In this paper we present a simple and computationally efficient quantization scheme that enables us to reduce the resolution of the parameters of a neural network from 32-bit floating point values to 8-bit integer values. The proposed quantization scheme leads to significant memory savings and enables the use of optimized hardware instructions for integer… (More)
Query expansion for Information Retrieval is a challenging task. On the one hand, low quality expansion may hurt either recall, due to vocabulary mismatch, or precision, due to topic drift, and therefore reduce user satisfaction. On the other hand, utilizing a large number of expansion terms for a query may easily lead to resource consumption overhead. As… (More)
Fifty one patients with systemic lupus erythematous were examined using magnetic resonance angiography (MRA) to determine cerebral hemodynamic features. A comprehensive study revealed different cerebral circulatory changes in this abnormality.
