Predictive Top-Down Integration of Prior Knowledge during Speech Perception

Predictive top-down integration of prior knowledge during speech perception.

A striking feature of human perception is that our subjective experience depends not only on sensory information from the environment but also on our prior knowledge or expectations. The precise mechanisms by which sensory information and prior knowledge are integrated remain unclear, with longstanding disagreement concerning whether integration is strictly feedforward or whether higher-level k...

Predictive Top-Down Knowledge Improves Neural Exploratory Bottom-Up Clustering

In this paper, we explore the hypothesis that integrating symbolic top-down knowledge into text vector representations can improve neural exploratory bottom-up representations for text clustering. By extracting semantic rules from WordNet, terms with similar concepts are substituted with a more general term, the hypernym. This hypernym semantic relationship supplements the neural model in docum...

Effective Integration of Knowledge Management into the Business Starts with a Top-down Knowledge Strategy

A cornerstone in the integration of Knowledge Management (KM) in the business is the extension of the business strategy with a knowledge strategy. The Knowledge Strategy Process (KSP) at Siemens follows a top-down approach and helps the management to integrate knowledge strategy effectively in their business strategy. Furthermore, it brings the decision makers of a business unit on one table to...
