Hello to all
Artificial intelligence is often mentioned as an area where corporations make large investments. It seems that they use AI in autonomous vehicles, face recognition, medicine, banking, financing, weather forecast, etc.
The celebrated backpropagation algorithm has wide use within academic circles. Many papers exist that discuss, analyze and apply BP. But is it actually used in any of the practical developments undertaken by large companies? If so, in which specific ones. If not, which is the preferred NN training method for these commercially oriented applications?
With cordial regards,
Daniel Crespin
It seems backpropagation is used in SAS, a traditional commercial software.

Thanks very much Eduardo for the link to the SAS backpropagation package. There is no question that the SAS software uses BP in the sense that it provides language and underlying machine code to train NNs.
But I want to know if there is some outstanding practical use of BP in applied artificial intelligence. In the particular case of the SAS BP, has it been employed to train a NN that is presently used in an important task?
For example, at academic and research levels there has been much activity on reliable computer systems that detect cancer in a mammography. My question would then be if some system that effectively performs this detection has been developed by means of BP and is today in actual clinical use.
There is the face recognition problem for which artificial intelligence seems to be presently used. Are their algorithms based on BP training of NNs? Perhaps they only require appropriate use of a data basis plus traditional statistical tools.
With cordial regards,

Yes, there are a considerable number of practical applications. You may, for instance, examine the following article:
