Self-driving cars are 25% better at predicting an idiot driver's move

By: Jak Connor | Artificial Intelligence | Posted: 1 day, 1 hour ago

One of the main problems with self-driving cars is that artificial intelligence inside the vehicle assumes all humans drive and act in the same way. This just simply isn't the case.

Luckily, researchers from MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) have taken that issue and begun examining it for potential solutions. Through their examination of this issue, they began predicting the behavior of other drivers on the road using social psychology techniques. They then fed these techniques to the artificial intelligence to help classify drivers into two basic categories "collaborative or competitive".

Through these classification techniques, the system was able to predict drivers' movements better when it came to lane mergers, faster turning, and more. The paper says that after these techniques were implemented, the artificial intelligence's accuracy increased by 25%. Wilko Schwarting, the lead author on the new paper, said, "Working with and around humans means figuring out their intentions to better understand their behavior. People's tendencies to be collaborative or competitive often spills over into how they behave as drivers."

Microsoft and SRL Diagnotics have developed an AI tool that can assist doctors in detecting cervical cancer in patients. This was done by letting the AI process "thousands" of annotated cervical smear images as examples. Once this was completed the AI was able to detect abnormalities within the images, this speeds up the diagnosing process for doctors who have an abdundant of patients that need testing.

At the moment the AI isn't live in the field as of yet, but it is ready for an "internal preview" at SRL. TechCrunch noted that in India roughly 67,000 women die due to cervical cancer each year. This number exceeds the amount of doctors that can process pap smears. So just imagine the time impact this AI would have on doctors, and how much they will be able to help more people that they just couldn't before, ultimately saving more lives in the long run.

'Superhuman' AI beats pro players & hits Grandmaster Starcraft II rank

By: Jak Connor | Artificial Intelligence | Posted: Nov 1, 2019 @ 4:13 CDT

An artificial intelligence developed by Google's AI firm DeepMind has managed to achieve the highest level of ranking in Starcraft II.

According to the results which were published in Nature, DeepMind's AI was released onto the European Starcraft II servers and placed within the top 0.15% of the regions 90,000 players. Jon Dodge, an AI researcher at Oregon State University in Corvallis was shocked at the progress the AI made, saying "I did not expect AI to essentially be superhuman in this domain so quickly, maybe not for another couple of years."

The AI is called AlphaStar and before it was released onto the European servers its speed was reduced to make a fairer contests. The researchers wanted players to also not know they were versing an AI, David Silver, who co-leads the AlphaStar project said "We wanted this to be like a blind experiment. We really wanted to play under those conditions and really get a sense of, 'how well does this pool of humans perform against us?'"

Deep neural network achieves human-like character movement & motion

By: Jak Connor | Artificial Intelligence | Posted: Oct 30, 2019 @ 1:08 CDT

Researchers have showcased a brand new 3D animated character being brought to life, the catch? It moves exactly like humans do.

Computer scientists from the University of Edinburgh and Adobe Research have developed a data driven technique that uses a deep neural network to accurately guide 3D animated characters. The precision of the neural network showcases characters in a variety of different motions such as sitting in chairs, picking up objects, running, side-stepping, climbing through obstacles and more.

Komura, coauthor and chair of computer graphics at the University of Edinburgh spoke out about the achievement, saying "The technique essentially mimics how a human intuitively moves through a scene or environment and how it interacts with objects, realistically and precisely." If you are interested in checking out the video of the animated character for yourself, click this link right here.

Facebook's new AI system can 'de-identify' peoples faces in real-time

By: Jak Connor | Artificial Intelligence | Posted: Oct 27, 2019 @ 1:03 CDT

Facebook researchers have announced the development of a new AI system that will assist in de-identifying peoples faces.

facebooks-new-ai-system-de-identify-peoples-faces-real-time_01

While you would originally think that Facebook would be working on an facial recognition software that is designed to identify peoples faces, that's exactly the opposite of what they doing. A new announcement out of Facebook Research shines a light on a new AI system that is designed to ever so slightly distort peoples faces.

Above you can see an example of Jennifer Lawrence's face being distorted. From the image, you can see what the AI generated isn't that different when compared to the original, but is different enough that facial recognition technology would have a much harder time identifying its her. This new technology is designed to assist people in keeping their identification secure from third-party facial recognition software that could potentially scam users.

This AI can spot brain hemorrhages with INSANE pixel-level accuracy

By: Jak Connor | Artificial Intelligence | Posted: Oct 24, 2019 @ 5:30 CDT

Since their discovery, brain hemorrhages have always been a doctors nightmare as missing even the tiniest hemorrhage can leave the patient in a fatal state. Now the responsibility might not all be on the doctors, AI has now been developed to shoulder some as well.

ai-spot-brain-hemorrhages-insane-pixel-level-accuracy_02

UC Berkeley and UCSF researchers have managed to conceive an algorithm that is able to detect brain hemorrhages with better accuracy than two out of four radiologists. This algorithm was created using massive amounts of data, 4,396 CT scans and convolutional neural network. While that sample size of CT scans might sound relatively on the smaller side, it should be noted that the AI was able to detect abnormalities within the scans "at the pixel level".

