DECEMBER 23, 2024

Traditional exact nearest neighbor search methods (e.g., brute-force search and k -nearest neighbor (kNN)) work by comparing each query against the whole dataset and provide us the best-case complexity of. We will start by setting up libraries and data preparation.

Similarly, autoencoders can be trained to reconstruct input data, and data points with high reconstruction errors can be flagged as anomalies. Proximity-Based Methods Proximity-based methods can detect anomalies based on the distance between data points. We will start by setting up libraries and data preparation.
