The Idiap Research Institute is an independent, non-profit research foundation specializing in multimedia information management and in multimodal man-machine interaction.
The story follows the customer experience of a mobile wallet user. The level of security through biometric authentication increases with the amount of the transaction (no authentication for a soda, face authentication for a 40-Euros purchase, face and voice authentications for a cash withdrawal or a purchase above 100 Euros)
WFSTs represent a means of pre-compiling the grammars used by ASR decoders. Such pre-compiled grammars tend to lead to both quicker decoding, because duplication of weights and paths is minimised, and simpler decoder implementations, because the composition process is offline. Pre-compiled grammars are quite large, sometimes limited only by the size of the memory on the host CPU.
Data-flow is a signal processing paradigm where modular components can be arranged in directed graphs to perform complex tasks. Data-flow lends itself to block calculations that take advantage of the hierarchical caches on modern CPUs. It also naturally modularises flow-based algorithms such that the components are easily re-used.
