AI (Artificial Intelligence) can replace lots of repeated and less intelligent human works, but there are still many things that AI cannot do, Yung said.

“Recognising context is difficult for AI,” machine learning engineer Dr Bosco Yung said. He said it is hard for AI to determine the context in photos. For example, a person in a photo is upside down, so-called the mouth and eyes are in the right position but they are also upside down. “It seems like normal when people look at the person’s face when the photo is upside down, not to mention AI,” Yung said.

He said computers treat things differently. “Computers just recognise features and may not be able to tell us the photo is wrong,” Yung said. For an inverted house appears in a photo, it is an artistic design with upside down but it’s not wrong, but computers may think that is wrong since it’s inverted.

“Your brain has judgements in a few seconds,” Yung said at Hong Kong Shue Yan University, “but if you want a computer to distinguish you need to set many data”.

AI also having a problem of translation accuracy. He said people have a casual conversation with changing contexts quickly and processing thoughts all the time, but train machines like humans are difficult. “The language rules of AI is different from us, they may think that they are doing the right things,” Yung said.

He said human don’t let AI makes final decisions since it’s not 100% correct. “You have to do the fact check carefully,” said Yung, “journalists can be the final guard to judge”. People keep gaining knowledge and updating information to make sure have the right judgments.

Yung said when people plan a career need to think about will it be replaced by AI. “Do things less intelligent and repeated are risky,” he said.

Artificial intelligence means the theory and development of computer systems able to do tasks normally requiring human intelligence, such as speech recognition, visual perception, decision-making, and translation between languages.
