In this paper, we investigate the properties of commonly used prepruning heuristics for rule learning by visualizing them in PN-space. PN-space is a variant of ROC-space, which is particularly suited for visualizing the behavior of rule learning and its heuristics. On the one hand, we think that our results lead to a better understanding of the effects of stopping and filtering criteria, and he...

prior to the implementation of co2 injection eor projects, the screening evaluation of candidate reservoirs will promote the economic benefits of co2 injection. currently, a uniform screening method for co2 miscible flooding does not exist. based on more than 112 successfully implemented co2 miscible flooding reservoirs, which was referred in 2010 worldwide eor survey, and co2 miscible flooding...

In light of the NSF’s commitment to measuring performance and results, there was strong support for undertaking a proper evaluation of the PFI program. The preceding chapters reported on a number of specific outcome measures and process measures (signposts) that were suggested to assess program performance; we now turn to some of the broader principles that were articulated (or could be inferre...

In this work, we determined the measure to compare and evaluate the performance of lip detection techniques. Despite of a number of methods used for lip-detecction/localization, a reliable method for comparing and determining the quality of the result is still missing. The proposed criterion ensures the clear and fair way to report the results so that mentioned results can be comparable and mea...

Description Logic Programs (DLP) is an expressive but tractable subset of OWL. In this paper, we study a rising but under-researched problem of learning DLP from uncertain data. Current research rarely explores the plentiful uncertain data populating the Semantic Web. We handle uncertain data in Inductive Logic Programming (ILP) framework by modifying the performance evaluation criteria. We ado...

UNLABELLED Background : The impact of the RECIST 1.1 on the selection of target lesions and assessment of tumor response was not evaluated in patients with advanced NSCLC who received cytotoxic chemotherapy. METHODS We reviewed medical records of patients with advanced NSCLC who received first-line chemotherapy between January 2004 and December 2013 and compared the selection of target lesion...

The formal evaluation of social welfare programs has imposed stringent demands upon research methodologies in economics and other social sciences. Often the validity of the performance criteria must be reassessed. We now know, for instance, that simply counting numbers served or dollars spent provides insufficient information. The Institute was closely associated with the development of target ...

We consider how machine learning can be used to help solve the problem of identifying objects or structures composed of parts in complex scenes. We first discuss a conditional rule generation technique (CRG) that is designed to describe structures using part attributes and their relations. We then show how the resultant rules can be used for region labeling and examine constraint propagation te...

higher education plays a very vital role in developing human resources as well as economic ones in every country. in so doing, the act of evaluation would help the decision makers as well as managers to spot the weaknesses to use the required provisions to work more effectively. the present study with a different approach toward the designing a comprehensive evaluation expert system using fuzzy...
