OpenAI releases “not fully reliable” tool to detect AI generated content

ChatGPT has been creating waves across the internet with its writing ability and responses to requests. The use of ChatGPT has been full of     1     . There have been concerns that students can use this tool to     2     AI-generated work and claim it as their own.

OpenAI, the research laboratory behind ChatGPT, has released a tool designed to     3     whether text has been written by artificial intelligence, but warns it’s not completely reliable – yet. In a blog post on Tuesday, OpenAI linked to a new     4     tool that has been trained to distinguish between text written by a human and that written by a variety of AI, not just ChatGPT.

The tool could be useful in cases where AI was used for “    5     dishonesty” and when AI chatbots were positioned as humans, they said. But they admitted the tool “is not fully reliable” and only correctly identified 26% of AI-written English texts. It also incorrectly     6     human-written texts as probably written by AI tools 9% of the time.

“Our classifier’s reliability     7     improves as the length of the input text increases. Compared to our     8     released classifier, this new classifier is significantly more reliable on text from more recent AI systems.”

Since ChatGPT was opened up to public    9    , it has given rise to a wave of concern among educational institutions across the world that it could lead to cheating in exams or assessments. Lecturers in the UK are being urged to review the way in which their courses were     10    , while some universities have banned the technology entirely and returned to pen-and-paper exams to stop students using AI.

Are You Scared of AI?

A recent Monmouth University survey has found that only 9 percent of Americans believe that computers with artificial intelligence will do more good than harm to society. When the same survey was conducted 35 years ago, about one in five said AI would benefit mankind. In other words, people have less complete     1     in AI now than they did dozens of years ago, when the technology was more science fiction than reality.

“It’s     2     that there is public doubt about AI. There absolutely should be,” said Meredith Broussard, an artificial intelligence researcher and professor at New York University. Most Americans     3     agree with Broussard that AI has a place in our lives, but not for everything.

When asked questions about     4     in which AI might be used, most people said it was a bad idea to use AI for military aircraft that try to distinguish between enemies and civilians. Some are worried about the     5     use of AI in policing, disturbing people’s privacy. Most respondents said it was a good idea for machines to perform risky jobs such as coal mining.

The term “AI” is a catch-all for everything. It can be the constant use of technology, such as our daily preference to autocomplete in web search queries (关键词). It can also be the software that     6     to predict crime before it happens. People afraid of AI may be influenced by     7     of evil computers from books and movies — like Skynet, the super-intelligent machines in “The Terminator” movies. Broussard said the ways AI can end up destroying your quality of life won’t be as     8     as murderous fictional computers.

Actually, the fear of AI     9     due to the fact that we just don’t know where AI is going and how soon it will take us to get there. Technology makes surprising and unusual leaps and     10     in ways we never think it will. Anyway, whether we like it or not, artificial intelligence is here to stay.

An entirely new art form is developing. This art form goes beyond     1     giving viewers one thing to look at. Instead, it surrounds them with images and sounds. This usually takes the form of rooms where music plays and images are     2     onto walls, changing when visitors interact with them. Sometimes pleasant smells are added to draw people in through yet another sense. These rooms are known as immersive (沉浸式的) exhibits because they seek to involve viewers completely.

The most famous company     3     immersive exhibits is called teamLab. What this company does is draw on people with a huge range of skill sets: artists, engineers,     4     and even mathematicians. All of these skills are necessary to produce the complex immersive exhibits teamLab is known for. Much of the company’s art is based on nature. This is a(n)     5     choice as their goal is to help people feel more connected to the rest of the world. This goal reflects some traditional Asian philosophies, which makes sense because teamLab is a Japanese company. TeamLab’s philosophy states that it seeks to transcend (超越) the     6     that people have set up to separate them from other things.

Other companies are also developing immersive exhibitions     7     at providing entertainment, education or both. For example, American company Imagine Exhibitions has designed over 40 exhibitions, which combine art, lighting, textures, scents and more. Physical objects are carefully selected and placed throughout the exhibits to add to their realism. The topics of their exhibits     8     from the history of ancient Egypt to nature to TV shows and games such as Angry Birds.

