The continuous/tracking/predictive AF modes of Canon’s EOS (D)SLR cameras were famously called "AI Servo" and "AI Focus", terms coined somewhere in the late 80s I believe. The early implementations were simple dead-reckoning-based control systems, hardly "AI" even by the standards of that time.

Slightly ironically, now in the mirrorless era, and AF algorithms actually based on DL subject recognition and complex predictive algorithms, Canon has retired the "AI" label.
