Speaker 2:What are transformers? How can they be applied to banking?
Abstract:
Recent developments in sequence transduction models have improved natural language processing and understanding capabilities. In this talk, Art describes the transformer architecture and how it can be used to understand and evaluate symbolic variables and expressions embedded in plain text. With nearly perfect accuracy, such models can read text to understand operations and operands involving addition, subtraction and multiplication of both positive and negative decimal numbers of variable digits assigned to symbolic variables. Such sequence transduction models can be used to analyze financial reports, flagging suspicious or erroneous content. https://arxiv.org/abs/1812.02825
