Meta-Learning Approaches for a One-Shot Collective-Decision Aggregation: Correctly Choosing how to Choose Correctly

no code implementations3 Apr 2022 Hilla Shinitzky, Yuval Shahar, Ortal Parpara, Michal Ezrets, Raz Klein

In addition, we offer a new aggregation method, the Devil's-Advocate aggregator, to deal with cases in which standard aggregation methods are predicted to fail.

Exploiting Meta-Cognitive Features for a Machine-Learning-Based One-Shot Group-Decision Aggregation

no code implementations20 Jan 2022 Hilla Shinitzky, Yuval Shahar, Dan Avraham, Yizhak Vaisman, Yakir Tsizer, Yaniv Leedon

To evaluate our methodology, we collected 2490 responses for different tasks, which we used for feature engineering and for the training of ML models.

Implementation and Evaluation of a Multivariate Abstraction-Based, Interval-Based Dynamic Time-Warping Method as a Similarity Measure for Longitudinal Medical Records

no code implementations18 May 2021 Yuval Shahar, Matan Lion

Tasks: Classifying 161 oncology patients records as autologous or allogenic bone-marrow transplantation; classifying 125 hepatitis patients records as B or C hepatitis; predicting micro- or macro-albuminuria in the next year for 151 Type 2 diabetes patients.

A Methodology for Bi-Directional Knowledge-Based Assessment of Compliance to Continuous Application of Clinical Guidelines

no code implementations13 Mar 2021 Avner Hatsek, Yuval Shahar

Furthermore, it would be beneficial to detect such deviations in a manner proportional to the level of the deviation, and not to simply use arbitrary cut-off values.

Distributed Application of Guideline-Based Decision Support through Mobile Devices: Implementation and Evaluation

no code implementations22 Feb 2021 Erez Shalom, Ayelet Goldstein, Elior Ariel, Moshe Sheinberger, Valerie Jones, Boris Van Schooten, Yuval Shahar

We have designed and implemented a novel projection and callback (PCB) model, in which small portions of the evidence based GL procedural knowledge, adapted to the patient preferences and to their current context, are projected from a central DSS server, to a local DSS on the patient mobile device that applies that knowledge.

The Ethical Implications of Shared Medical Decision Making without Providing Adequate Computational Support to the Care Provider and to the Patient

no code implementations3 Feb 2021 Yuval Shahar

A paternalistic model endows with exaggerated power a physician who might not be aware of the patient preferences, is prone to multiple cognitive biases, and whose computational integration capability is bounded.

The Semantic Adjacency Criterion in Time Intervals Mining

no code implementations11 Jan 2021 Alexander Shknevsky, Yuval Shahar, Robert Moskovitch

Here, we define formally the semantics of three SAC variations, and compare the use of the set of pruned patterns to the use of the complete set of discovered patterns, as features for classification and prediction tasks in three different medical domains.

Temporal Pattern Discovery for Accurate Sepsis Diagnosis in ICU Patients

no code implementations6 Sep 2017 Eitam Sheetrit, Nir Nissim, Denis Klimov, Lior Fuchs, Yuval Elovici, Yuval Shahar

Sepsis is a condition caused by the body's overwhelming and life-threatening response to infection, which can lead to tissue damage, organ failure, and finally death.
