Computer science researchers at the University of Central Florida have developed a sarcasm detector.

Social media has become a dominant form of communication for individuals, and for companies looking to market and sell their products and services. Properly understanding and responding to customer feedback on Twitter, Facebook and other social media platforms is critical for success, but it is incredibly labor intensive.

That’s where sentiment analysis comes in. The term refers to the automated process of identifying the emotion—either positive, negative or neutral—associated with text. While artificial intelligence refers to logical data analysis and response, sentiment analysis is akin to correctly identifying emotional communication. A UCF team developed a technique that accurately detects sarcasm in social media text.

The team’s findings were recently published in the journal Entropy.

“Emotion recognition” might be too strong a term. More like pain recognition

BY Tristan Greene

A researcher at Wageningen University & Research recently published a pre-print article detailing a system by which facial recognition AI could be used to identify and measure the emotional state of farm animals. If you’re imagining a machine that tells you if your pigs are joyous or your cows are grumpy… you’re spot on.

Up front: There’s little evidence to believe that so-called ’emotion recognition’ systems actually work. In the sense that humans and other creatures can often accurately recognize (as in: guess) other people’s emotions, an AI can be trained on a human-labeled data set to recognize emotion with similar accuracy to humans.

However, there’s no ground-truth when it comes to human emotion. Everyone experiences and interprets emotions differently and how we express emotion on our faces can vary wildly based on cultural and unique biological features.

In short: The same ‘science‘ driving systems that claim to be able to tell if someone is gay through facial recognition or if a person is likely to be aggressive, is behind emotion recognition for people and farm animals.

Google parent Alphabet has been working on “a moonshot” for the electric grid, with a secret project in its X R&D division aiming to figure out how to make power use more stable, and more green, than it is today. The research, revealed at the White House Leaders Summit on Climate, has been underway for the past three years. 

The team at X – which began as Google X, and then was spun out into a separate division when Google created Alphabet as its overarching parent – isn’t planning to put up power lines and install solar panels and wind turbines itself. Instead, it’s looking at whether a more holistic understanding of the grid would help in the transition to environmentally stable sources. 

“Right now our work is more questions than answers,” Astro Teller, Captain of Moonshots at X, says, “but the central hypothesis we’ve been exploring is whether creating a single virtualized view of the grid – which doesn’t exist today – could make the grid easier to visualize, plan, build and operate with all kinds of clean energy.”

Teller’s use of “moonshot” is a reference to the original NASA plan to put astronauts on the Moon, a project which was generally acknowledged as being ambitious and ground-breaking, not to mention with no immediate path to making a profit. While Teller leads the division, Alphabet brought in Audrey Zibelman – former CEO of Australian energy operator AEMO, and an expert in decarbonization of the electrical system – to lead this particular moonshot.

Building a computer that can support artificial intelligence at the scale and complexity of the human brain will be a colossal engineering effort. Now researchers at the National Institute of Standards and Technology have outlined how they think we’ll get there.

How, when, and whether we’ll ever create machines that can match our cognitive capabilities is a topic of heated debate among both computer scientists and philosophers. One of the most contentious questions is the extent to which the solution needs to mirror our best example of intelligence so far: the human brain.

Rapid advances in AI powered by deep neural networks—which despite their name operate very differently than thebrain—have convinced many that we may be able to achieve “artificial general intelligence” without mimicking the brain’s hardware or software.

Cerebras Systems has unveiled its new Wafer Scale Engine 2 processor with a record-setting 2.6 trillion transistors and 850,000 AI-optimized cores. It’s built for supercomputing tasks, and it’s the second time since 2019 that Los Altos, California-based Cerebras has unveiled a chip that is basically an entire wafer.

Chipmakers normally slice a wafer from a 12-inch-diameter ingot of silicon to process in a chip factory. Once processed, the wafer is sliced into hundreds of separate chips that can be used in electronic hardware.

But Cerebras, started by SeaMicro founder Andrew Feldman, takes that wafer and makes a single, massive chip out of it. Each piece of the chip, dubbed a core, is interconnected in a sophisticated way to other cores. The interconnections are designed to keep all the cores functioning at high speeds so the transistors can work together as one.

Findings debunk dozens of prominent published papers claiming to read minds with EEG.

By PURDUE UNIVERSITY 

Is it possible to read a person’s mind by analyzing the electric signals from the brain? The answer may be much more complex than most people think.

Purdue University researchers – working at the intersection of artificial intelligence and neuroscience – say a prominent dataset used to try to answer this question is confounded, and therefore many eye-popping findings that were based on this dataset and received high-profile recognition are false after all.

The Purdue team performed extensive tests over more than one year on the dataset, which looked at the brain activity of individuals taking part in a study where they looked at a series of images. Each individual wore a cap with dozens of electrodes while they viewed the images.

The Purdue team’s work is published in IEEE Transactions on Pattern Analysis and Machine Intelligence. The team received funding from the National Science Foundation.

Natural language processing rivals humans’ skills.

I did not write this article. 

In fact, it wasn’t written by any person. Every sentence you see after this introduction is the work of OpenAI’s GPT-3, a powerful language-prediction model capable of composing sequences of coherent text. The only thing I did was provide it with topics to write about. I did not even fix its grammar or spelling.

According to OpenAI, more than 300 applications are using GPT-3, which is part of a field called natural language processing. An average of 4.5 billion words are written per day. Some say the quality of GPT-3’s text is as good as that written by humans.

What follows is GPT-3’s response to topics in general investing.
