Anomaly Detection in High-Frequency Data: A train on tracks in front of a large screen displaying a graph with red and blue lines, conveying an anomaly detection theme for high-frequency data. The train is black with yellow accents and has a round front end, indicating it may be a toy or model. It sits on black metal tracks that curve slightly to the right. In the background, a large screen dominates the scene, displaying a graph with red and blue lines against a dark blue backdrop. The graph's x-axis features small white text in a foreign language, while the y-axis is marked by larger white numbers. A few other objects are visible on the left side of the image, but they are out of focus and indistinguishable.
