AI is getting better at generating porn

#artificialintelligence

A red-headed woman stands on the moon, her face obscured. Her naked body looks like it belongs on a poster you'd find on a hormonal teenager's bedroom wall -- that is, until you reach her torso, where three arms spit out of her shoulders. AI-powered systems like Stable Diffusion, which translate text prompts into pictures, have been used by brands and artists to create concept images, award-winning (albeit controversial) prints and full-blown marketing campaigns. But some users, intent on exploring the systems' murkier side, have been testing them for a different sort of use case: porn. AI porn is about as unsettling and imperfect as you'd expect (that red-head on the moon was likely not generated by someone with an extra arm fetish).

Altair Announces Digital Twin Solution

#artificialintelligence

TROY, MI, Oct 4, 2022 – Altair, a global leader in computational science and artificial intelligence (AI), announced the launch of its broad digital twin solution that features the market's most connected, cross-functional capabilities that can be deployed through any and every stage of a product lifecycle. "Altair offers the market's premier digital twin solution that can transform the way people and organizations design, develop, implement, and improve products and processes," said Sam Mahalingam, chief technology officer, Altair. "Moving forward, we will continue establishing our digital twin leadership to provide further democratized, more accessible digital twin solutions." Combining Altair's leading simulation, high-performance computing (HPC), AI, data analytics, and Internet of Things (IoT) capabilities, companies can apply digital twin technology at any stage of the product lifecycle -- from concept through in-service -- as part of a cross-functional, enterprise-wide effort that advances collaboration and eliminates departmental silos. Additionally, Altair's open, vendor-agnostic digital twin solution is the premier offering that gives customers the flexibility to run Altair software anywhere – whether on-site, in the cloud, hybrid, or via plug-and-play appliances – and the freedom to choose from a comprehensive toolset through a cost-effective, units-based licensing model called Altair Units.


Stretchy, Wearable Synaptic Transistor Turns Robotics Smarter

#artificialintelligence

Yu says that the artificial neurons in the device were designed to perform like neurons in the ventral tegmental area, which is a small segment of the human brain. Neurons first process and transmit information by releasing neurotransmitters at their synapses, which are usually located at the neural cell ends. Excitatory neurotransmitters then trigger the activity of other neurons and are associated with enhancing memories. On the other hand, inhibitory neurotransmitters reduce the activity of other neurons, meaning they are associated with weakening memories.


NLP: Stop Words, When and Why to Use Them - PythonAlgos

#artificialintelligence

There are 326 "Stop Words" by default in spaCy. What are stopwords (or stop words)? They're common words that we don't want to include in some of our analysis when we perform Natural Language Processing. These are words that generally don't contribute anything to the meaning of the text. However, we can't always remove stopwords.


Creating Portraits with Artbreeder

#artificialintelligence

Like many people who saw designer Daniel Voshart's Roman emperor portraits created in Artbreeder and Photoshop, I was impressed with the results. Using the neural-net tool Artbreeder, Photoshop and historical references, I have created photoreal portraits of Roman Emperors. For this project, I have transformed, or restored (cracks, noses, ears etc.) 800 images of busts to make the 54 emperors of The Principate (27 BC to 285 AD). Artbreeder uses a machine learning method called generative adversarial network (GAN) to manipulate images. Voshart tweaked images from Photoshop to Artbreeder and back again until he got what he wanted.


Climate simulation more realistic with artificial intelligence

#artificialintelligence

Accurately modeling extreme precipitation events remains a major challenge for climate models. These models predict how the earth's climate may change over the course of decades and even centuries. To improve them especially with regard to extreme events, researchers now use machine learning methods otherwise applied to image generation. Computers already use artificial intelligence to improve the resolution of fuzzy images, to create images imitating the style of particular painters based on photographs, or to render realistic portraits of people who do not actually exist. The underlying method is based on what are referred to as GANs (Generative Adversarial Networks).


Can hi-tech fish farming replace traditional agriculture?

#artificialintelligence

As the climate gradually grows warmer and cattle farming becomes less and less attractive a solution for world food production, scientists and innovators are working to develop suitable alternatives that can feed the world without wasting too many of its resources. While modern seafood farming -- or "aquaculture" -- is a step in the right direction, its current methods are problematic in their own right. If aquaculture's problems can be solved, though, it stands to revolutionize the way we feed the world. In search of this holy grail are some of Israel's brightest minds: aquaculture technology companies and innovators developing new, better ways to yield sustenance from the sea. Biologist Roni Hochman Sussman is the director of AquaculTech, a joint initiative of the Ministry of Economy and Industry Ministry, the Agriculture Ministry, the Israel Innovation Authority and the Israel Innovation Institute.


Deepfake audio has a tell

#artificialintelligence

An office worker answers it and hears his boss, in a panic, tell him that she forgot to transfer money to the new contractor before she left for the day and needs him to do it. She gives him the wire transfer information, and with the money transferred, the crisis has been averted. The worker sits back in his chair, takes a deep breath, and watches as his boss walks in the door. The voice on the other end of the call was not his boss. The voice he heard was that of an audio deepfake, a machine-generated audio sample designed to sound exactly like his boss.