Immersive exhibits maybe a new development, but they are     9     by older art forms. Some immersive exhibits are even apparently about the work of artists who worked in other media, such as the painter Vincent van Gogh. Even those who do not reference other artists so clearly are often influenced by older art styles. And many of the immersive exhibits also     10     some form of music.

By combining skills and technologies in creative ways, teams are developing new ways for people to experience art.

Animal Communication

Many pet owners long to talk with their animals. After all, if pets were able to talk, people could take care of them more easily and have closer emotional     1     to them, so a number of companies are working on devices and apps that could translate what animals say.

One such app is called MeowTalk. Using voice recognition software, this app recognizes different sounds a cat makes and offers English translations of them. For example, one type of sound might mean “feed me” while another could be translated “let me outside.” The app can use machine learning to assess its translations and improve at recognizing one particular cat’s voice. In other words, it can     2     in understanding your cat in particular. This is important because cats do not all have a(n)     3     language, but individual cats frequently use particular sounds to mean certain things.

In the future, MeowTalk could connect to a smart collar that would hear the cat meow and play the translation out loud. Perhaps if the cat is outside and needs to be let in, it could even send     4     to the owner’s phone.

For dogs, a Japanese company called Inupathy has developed a harness (保护带) with a heart rate monitor and an app. The heart rate monitor is used to assess a dog’s     5    . This is possible because, like humans, dogs’ heart rates go up when they are excited or     6    . The harness also has a light that turns red when the dog is excited, but when the dog is relaxed, the light is blue.

The most obvious use of this technology is to help pet owners     7     with and provide for their pets better. The more owners know about their pets, the easier it is to meet their needs.

There are other     8     of technology that help us understand animals. For example, some sheep farmers are using artificial intelligence to scan and determine if they are in pain, which helps them find out sick animals. As a result, they can     9     more quickly to treat the animal.

Anyone who interacts regularly with animals could benefit from understanding their animals better. Thus these     10     developments might transform the way we interact with the creatures around us.

Lego: One Step Closer to Being Sustainable

The Lego Group is one step closer to reaching its goal of making all its products from sustainable materials by 2030.

The Danish toymaker revealed a prototype (雏形) brick made from     1     plastic. In a news release, Lego said the PET plastic from     2     bottles makes up the first brick to meet the company’s “strict quality and safety requirements.” One way the company     3     safety is by sourcing materials from suppliers that use processes approved by the US Food & Drug Administration and European Food Safety Authority.

“The biggest     4     on our sustainability journey is rethinking and innovating new materials that are as long-lasting, strong and high quality as our existing bricks—and fit with LEGO elements made over the past 60 years,” Lego Group Vice President of Environmental Responsibility Tim Brooks said. “With this prototype we’re able to    5     the progress we’re making to the public.”

It will be “some time” before bricks made from used materials can be     6    , Lego said. The company will continue to test and develop the PET formulation (配方) and decide whether to move to the     7     production phase, which is expected to take at least a year. One factor the company is testing is how the material can be     8    .

“Experimentation and failing is an important part of learning and     9    . Just as kids build, unbuild and rebuild with LEGO bricks at home, we’re doing the same in our lab,” Brooks said.

The move follows last year’s announcement that the company was making a $400 million investment over three years into sustainability     10    . It included phasing out the single-use plastic bags from its boxes and instead using recyclable paper for its packaging.

Plant-based Milk

There are nutritional differences between types of milk, from oat to soy to cow’s. Plant-based milks have been growing in     1     for years, but the nutritional content of different milks and milk alternatives vary, with disagreements between brands too. The global dairy alternatives market is     2     to grow from $22.25 billion in 2021 to $53.97 billion in 2028, according to a report by Fortune Business Insights. In February 2022, the world’s first potato milk launched in the UK, which bills itself as “the most     3     plant-based dairy alternative on the market.”

While some people choose dairy alternatives, cow’s milk is an excellent     4     of calcium, protein, and vitamin D. It’s also working better than water when people feel thirsty, according to a small study by St Andrews University in Scotland. However, some people stay away from dairy because of intolerance of the mouthfeel or environmental concerns, and for some, the     5     factor is health. Nutritional reports of milks vary, with some offering more fiber, fat, protein, carbs, sugar, and calories than others.

