Generating Novel Content without Dataset

Posted by in category: robotics/AI

Rewriting the rules in GAN: Copy & paste features contextually.

GAN architecture has been the standard for generating content through AI, but can it actually invent new content outside what’s available in the training dataset? Or it’s just imitating the training data and mixing the features in new ways?

Using deep learning to control the unconsciousness level of patients in an anesthetic state

Posted by in categories: biotech/medical, health, information science, robotics/AI

In recent years, researchers have been developing machine learning algorithms for an increasingly wide range of purposes. This includes algorithms that can be applied in healthcare settings, for instance helping clinicians to diagnose specific diseases or neuropsychiatric disorders or monitor the health of patients over time.

Researchers at Massachusetts Institute of Technology (MIT) and Massachusetts General Hospital have recently carried out a study investigating the possibility of using learning to control the levels of unconsciousness of patients who require anesthesia for a medical procedure. Their paper, set to be published in the proceedings of the 2020 International Conference on Artificial Intelligence in Medicine, was voted the best paper presented at the conference.

“Our lab has made significant progress in understanding how anesthetic medications affect and now has a multidisciplinary team studying how to accurately determine anesthetic doses from neural recordings,” Gabriel Schamberg, one of the researchers who carried out the study, told TechXplore. “In our recent study, we trained a using the cross-entropy method, by repeatedly letting it run on simulated patients and encouraging actions that led to good outcomes.”

Neuroscience research shows we reorganize our memory based on how we will use it later

Posted by in categories: computing, neuroscience

A recent international scientific study published in the journal PLOS ONE has shown that the way the brain stores temporary information is different depending on the use one might give to that information in the future.

The research analysed the brain activity of 14 participants through functional magnetic resonance imaging while they were performing simple visual memory tasks on a computer screen. Differences in their brain activity patterns were found between participants who had to answer by communicating verbally or by pressing a button.

The memory that is under study is designated “working memory” and is used at all times. It is the type of memory that allows us to memorise a phone number or a license plate and use that information after (or not). This information is used and processed and, if it proves to be important, stored in the long-term memory.

Astronauts that will launch on SpaceX’s third crewed flight are actively training to ride Dragon

Posted by in categories: biotech/medical, entertainment, space travel

ESA Astronaut Pesquet revealed Crew-2 has been actively training for “Mission Alpha” aboard Crew Dragon. He shared photographs via Twitter of him training on SpaceX’s Crew Dragon simulator which involves learning how to control the spacecraft’s functions via a trio of touchscreen displays. – “Here’s the posse together, training on @SpaceX crew dragon. @Aki_Hoshide looking like a boss, and all of us wishing we had as cool socks as our awesome pilot @Astro_Megan. #MissionAlpha,” he wrote. During training, all astronauts are wearing face masks to protect each other from the coronavirus respiratory illness, pictured below.

To familiarize with the spacecraft, the astronauts train with an interactive simulator and touchscreen interface that is a replica of Dragon’s cockpit. Earlier this year, SpaceX released an online game that allows players to try to dock the Crew Dragon spacecraft to the Space Station, using similar controls the astronauts will use during their voyage in space. You can play the online game on SpaceX’s website: Crew Dragon Simulator.

Researchers develop ‘Trojan horse’ approach to destroy cancer cells

Posted by in categories: biotech/medical, nanotechnology

Researchers took a silica nanoparticle designated as ‘Generally Recognized As Safe’ by the US Food and Drug Administration and coated it with L-phenylalanine, and found that in lab tests with mice it killed cancer cells effectively and very specifically, by causing them to self-destruct.

Cancer cells are killed in lab experiments and tumor growth reduced in mice, using a new approach that turns a nanoparticle into a ‘Trojan horse’ that causes cancer cells to self-destruct, a research team at the Nanyang Technological University, Singapore (NTU Singapore) has found.

The researchers created their ‘Trojan horse’ nanoparticle by coating it with a specific amino acid — L-phenylalanine — that cancer cells rely on, along with other similar amino acids, to survive and grow. L-phenylalanine is known as an ‘essential’ amino acid as it cannot be made by the body and must be absorbed from food, typically from meat and dairy products.

These weird, unsettling photos show that AI is getting smarter

Posted by in category: robotics/AI

Of all the AI models in the world, OpenAI’s GPT-3 has most captured the public’s imagination. It can spew poems, short stories, and songs with little prompting, and has been demonstrated to fool people into thinking its outputs were written by a human. But its eloquence is more of a parlor trick, not to be confused with realintelligence.

Nonetheless, researchers believe that the techniques used to create GPT-3 could contain the secret to more advanced AI. GPT-3 trained on an enormous amount of text data. What if the same methods were trained on both text and images?

Now new research from the Allen Institute for Artificial Intelligence, AI2, has taken this idea to the next level. The researchers have developed a new text-and-image model, otherwise known as a visual-language model, that can generate images given a caption. The images look unsettling and freakish—nothing like the hyperrealistic deepfakes generated by GANs —but they might demonstrate a promising new direction for achieving more generalizable intelligence, and perhaps smarter robots as well.

US7379286B2 — Quantum vacuum energy extraction

Posted by in categories: particle physics, quantum physics, sustainability

A system is disclosed for converting part of theergy of the electromagnetic quantum vacuum available at any point in the universe to usableergy in the form of heat, electricity, mechanicalergy or other forms of power. This is accomplished using an effect on the electron configurations of atoms predicted by the theory of stochastic electrodynamics (SED). Within the context of SED theory it is predicted that the electronergy levels in atoms are determined by a balance of Larmor radiation vs. absorption of radiativeergy from the electromagnetic quantum vacuum. By suppressing electromagnetic quantum vacuumergy at appropriate a change may be effected in the electronergy levels which will result in the emission or release ofergy. This change inergies is analogous to a standard emission of a photon as an electron makes a transition from an excited to a lowerergy state, but on a longer time scale and with the change being a continuous one rather than a “jump” from oneergy level to another. Mode suppression of electromagnetic quantum vacuum radiation is known to take place in Casimir cavities. A Casimir cavity refers to any region in which electromagnetic modes are suppressed or restricted. When atomster into suitable micro Casimir cavities a decrease in the orbitalergies of electrons in atoms will thus occur, with the effect being most pronounced for outer shell electrons. Suchergy will be captured in the claimed devices. Upon form such micro Casimir cavities the atoms will be by the electromagnetic quantum vacuum. In this wayergy is extracted locally and globally from and by the electromagnetic quantum vacuum. This process may be repeated an unlimited number of times. This process is also with the conservation ofergy in that all usableergy does come at the of theergy of the electromagnetic quantum vacuum. Two example variations of a system are disclosed that permit multiple extractions of electromagnetic quantum vacuumergy during passage of a gas through a series of micro Casimir cavities and that operate in a self-sustaining, recycling fashion. Similar effects may be produced by acting upon molecular bonds. The disclosed devices are scalable in size andergy output for applications ranging from for small batteries to power plant sized of electricity. Since the electromagnetic quantum vacuum is thought to permeate thetire Universe, devices drawing power from the electromagnetic quantum vacuum in the fashion claimed will be effectively inexhaustible sources of power.