This means that the AI is able to decipher noise and other errors, that normal human doctors may run into, out of the equation. Therefore giving a more technical analysis on the brain scans which would then result in a more accurate assessment of what needs to be done. While you might think that is AI will be replacing doctors, it won't be. Instead, it will be assisting doctors in discovering abnormalities that they might of originally missed, essentially saving the doctors massive amounts of time.

Deep learning AI beats expert scholars at deciphering ancient texts

By: Jak Connor | Artificial Intelligence | Posted: Oct 21, 2019 @ 6:09 CDT

Researchers at the University of Oxford built and trained a neural network to be able to fill in the letter gaps of ancient texts, and now the AI is better than expert scholars.

The researchers tested the AI on ancient Greek inscriptions that were on objects such as stones, ceramics and metal. The texts are dated back to 1500 and 2600 years ago, and according to a report out of New Scientist, the AI creamed the humans in a head-to-head speed test at deciphering the artifacts. "In a head-to-head test, where the AI attempted to fill the gaps in 2949 damaged inscriptions, human experts made 30 percent more mistakes than the AI. Whereas the experts took 2 hours to get through 50 inscriptions, Pythia gave its guesses for the entire cohort in seconds."

New Scientist says that the AI which has been titled as Pythia was able to recognize and remember patterns in 35,000 different relics that amassed over 3 million words. It was also able to pick up patterns and include context such as the shape and layout within its descriptions. Pythia gives scholars predictions for missing letters or words within the text and rather than returning to the scholars with a single prediction Pythia gives multiple predictions and its level of confidence for each one.

OpenAI shows one-handed robot solve a Rubik's cube

By: Anthony Garreffa | Artificial Intelligence | Posted: Oct 15, 2019 @ 23:09 CDT

We all know our days are numbered, with our AI and robotic overlords planning to overthrow humanity at some point in the future... and it all seems like it'll begin with a Rubik's Cube.

AI research organization OpenAI have been hard at work building a general purpose, self-learning robot with its robotics division Dactyl unveiling its humanoid robotic hand in 2018 -- which is now being used to solve a Rubik's cube in less than 4 minutes flat. OpenAI is working on a number of different robotic parts with its in-house AI software, with this robotic arm just one of those.

Dactyl stumbles, but eventually solves the Rubik's cube -- with the team having a goal of seeing their AI-powered robotic appendages working on real-world tasks. Their robots packed with AI can learn real-world things, and won't need to be specifically programmed. This means that Dactyl is a self-learning robotic hand that looks at new tasks just like you and I would.

Bicycles, dinner tables & umbrellas could soon become pocket-sized

By: Jak Connor | Artificial Intelligence | Posted: Oct 15, 2019 @ 2:08 CDT

Have you ever wondered if it would be possible for you to pick up your bicycle, fold it into itself and then place it in your pocket? Well, this new super-compressible material could do just that.

Researchers at TU Delft have used artificial intelligence to create a new supercompressible but strong material. According to Miguel Bessa, assistant professor in materials science and engineering at TU Delft, the idea originiated when he was at the California Institute of Technology in the corner of the Space Structures Lab. Bessa noticed that a satellite structure could open long solar sails from an extremely small form-factor.

This observation drove Bessa's inspiration to create a supercompressible material that could be compressed into a fraction of its volume, but still remain strong. "If this was possible, everyday objects such as bicycles, dinner tables and umbrellas could be folded into your pocket." Bessa and his team used artificial intelligence instead of the traditional trial-and-error process to explore new design possibilities with metamaterials. This reduced experimentation to the absolute minimum, and after some time Bessa fabricated two designs that converted once brittle polymers into lightweight, recoverable and super-compressible metamaterials.

AI doesn't know why people with bigger hands have larger vocabularies

By: Jak Connor | Artificial Intelligence | Posted: Oct 14, 2019 @ 2:03 CDT

While it might seem like a silly idea at first, did you know that people with large hands actually have bigger vocabularies than people with small hands? Its true.

ai-know-people-bigger-hands-larger-volcabularies_01

Dr. Gary Marcus, the director of the NYU Infant Language Learning Center, and a professor of psychology at New York University has spoken out about this very topic and how artificial intelligence (AI) is also thrown into the mix. Marcus says this is an old joke that is tossed around by statisticians, and when a person takes into account the entire population and measure everyone's hand-size, the people with larger hands will have larger vocabularies. This is purely because of the fact that the people with larger hands tend to be older, and that adults tend to know more words then children.

This is correlated evidence, and not causation. Saying that something is causing people to learn new words, and causing them to grow their hands at the same time is an observed correlation between the two measured groups. Saying that growing your hand made your vocabulary grow is suggesting causation, this is a very important distinguishable definition that us humans can understand quite easily. Artificial intelligence on the other hand struggles to see the relationship between the two.
