress in areas such as speech recognition, image recognition, and game playing, and considerable enthusiasm in the popular press, I present ten concerns for learning, and suggest that must be supplemented by other techniques if we are to reach artificial general intelligence.
