KAIST said a mechanical engineering team has developed core control technology that allows a quadruped robot to choose and switch in real time among walking, running and jumping. The team used simulation to generate 15.5 hours of training data in 8 minutes and applied reinforcement learning so the robot could select gaits on complex terrain. Tests on the KAIST Hound included indoor courses, campus areas and forest paths, with a peak speed of 6 metres per second on rough ground.

KT launched its \"public sector AI email security\" service after obtaining the Cloud Security Assurance Program (CSAP) certification from the Korea Internet & Security Agency (KISA), the company said on Sunday. The cloud-based service uses AI to detect and block email-borne threats such as ransomware and phishing. It applies a three-stage filtering system, supports optional APT analysis engines and maintains more than 97 percent detection accuracy, KT said.
