Empirical learning aided by weak domain knowledge in the form of feature importance

Standard hybrid learners that use domain knowledge require stronger knowledge that is hard and expensive to acquire. However, weaker domain knowledge can benefit from prior knowledge while being cost effective. Weak knowledge in the form of feature relative importance (FRI) is presented and explained. Feature relative importance is a real valued approximation of a feature’s importance provided by experts. Advantage of using this knowledge is demonstrated by IANN, a modified multilayer neural network algorithm. IANN is a very simple modification of standard neural network algorithm but attains significant performance gains. Experimental results in the field of molecular biology show higher performance over other empirical learning algorithms including standard backpropagation and support vector machines. IANN performance is even comparable to a theory refinement system KBANN that uses stronger domain knowledge. This shows Feature relative importance can improve performance of existing empirical learning algorithms significantly with minimal effort

The Importance of Broadband Provision to Knowledge Intensive Firm Location

Despite the volume of literature afforded knowledge work and innovations in information and communications technologies (ICTs), few studies have examined the importance of ICTs to knowledge industries and the impact of their availability on firm location decisions. This study will evaluate the relative importance of ICTs to knowledge intensive firm location for select US metropolitan statistical areas (MSAs). Spatial econometric estimation techniques are used to construct models from ZIP code level data that describe the relative importance of broadband to knowledge intensive industries, as defined in this study. A global model is constructed for all relevant ZIP code areas across the continental U.S and the results are compared to metropolitan specific models. In addition to demonstrating variations by metropolitan area in the relative importance of broadband provision, the results suggest that broadband deployment initiatives will have varied outcomes on knowledge intensive firm growth and the subsequent change in the industrial composition of regional economies in future years.

The Importance of Broadband Provision to Knowledge Intensive Firm Location

Despite the volume of literature afforded knowledge work and innovations in information and communications technologies (ICTs), few studies have examined the importance of ICTs to firms in knowledge industries. This study will develop spatial econometric models to examine the relative importance of the level of broadband provision to knowledge intensive firms in select U.S.  metropolitan statistical areas (MSAs). Results demonstrate the need for both a spatial econometric and a metropolitan area specific evaluation of this relationship. They also suggest potential spillover effects to knowledge intensive firm location, which may explain why some regional economies are relatively more successful at stimulating firm growth in this increasingly important sector of the U.S economy.

The relative importance of the PMBO guide's nine knowledge areas during project planning

Although A Guide to the Project Management Body of Knowledge (PMBOK® Guide)—Fourth Edition identifies nine Knowledge Areas that project managers should focus on while managing projects, it does not indicate the relative importance of each of these Knowledge Areas. However, such information can be of great significance in helping project managers determine how to use their available resources most effectively. This article investigates the relative importance of the project management Knowledge Areas used during the planning phase of a project and their impact on project success. Results presented in this article are based on a field study that involved 783 project managers from different countries and industries. The study revealed that the Knowledge Areas with the greatest impact on project success were Time, Risk, Scope, and Human Resources. However, these results have been found to be sensitive to the industry in which projects were undertaken. Differences among industries are described and discussed in the article

The Apple doesn't Fall far from the Tree: Location of Start-Ups Relative to Incumbents

New firm location decisions, relative to incumbents may be based on a choice between two types of advantages: natural advantages or those that arise from social embeddedness, the latter of which may particularly include knowledge spillovers. We analyze the relative importance of geographically bounded location factors based on data from 103 manufacturing industries across 327 West German and 111 East German districts. Our micro-geographic analysis reveals that the two parts of the country vary in their pattern of new firm location. In East Germany, only 5 percent of the industries reveal start-up localization patterns beyond what natural advantages would suggest compared to 40 percent in West Germany.entrepreneurship, location decision, natural advantages, local knowledge spillovers

Applying the Fuzzy Analytic Network Process to Establish the Relative Importance of Knowledge Sharing Barriers

Knowledge sharing (KS) is the key to creativity and innovation in any organizations. Overcoming the KS barriers has created new challenges for designing in dynamic and complex environment. There may be interrelations and interdependences among the barriers. The purpose of this paper is to present a review of literature of KS barriers and impute the relative importance of them through the fuzzy analytic network process that is a generalization of the analytical hierarchy process (AHP). It helps to prioritize the barriers to find ways to remove them to facilitate KS. The study begins with a brief description of KS barriers and the most critical ones. The FANP and its role in identifying the relative importance of KS barriers are explained. The paper, then, proposes the model for research and expected outcomes. The study suggests that the use of the FANP is appropriate to impute the relative importance of KS barriers which are intertwined and interdependent. Implications and future research are also propose

Knowledge in the air and cooperation between firms: Traditions of secrecy and the reluctant emergence of specialization in the ceramic manufacturing district of Lampang, Thailand

In the study of industrial clusters, the relative importance, and possible interrelationship, of inter-firm cooperation in production and broad knowledge transfers (both unintentional spillovers and intentional sharing) have long been disputed. To shed light on this we study ceramic tableware manufacturers in the city of Lampang, Thailand. Data consist of face-to-face interviews with principals in thirty-four manufacturers, and with representatives of supporting institutions. We find that an unwillingness to share knowledge with potential competitors retards the development of specialization in production; the outcome of efforts by various government actors and some manufacturers to change this situation is uncertain.ceramic manufacturing, knowledge, Lampang, networks, secrecy, Thailand
