Challenge: Detect Faulty Sensors with Clustering
In engineering systems, sensor data is crucial for monitoring equipment and ensuring reliable operation. However, sensors can sometimes fail or provide inaccurate readings, which may lead to incorrect assessments or even system failures. Clustering algorithms, such as KMeans, are powerful tools for automatically grouping similar data points and identifying anomalies. By clustering sensor readings, you can detect groups of normal behavior and flag data points that deviate significantly from their cluster centers. These outliers are often indicative of faulty sensors or abnormal system conditions. In this challenge, you will use KMeans clustering to separate normal and abnormal temperature readings from multiple sensors and identify which sensors are likely malfunctioning based on their distance from the cluster centers.

Given a list of temperature readings from multiple sensors, your task is to use KMeans clustering to group the readings and identify which sensors are likely faulty. This challenge builds on your understanding of clustering and anomaly detection in engineering data.
- Use KMeans clustering with
n_clusters=2to group thetemperature_readings. - Assign each reading to a cluster and determine the cluster centers.
- Identify the cluster with the fewest members (the minority cluster).
- Return a tuple containing the list of cluster assignments and the list of indices for the readings assigned to the minority cluster (suspected faulty sensors).
