We describe a set of fast, tractable methods for characterizing neural responses to high-dimensional sensory stimuli using a model we refer to as the generalized quadratic model (GQM). The GQM consists of a low-rank quadratic function followed by a point nonlinearity and exponential-family noise. The quadratic function characterizes the neuron’s stimulus selectivity in terms of a set linear rec...

In planning software process improvement activities, it is essential to determine the factors that most influence the success of a software project. In this article, we present an investigative and analytical framework for evaluating software process factors based on the Goal/Question/Metric (GQM) paradigm. We built descriptive models of the software process, defects, and cost. These models wer...

The use of a single swab for both MRSA culture and for rapid testing by PCR was evaluated, using the Hain GenoQuick (GQM) methicillin resistant Staphylococcus aureus (MRSA) assay for the rapid detection of MRSA, as a single swab would be the preferred option for routine diagnostic testing. GQM detected current prevalent Irish MRSA strains incorporating all known SSCmec types, including Panton-V...

Based on GQM(Goal Question Metric) approach, this paper presents a new process-oriented metrics for software architecture adaptability. This method extends and improves the GQM method. It develops process-oriented processes for metrics modeling, introduces data and validation levels, adds structured description of metrics, and defines new indexes of metrics.

It is an important industrial need to deliver high-quality knowledge-based systems and organizational memories (e.g., to support service management or knowledge management in general). Evaluation is required to ensure this high quality and guide the development and maintenance. We present an approach for facilitating practical evaluation of organizational memories that meets the requirements fo...

Most of the software organizations face difficulties in choosing the measures to collect since there is no universal set of measures for all types of organizations and projects. Experience shows that measurement can be more successful if the measures are collected based on the goals of the organization or the project which it will serve. However, one of the major constraints for the organizatio...

Software Visualization encompasses the development and evaluation of methods for graphically representing different aspects of methods of software, including its structure, execution and evolution. Creating visualizations helps the user to better understand complex phenomena. It is also found by the software engineering community that visualization is essential and important. In order to visual...

In a competitive business landscape, large organizations such as insurance companies and banks are under high pressure to innovate, improvise and distinguish their products and services while continuing to reduce the time-to market for new product introductions. Traditional approaches to software reliability modeling for such software are black box-based. Bad structure or model again can lead u...

We consider the business process of the reversibility stage in an outsourced IT project management. We evaluate a facet of its quality: its robustness w.r.t. the risk of loosing (tacit) knowledge of the persons implied in the process. Based on the Goal-Question-Metric paradigm, we propose an approach for the definition of quality metrics covering the given operational requirements. The metrics ...

The most influential programming paradigm today is object oriented (OO) programming and it is widely used in education and industry. Recognizing the importance of equipping students with OO knowledge and skills, it is not surprising that most Computer Science degree programs offer OO-related courses. How do we assess whether the students have acquired the right objectoriented skills after they ...
