Whom You Know Matters: Venture Capital Networks and Investment Performance,

by Yael Hochberg , Alexander Ljungqvist , Yang Lu , Steve Drucker , Jan Eberly , Eric Green , Yaniv Grinstein , Josh Lerner , Laura Lindsey , Max Maksimovic , Roni Michaely , Maureen O'hara , Ludo Phalippou Mitch Petersen , Jesper Sorensen , Per Strömberg Morten Sorensen , Yael Hochberg , Johnson - Journal of Finance , 2007
"... Abstract Many financial markets are characterized by strong relationships and networks, rather than arm's-length, spot-market transactions. We examine the performance consequences of this organizational choice in the context of relationships established when VCs syndicate portfolio company inv ..."

to make the concept of centrality more precise. 3 Consider the network illustrated in In graph theory, a network such as the one illustrated in 6 Networks are not static. Relationships may change, and entry to and exit from the network may change each actor's centrality. We therefore construct our

Credit Card Fraud Detection with a Neural-Network,”

by Sushmito Ghosh , Douglas L Reilly - Proc. 27th Hawaii Int‟l Conf. System Sciences: Information Systems: Decision Support and Knowledge-Based Systems, , 1994
"... Abstract Using data from a credit card issuer, a neural network based fraud detection system was trained on a large sample of labelled credit card account transactions and tested on a holdout data set that consisted of all account activity over a subsequent two-month period of time. The neural netw ..."

transactions below agreedupon amoun'ts, the credit card associations provide "stand-in" authorization in order to help reduce overall transaction traffic on the communications network. These transactions are transmitted electronically to the bank at day's end.) The FDS scoring functions

Disease Prediction Based on Prior Knowledge

by Gregor Stiglic, Igor Pernek, Peter Kokol, Zoran Obradovic
"... Increasing demand for digitalization of Electronic Health Records results in increased demand for effective data mining solutions. In this study we enhance the classical Support Vector Machine-Recursive Feature Elimination (SVM-RFE) approach to optimally estimate disease risk from hospital discharge ..."

Printed In U.SA. Prediction and Cross-Validation of Neural Networks Versus Logistic Regression: Using Hepatic Disorders as an Example

by unknown authors
"... The authors developed and cross-validated prediction models for newly diagnosed cases of liver disorders by using logistic regression and neural networks. Computerized files of health care encounters from the Fallon Community Health Plan were used to identify 1,674 subjects who had had liver-related ..."

Prediction of Parametric Value of Drinking Water of Hyderabad City by Artificial Neural Network Modeling

by Niaz A. Memon, M. A. Unar, A. K. Ansari
"... Abstract:- In order to ascertain the quality of drinking water of the city of Hyderabad one of the significant parametric values of the drinking water was predicted. Like other parameters Electrical Conductivity (EC) is also imperative. The determination of electrical conductivity provides a prompt ..."

and expedient way to measure the accessibility of electrolytes in the water. There are swayed health effects on human life through these electrolytes, like disorder of salt and water balance in infants, heart patients, individuals with high blood pressure, and renal diseases. Salty taste is one of the aesthetic

Artificial neural networks trained to detect viral and phage structural proteins

by Victor Seguritan, Nelson Alves, Michael Arnoult, Amy Raymond, Don Lorimer, Alex B. Burgin, Peter Salamon, Anca M. Segall - PLOS Computational Biology , 2012
"... Phages play critical roles in the survival and pathogenicity of their hosts, via lysogenic conversion factors, and in nutrient redistribution, via cell lysis. Analyses of phage- and viral-encoded genes in environmental samples provide insights into the physiological impact of viruses on microbial co ..."

data. We have designed a method of predicting phage structural protein sequences that uses Artificial Neural Networks (ANNs). First, we trained ANNs to classify viral structural proteins using amino acid frequency; these correctly classify a large fraction of test cases with a high degree

An Ill-identified Classification to Predict Cardiac Disease Using Data Clustering

by C. Kiruthika, S. Nirmala Sugirtha Rajini
"... The health care industry contains large amount of health care data with hidden information. This information is useful for making effective decision. For getting appropriate result from the hidden information computer based data mining techniques are used. Previously Neural Network (NN) is widely us ..."
Abstract - Add to MetaCart
. In this paper by using the patient’s medical record, an ill-defined classification is used at the early stage of the patient to diagnose the cardiac disease. Based on the result the patients are advised to keep the sensor to predict them. Cardiac disease is a disease that affects on the operation of heart

An ensemble based data fusion approach for early diagnosis of Alzheimer’s disease

by Robi Polikar A, Apostolos Topalis A, Devi Parikh A, Deborah Green B, Jennifer Frymiare B, John Kounios B, Christopher M. Clark C , 2006
"... As the number of the elderly population affected by Alzheimer’s disease (AD) rises rapidly, the need to find an accurate, inexpensive and non-intrusive diagnostic procedure that can be made available to community healthcare providers is becoming an increasingly urgent public health concern. Several ..."

Hip fracture risk and subsequent mortality among Alzheimer’s disease patients in the

by Nicole L. Baker, Michael N. Cook, H. Michael Arrighi, Roger Bullock
"... Background: hip fractures result in a significant burden to the patient, their caregivers and the health care system. Patients with Alzheimer’s disease (AD) have a higher incidence of hip fracture compared with other older people without AD, although it is not clear if AD is an independent risk fact ..."

BLIND SOURCE SEPARATION AND SPARSE BUMP MODELLING OF TIME FREQUENCY REPRESENTATION OF EEG SIGNALS: NEW TOOLS FOR EARLY DETECTION OF ALZHEIMER’S DISEASE

by François Vialatte, Andrzej Cichocki, Gerard Dreyfus, Toshimitsu Musha, Tomasz M. Rutkowski, Rémi Gervais
"... The early detection of Alzheimer’s disease (AD) is an important challenge. In this paper, we propose a novel method for early detection of AD using only electroencephalographic (EEG) recordings for patients with Mild Cognitive Impairment (MCI) without any clinical symptoms of the disease who later d ..."
