PRIM versus CART in subgroup discovery: When patience is harmful

Reads0

TLDR
Contrary to current conjectures, PRIM's performance was generally inferior to CART's, and its utility in clinical databases would increase when global information about (ordinal) variables is better put to use and when the search algorithm keeps track of alternative solutions.

Development of a clinical decision support system for antibiotic management in a hospital environment

TL;DR: The need for a multi-user perspective, both reactive and proactive behaviours, and the use of many heterogeneous knowledge sources are identified as the main requirements that differentiate this clinical scenario from a decision support point of view.

Contrasting temporal trend discovery for large healthcare databases

TL;DR: This study introduces a novel approach for exploring and comparing temporal trends within different in-patient subgroups, which is based on associated rule mining using Apriori algorithm and linear model-based recursive partitioning and demonstrates the existence of opposite trends in relation to age and sex based subgroups that would be impossible to discover using traditional trend-tracking techniques.

Identification of subgroups by risk of graft failure after paediatric renal transplantation: application of survival tree models on the ESPN/ERA-EDTA Registry

TL;DR: The tree model was demonstrated to be an accurate and attractive tool to predict graft failure for patients with specific characteristics and may aid the evaluation of individual graft prognosis and thereby the design of measures to improve graft survival in the poor prognosis groups.

A new Simplified Acute Physiology Score (SAPS II) based on a European/North American multicenter study

J R Le Gall, +2 more
- 22 Dec 1993 - 
TL;DR: The SAPS II, based on a large international sample of patients, provides an estimate of the risk of death without having to specify a primary diagnosis, and is a starting point for future evaluation of the efficiency of intensive care units.

Bump hunting in high-dimensional data

TL;DR: This paper presents a procedure directed towards this goal based on the notion of “patient” rule induction, which is contrasted with the greedy ones used by most rule induction methods, and semi-greedy Ones used by some partitioning tree techniques such as CART.

Thinking Inside the Box: A Participatory, Computer-Assisted Approach to Scenario Discovery

TL;DR: How scenario discovery appears to address several outstanding challenges faced when applying traditional scenario approaches in contentious public debates is described, and how this approach has already proved successful in several high impact policy studies is demonstrated.

Subgroup Discovery with CN2-SD

TL;DR: A subgroup discovery algorithm, CN2-SD, developed by modifying parts of the CN2 classification rule learner: its covering algorithm, search heuristic, probabilistic classification of instances, and evaluation measures, shows substantial reduction of the number of induced rules, increased rule coverage and rule significance, as well as slight improvements in terms of the area under ROC curve.

Intensive care unit length of stay: Benchmarking based on Acute Physiology and Chronic Health Evaluation (APACHE) IV.

TL;DR: The APACHE IV model provides clinically useful ICU length of stay predictions for critically ill patient groups, but its accuracy and utility are limited for individual patients.
