4 Algorithms We Borrowed from Nature

The video explores how algorithms inspired by nature enhance technology. It covers Nearest Neighbors search and Locality Sensitive Hashing for image searches, fly brain-inspired hashing for improved accuracy, and convolutional neural networks based on cat brain research for computer vision. Anomaly detection is likened to the immune system's negative selection, and swarm intelligence is compared to termite behavior for decentralized coordination. These nature-inspired algorithms demonstrate how natural phenomena can inform and improve computational methods.