Dietitians recommend choosing fortified plant-based milks. Plant-based milks are not     6     “healthier” than dairy, and when following a plant-based diet, dietitians recommend ensuring your dairy-free milk alternatives are fortified with essential vitamins and minerals. “Fortified means that they are added by the manufacturer and so will be on the ingredients list, or advertised on the front,” dietitian Nichola Ludlam-Raine     7     told Insider.

“Choose milk alternatives that are fortified with vitamins such as vitamin B12 and vitamin D, in addition to the minerals calcium and iodine,” she said. The     8     content of milk varies in terms of protein, carbs, and fiber. Cow’s milk, for example, contains lots of calcium and vitamin D, as well as protein. Soy milk is often fortified with calcium, and is also high in protein. For the purpose of this     9    , Insider selected popular brands of each milk, selecting     10     options wherever possible, per cup. Here’s some nutritional information on our website to bear in mind when choosing which milk to have in your coffee, on your cereal, or alongside a cookie.

How the Victorians Invented the “ Staycation ”

Holidays feel like an important refreshment after such a tough year. While international travel is possible, it’s not exactly easy, so many are choosing to stay closer to home, taking a “staycation ”. This year holidaymakers are discovering the     1     of the UK’s coast and the beauty of its landscapes.

Domestic tourism as we know it began in the 19th century when the idea of the holiday was just becoming     2     . Expanding railways and changing work practices meant people had more leisure time for travelling. International travel was becoming easier but wasn’t     3     to all, so the Victorians chose to spend this newfound “ free ” time in the UK.

This gave way to the     4     of hot new holiday destinations, mostly on the UK’s coast. Great British seaside towns, from Bournemouth to Brighton, appealed to people with     5     of fun, sea and clean air — many of the things that continue to attract people today.

The great summer holiday as we know it was designed by the Victorians. The 19th century saw the industrial     6     and the rise of industrial capitalism, where factories were booming and work structures were more clearly and severely defined and presented. This led to the emergence of administrative     7     , like clerks, and an emerging middle class.

There was more     8     working time, including shift work in factories and time off on Sundays. As a result, working-class people had leisure time to use, and by the 1890s some skilled workers had half days on Saturdays, leading to the birth of the “ weekend ” — though this was not     9     until much later in the 20th century.

In 1871 the Bank Holidays Act was passed. This appointed certain days as holidays on which banks closed, though, over the years, more businesses began observing these days off work. Before 1830, banks closed only on the 40 saints’ days of the year, though by 1834 this was just four days, including Christmas day. From 1871, any day could be     10     a bank holiday, not just saints’ days.

Heartbreak: Romantic Metaphor(比喻) or Serious Health Condition

It is an unfortunate fact of life that most of us will experience the sensation commonly known as “heartbreak” at some point in our lifetime. Heartbreak refers to feelings of extreme sadness, often persistent, due to a(n)     1     disturbing event. The term “heartbreak” or “broken heart” is usually used in a symbolic sense.

That is, when we say someone is “heartbroken,” we do not mean that their heart has actually     2    . However, what many people do not know is that so-called broken heart syndrome(综合症), often caused by stress, is a recognized     3     health condition.

Much like when people make metaphorical     4     to heartbreak, broken heart syndrome is also caused by painful life events. These experiences usually     5     death, divorce, or separation. However, this condition can have very real negative effects on a sufferer’s health. In clinical settings, broken heart syndrome is often     6     with a heart attack because many of the symptoms of these two conditions are very similar. The main difference is   that while a heart attack is     7     by a blockage in one of the heart’s arteries(动脉), broken heart syndrome involves temporary enlargement in one area of the heart. Such enlargement makes it difficult for the heart to continue     8     blood around the body and thus puts the sufferer at risk of heart failure.

If you have experienced a stressful or painful event, two     9     symptoms of broken heart syndrome to watch out for are chest pain and breathing difficulties. In fact,     10     one or both of these symptoms can be vital in helping you seek necessary treatment in the early stages of this condition.
