Define the anomaly task
Choose whether to use supervised classification with labelled anomalies, one‑class or unsupervised scoring, and define an operational false‑alarm budget.
Detect anomalies in smart meters. Assess false alarms and misses.
Anomaly detection for smart meters aims to find unexpected energy-usage patterns, sensor faults or tampering. Real deployments require careful labelling or unsupervised scoring, time-series features, latency and memory constraints for edge devices, and monitoring to detect drift and sensor failures.

Anomaly detection for smart meters aims to find unexpected energy-usage patterns, sensor faults or tampering. Real deployments require careful labelling or unsupervised scoring, time-series features, latency and memory constraints for edge devices, and monitoring to detect drift and sensor failures.
A proposed extension: run a lightweight anomaly scorer at the edge that flags candidate events for a human operator or a central system to review. The supplied starter does not implement this extension and should not be used for live decisions without further development and validation.
Choose whether to use supervised classification with labelled anomalies, one‑class or unsupervised scoring, and define an operational false‑alarm budget.
Aggregate meter readings into windows, compute statistical and domain features (usage deltas, periodic residuals) and simulate anomalies for initial testing.
Fit a simple scorer and measure precision at fixed recall, false‑alarm rate, and latency on hold‑out time slices.
Prototype an edge runtime, add drift detection and an operator review queue to handle flagged events.
The supplied starter creates a synthetic classification dataset with sklearn.make_classification, fits a DecisionTreeClassifier, and measures repeated single‑sample prediction latency. It prints the project name, estimated latency, tree depth and node count. It does not use smart‑meter telemetry, time‑series features, unsupervised anomaly scoring, thresholding, or anomaly-specific evaluation metrics.
X, y = make_classification(n_samples=1000, n_features=12, n_informative=8, random_state=42)
model = DecisionTreeClassifier(max_depth=6, random_state=42)
model.fit(X, y)
sample = X[:1]
start = time.perf_counter()The code trains a DecisionTree on synthetic, balanced classification data from make_classification rather than modelling anomalies in meter telemetry. It lacks time‑series feature engineering, anomaly scores or thresholds, realistic anomaly examples, and any domain‑specific evaluation (for example precision at low false‑alarm rates). The single small latency loop does not validate edge deployment under realistic input shapes or streaming workloads.
A proposed extension: replace the synthetic data with windowed meter telemetry, implement an unsupervised scorer (for example isolation forest or autoencoder), tune thresholds for an acceptable false‑alarm rate, and expose flagged events to a review dashboard with provenance metadata.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
