![]() ![]() Siri has been designed to assist with mundane tasks, such as checking online reviews to find a good local restaurant and booking a table. Intelligent appĪ spin-off of DARPA’s project, an app called Siri, will be coming to Apple’s iPhone later this year. For example, if a person consistently marks emails from one person, perhaps their boss, as high-priority, CALO can use that knowledge to order their meeting schedule too. So the developers have built in tricks such as “transfer learning”, which applies lessons from one domain to another. If it takes thousands of examples to learn how someone likes their email sorted, frustrated users will soon switch it off. But CALO needs to be quicker on the uptake. Most software capable of learning needs large numbers of examples for something to stick – a spam filter trained on millions of emails, for example. That focus could make the crucial difference between CALO being an annoyance like Clippy, and a genuinely useful helper. The biggest priority has been on making CALO capable of “learning in the wild,” says Raymond Perrault of SRI International, the independent Californian research organisation that led the project. It ends this Friday and has produced a virtual assistant that can sort, prioritise, and summarise email automatically schedule meetings and prepare briefing notes before them. Begun in 2003 the CALO, for Cognitive Assistant that Learns and Organizes, project involved over 60 universities and research organisations and is the largest ever non-classified AI project. ![]()
