    Two view learning: SVM-2K, theory and practice

    Get PDF
    Kernel methods make it relatively easy to define complex highdimensional feature spaces. This raises the question of how we can identify the relevant subspaces for a particular learning task. When two views of the same phenomenon are available kernel Canonical Correlation Analysis (KCCA) has been shown to be an effective preprocessing step that can improve the performance of classification algorithms such as the Support Vector Machine (SVM). This paper takes this observation to its logical conclusion and proposes a method that combines this two stage learning (KCCA followed by SVM) into a single optimisation termed SVM-2K. We present both experimental and theoretical analysis of the approach showing encouraging results and insights

    The results of a Commodity Flow Analysis of Hazardous Materials for Interstate 64 (I-64) conducted by Western Kentucky University in partnership with the Montgomery County Local Emergency Planning Committee (LEPC) are presented within this report. This report specifically focuses on the portion of the I-64 corridor located in Montgomery County, Kentucky. Figure 1.1 shows the location of Montgomery County in relationship to the state of Kentucky. The purpose of this report is to present information regarding the patterns of hazardous materials transportation along I-64 as observed from July 14, 2014 through August 1, 2014. In addition, this report also summarizes hazardous materials incidents that have occurred over the previous ten years (January 2004-2013). Finally, the report presents and assesses survey information that was collected from fixed facilities within Montgomery County that ship and receive hazardous materials. The commodity flow analysis was necessary in order to provide the Montgomery County LEPC with information about hazardous materials transport patterns so that they can better prepare for potential incidents and releases of hazardous materials along I-64. The data collected will assist in the emergency planning process by providing valuable information about frequently observed hazardous materials within the duration of the study

    This report presents the results of a Hazardous Materials Commodity Flow Study for Daviess County, KY. Study components were conducted by Western Kentucky University in partnership with Daviess County Emergency Management Agency. The study area was focused in Daviess County and included a railway-monitoring site near Henderson, KY. A map of the Daviess County is shown in Figure 1.1. As part of this study, hazardous materials (hazmats) transported through the study area were monitored via placard surveys at the following sites: U.S. Highway 60 (Hwy 60), east and westbound lanes at East Fourth Street & the Hwy 60 Bypass (U.S. 231); U.S. Route 231 (Route 231), southbound lanes at East Fourth Street & and U.S. 231 South; William H. Natcher Parkway (Natcher Pkwy), north and southbound lanes at 4301 Plantation Pointe; Audubon Parkway, east and westbound lanes at second overpass west of Owensboro; CSX Railway (CSX), north and southbound trains monitored from Sunset Park in Henderson, KY while crossing over bridge between Kentucky and Indiana. The purpose of this report is to present information on patterns of hazardous materials commodity flow along Hwy 60, Hwy 231, Natcher Parkway, Audubon Parkway, and CSX, as observed from May 27, 2013 to August 7, 2013. This report also summarizes incidents involving hazardous materials over the previous 5 years, December 2008 to June 2013, in Daviess County

    Towards an expert system for enantioseparations: induction of rules using machine learning

    Get PDF
    A commercially available machine induction tool was used in an attempt to automate the acquisition of the knowledge needed for an expert system for enantioseparations by High Performance Liquid Chromatography using Pirkle-type chiral stationary phases (CSPs). Various rule-sets were induced that recommended particular CSP chiral selectors based on the structural features of an enantiomer pair. The results suggest that the accuracy of the optimal rule-set is 63% + or - 3% which is more than ten times greater than the accuracy that would have resulted from a random choice

    A review of expert systems for chromatography

    Get PDF
    Expert systems for chromatography are reviewed. A taxonomy is proposed that allows present (and future) expert systems in this area to be classified and facilitates an understanding of their inter-relationship. All the systems are described focusing on the reasons for their development, what their purpose was and how they were to be used. The engineering methods, knowledge representations, tools and architectures used for the systems are compared and contrasted in a discussion covering all the stages of the development life cycle of expert systems. The review reveals that too often developers of expert systems for chromatography do not justify their decisions on engineering matters and that the literature suggests that many ideas advocated by knowledge engineers are not being used

    The results of a commodity flow analysis of hazardous materials for KY Highway 21 (KY-0021) and KY Highway 627 (KY-0627) conducted by Western Kentucky University, in partnership with the Madison County Local Emergency Planning Committee (LEPC), are presented within this report. This report specifically focuses on the portions of these highways located in Madison County, Kentucky. Figure 1.1 shows the location of Madison County in relationship to the state of Kentucky. The purpose of this report is to present information regarding the patterns of hazardous materials transportation along KY-0021 and KY-0627 as observed from August 4, 2014 through August 15, 2014. This report also provides an analysis of incidents involving hazardous materials over the period of 2005 through 2014 in Madison County. Finally, this report summarizes these observations and provides recommendations based on these observations. The commodity flow analysis was necessary in order to provide the Madison County LEPC with information about hazardous materials transport patterns so that they can better prepare for potential incidents and releases of hazardous materials along KY-0021 and KY-0627. Analysis of hazmat incidents in Madison County provided an evaluation of significant hotspots where further risk assessments should be conducted. The data collected will assist in the emergency planning process by providing valuable information about frequently observed hazardous materials within the duration of the study
