Samsung Electronics Co. is joining the race to create the smartest digital assistant by acquiring Viv, a Silicon Valley start-up launched by the same entrepreneurs who sold Siri to Apple. The deal announced Wednesday provides Samsung with technology to compete against Google Inc., Amazon.com Inc., Microsoft Corp. and Apple Inc. in the increasingly important field of programming computers to learn and respond as if they were human. The specialty, also known as artificial intelligence, has hatched a flock of voice-activated digital concierges -- such as Siri, Amazon's Alexa, Microsoft's Cortana and Google's Assistant -- that work in personal computers, smartphones and Internet-connected speakers. Samsung plans to implant Viv into phones, televisions and a wide range of other devices. The South Korean company did not disclose how much it paid for the start-up.

The Burbank Police Department has suspended officer deployments based on "predictive policing" technology hailed by top brass as the future of crime-fighting after complaints from police officers. The shift comes as police departments across the country are increasingly using computer technology to help predict crime trends and deploy officers accordingly. Some law enforcement agencies have said the system has helped crack down on crime. But in Burbank, critics said the software's algorithm couldn't beat a veteran officer's intuition and knowledge of his or her patrol area. They also said the algorithm sometimes zeroed in on obvious areas where officers already know there's crime or silly locations, such as the police station, where people often show up to report crimes.
