Corona Likelihood Metric (CLM)

COVID-19 Self Risk-Assessment App

What is CLM?

Corona Likelihood Metric (CLM) is a self-screening application powered by machine learning technology. CLM will assist you in measuring the risk of the possibility of COVID-19 and recommend what you need to do

CLM is not replacing SIKM as the permit
to travel in/out Jakarta Province

How Does CLM Machine Learning Work?

The process of modeling CLM machine begins with data preprocessing, namely by cleaning the existing data so that it is ready to be studied by our machine learning model.

We then build multiple versions of the machine learning model with 80% of the data at hand. We tested the performance of these models using several criteria, namely accuracy, precision, and sensitivity using 20% of the testing data.

The best-performing model is then evaluated for this CLM engine, which can be used by the public to find out more about the risk percentage of COVID-19.

For the record, this machine is continuously monitored and updated using the latest data from the Jakarta Department of Health.

Risk Assessment in CLM

Three types of data are used as the reference for calculating CLM

Demographic conditions

(age, sex)

History of COVID-19 symptoms

(in the last 14 days)

Patient history

(travel, contacts, health facilities visitation, and if someone is a health workers)

The CLM machine learning model is also trained with the medical history data of thousands of patients who were examined and identified with COVID-19 by the Jakarta Health Department
