In our thirties, we jokingly call it brain freeze. In our forties, we laugh it off as a senior moment and follow up with one of these old age jokes. But the reality is that there es a point when being forgetful stops being funny and starts to seem a bit dreadful. You think, Am I losing it？Or worse, Is this a sign of Alzheimer39。 Well, don39。s disease（AD）. The researchers in a new study show that it39。re forgetful that we should fear.s disease is a damaged awareness of illness. And they wanted to prove their theory that the lack of awareness can be used to predict whether someone with mild cognitive（認(rèn)知的）damage will progress to fullon AD. For the study, mild cognitive damage was defined as someone whose mental state was considered healthy but who had either plained of memory loss or had suffered objective memory loss.People can be forgetful at different ages.B.Old people are most afraid of getting Alzheimer39。It39。Being aware all the time is a fearful thing.B.s disease.C.t mean developing Alzheimer39。Realizing forgetfulness must be a sign of developing Alzheimer39。s disease?

A branch of AI known as deep learning, which uses neural(神經(jīng)的) networks to scan through large volumes of data looking for patterns, has proven so useful that skilled practitioners can mand high sixfigure salaries to build software for Amazon, Apple, Facebook and Google.s top universities. Earning one takes years and requires a personality suited to academia, which is rare among more normal folk. Last month , a nonprofit education organization based in San Francisco, kicked off the third year of its course in deep learning. Since its foundation it has attracted more than 100, 000 students around the globe from India to Nigeria. The course and others like it, e with a simple idea: there is no need to spend years obtaining a PhD in order to practise deep learning. Creating software that learns can be taught as a craft, not as a high intellectual pursuit to be undertaken only in an ivory tower. Fast. ai39。 To make it accessible to anyone who wants to learn how to build AI software is the aim of Jeremy Howard, who founded with Rachel Thomas, a mathematician. He says school mathematics is sufficient. No. Greek.
