Between the rolled eyes, shrugged shoulders, jazzed hands and warbling vocal inflection, it’s not hard to tell when someone’s being sarcastic as they’re giving you the business face to face. Online, however, you’re going to need that SpongeBob meme and a liberal application of the shift key to get your contradictory point across. Lucky for us netizens, DARPA’s Information Innovation Office (I2O) has collaborated with researchers from the University of Central Florida to develop a deep learning AI capable of understanding written sarcasm with a startling degree of accuracy.

“With the high velocity and volume of social media data, companies rely on tools to analyze data and to provide customer service. These tools perform tasks such as content management, sentiment analysis, and extraction of relevant messages for the company’s customer service representatives to respond to,” UCF Adjunct Professor of Industrial Engineering and Management Systems, Ivan Garibay, told Engadget via email. “However, these tools lack the sophistication to decipher more nuanced forms of language such as sarcasm or humor, in which the meaning of a message is not always obvious and explicit. This imposes an extra burden on the social media team, which is already inundated with customer messages to identify these messages and respond appropriately.”

As they explain in a study published in the journal, Entropy, Garibay and UCF PhD student Ramya Akula have built “an interpretable deep learning model using multi-head self-attention and gated recurrent units. The multi-head self-attention module aids in identifying crucial sarcastic cue-words from the input, and the recurrent units learn long-range dependencies between these cue-words to better classify the input text.”

In the welding field, however, some argue that a robot takeover might be beneficial, and even necessary.

Columbus startup Path Robotics believes AI is one solution to the shortage of skilled labor that plagues welding. Path boasts the “world’s first truly autonomous robotic welding system.” Conceived after 18 months in the basement of a foundry, its system identifies what needs to be welded, welds it and learns along the way.

Path Robotics CEO Andy Lonsberry said he and his brother, Alex Lonsberry, chief technology officer at Path Robotics, always wanted to start a business.

Adopting edge technologies will be key to businesses’ success, according to chip giant Intel.

What is really going on with Virgin Galactic, Get the inside scoop from the initial developer of the engine technology who worked for Burt Rutan on SpaceShipOne and also worked SpaceShipTwo-Tim Pickens, See why he, and I are concerned about Virgin Galactic.
Tim Pickens is an entrepreneur, inventor, innovator, engineer and educator. He specializes in commercial space, technical product development and solutions, and business consulting and strategy for space and technical companies. He is known for applying a lean philosophy to develop creative solutions and innovative partnerships to provide responsive, low-cost products and services for government and private industry. Pickens’ 25+ years of experience in the aerospace industry, specializing in the design, fabrication and testing of propulsion hardware systems, has earned him a reputation as one of the industry’s leaders in these areas. Early in his career, Pickens served as propulsion lead for Scaled Composites on SpaceShipOne, winner of the $10 million Ansari X Prize. He also worked for small hardware-rich aerospace companies in Huntsville, and later supported the Virgin Galactic’s SpaceShipTwo venture.

Cryptocurrency mining operators, including a Huobi Mall and BTC.TOP, are suspending their China operations after Beijing stepped up its efforts to crack down on bitcoin mining and trading, sending the digital currency tumbling.

Cryptocurrency miners, including HashCow and BTC.TOP, have halted their China operations after Beijing intensified a crackdown on bitcoin mining and trading, hammering digital currencies amid heightened global regulatory scrutiny of them.

A State Council committee led by Vice Premier Liu He announced the crackdown late on Friday — the first time the council has targeted virtual currency mining, a big business in China that accounts for as much as 70% of the world’s crypto supply. read more

Technology around space travel is accelerating at a rapid pace. As a result, we may soon see a future where one doesn’t need to be an astronaut to travel the stars. But there’s a long line of legal and safety logistics to be met before we can all start booking our personal space voyages.

The rise of AI has been accompanied by an explosion of processing horsepower.

News, analysis and comment from the Financial Times, the worldʼs leading global business publication.

Early in the testing phase of Apple’s M1 chipset, a milestone new product for the company, the processor was installed in a batch of Mac computers and given to staffers working on applications that demanded heavy processing power. It was a pivotal moment: the first time Apple had made its own chip for any of its computers, shifting away from years of using a one-size-fits-all option from Intel.

After multiple teams tested the devices for a few hours while working on tasks, they reported lightning-fast performance but nearly all flagged an apparent problem. The MacBook Pro’s battery indicator, featured on the upper right hand corner of the computers, was broken. It had barely moved despite running power-hungry programs, the company told CNN Business.

The gag, of course, is that the battery indicator was working just fine. The M1 chip was so efficient, according to Apple, that it showed no real strain — one of several major selling points for products that now carry the chip. (Apple promises 20 hours of battery life for its 13-inch M1 MacBook Pro — what it says is the longest battery in any Mac to date).

There’s some really interesting CRISPR news out today, and it’s likely to be a forerunner of much more news to come. A research team has demonstrated what looks like robust, long-lasting effects in a primate model after one injection of the CRISPR enzymatic machinery. There have been plenty of rodent reports on various forms of CRISPR, and there are some human trials underway, but these is the first primate numbers that I’m aware of.

The gene they chose to inactivate is PCSK9, which has been a hot topic in drug discovery for some years now. It’s a target validated by several converging lines of evidence from the human population (see the “History” section of that first link). People with overactive PCSK9 have high LDL lipoproteins and cholesterol, and people with mutations that make it inactive have extremely low LDL and seem to be protected from a lot of cardiovascular disease. There are several drugs and drug candidates out there targeting the protein, as well there might be.

It’s a good proof-of-concept, then, because we know exactly what the effects of turning down the expression of active PCSK9 should look like. It’s also got the major advantage of being mostly a liver target – as I’ve mentioned several times on the blog already, many therapies aimed at gene editing or RNA manipulation have a pharmacokinetic complication. The formulations used to get such agents intact into the body (and in a form that they can penetrate cells) tend to get combed out pretty thoroughly by the liver – which after all, is (among other things) in the business of policing the bloodstream for weird, unrecognized stuff that is then targeted for demolition by hepatocytes. Your entire bloodstream goes sluicing through the liver constantly; you’re not going to able to dodge it if your therapy is out there in the circulation. It happens to our small-molecule drugs all the time: hepatic “first pass” metabolism is almost always a factor to reckon with.
