“It’s very useful for neural nets and artificial intelligence in general,” said Soumith Chintala, a research engineer at Facebook AI Research, Facebook’s lab for advanced computing.
Torch is also useful in computer vision, or the recognition of objects in the physical world, as well as question answering systems. Mr. Chintala said his group had fed a machine a simplified version of “LOTR” novels and the computer can understand and answer basic questions about the book.
The company said on Friday that for public use it was donating several powerful tools for computers, including the means to go through huge amounts of data and looking for common elements of information. The products, used in a so-called neural network of machines, can speed pattern recognition by up to 23.5 times, Facebook said. It’s very early, but it shows incredible promise,” he said. Facebook can already look at some sentences, he said, and figure out what kind of hashtag should be associated with the words, which could be useful in better understanding of people’s intentions. Such techniques could also be used in determining the intention behind an Internet search, something Google does not do on its regular search.(source: nytimes)
