Bootstrapping Word Alignment via Word Packing

We introduce a simple method to pack words for statistical word alignment. Our goal is to simplify the task of automatic word alignment by packing several consecutive words together when we believe they correspond to a single word in the opposite language. This is done using the word aligner itself, i.e. by bootstrapping on its output. We evaluate the performance of our approach on a Chinese-to...

Optimizing modality operations.

A successful imaging outcome for a patient requires that each step of the workflow, from examination request to timely communication of actionable information, be optimized in order to deliver maximal quality, safety, and patient satisfaction. This series uses the concept of the imaging value chain to understand how this can best be achieved. The prior article discussed imaging protocol optimiz...

Optimizing Kernel Block Memory Operations

This paper investigates the performance of block memory operations in the operating system, including memory copies, page zeroing, interprocess communication, and networking. The performance of these common operating system operations is highly dependent on the cache state and future use pattern of the data, and no single routine maximizes performance in all situations. Current systems use a st...

Optimizing floating point operations in Scheme

It is well known that dynamic typing in languages like Lisp is costly in terms of performance. Besides the cost of tag checking, the other major source of ine ciency comes from the need to place and retrieve data from dynamically allocated objects, i.e. boxing and unboxing. This makes it unacceptable in general to write numerical code in Lisp. Such programs involve \tight" loops in which boxing...
