Often a patent will include background information to assist the reader in understanding the claimed invention. The text will usually also point out the shortcomings of prior inventions and how the present invention is an improvement. Neither of those are part of the invention being claimed. To understand the scope of what is claimed, you always need to look at the claims. The claims will always specifically point out the scope of the invention. Note that all elements in a claim are necessary. If an accused infringer's activity is missing an element, then it does not infringe. I think that if you look at the claims of the patent you reference, you'll find that the claims are limited to particular applications of sequence processing using particular neural network configurations.
