Prototype smart office collects 200+ sensors over 36 rooms for ~3.5 months via MQTT → Kinesis Firehose → S3, sensors emit on change so timestamps are irregular. Pipeline pivots observations to time-series, upsample to 1m then downsample to 7m to regularize gaps, then trains multi-step classifiers by framing targets as arrays and using a multi-output RandomForest for 6‑hour occupancy prediction. Automation runs on EMR via boto3 run_job_flow with bootstrap pip installs, parallelizing per room and persisting models and predictions to DynamoDB.
