 The **AI Anomaly Detection** system is a Python-based utility that identifies outliers in datasets using statistical principles like standard deviation. This function is essential for finding anomalous data points that deviate significantly from the dataset's normal range. The **AI Anomaly Detection** system is a Python-based utility that identifies outliers in datasets using statistical principles like standard deviation.
