KW 37: AI researchers simulate the complexity of a biological neuron, New iRobot Roomba uses AI to avoid pet poop, AI completes Beethoven’s 10th Symphony


AI researchers simulate the complexity of a biological neuron: Neuroscientists are investigating how many artificial neurons are needed to simulate a single biological neuron. Artificial neural networks are the basic technology of almost all AI advances of the last decade. On average, about 1,000 artificial neurons correspond to a single biological neuron in a rat. Different neurons, such as those of humans, could require even more layers and artificial neurons, according to the researchers. The ultimate goal of the research is an AI system that mimics the functionality, ability and diversity of the brain.

New iRobot Roomba uses AI to avoid pet poop: Roomba supplier iRobot is introducing the Roomba j7+, a model that uses Artificial Intelligence to detect and avoid pet droppings. This is done via the hoover’s cameras and an underlying database that has been trained with images of animal excrement and thousands of faeces modelled with Play-Doh.

AI completes Beethoven’s 10th Symphony: World premiere on the TV channel Beethoven’s 10th Symphony is no longer unfinished. An artificial intelligence has completed the work on the basis of the fragments that already exist. Other symphonies by Beethoven and contemporary music by third parties have also been completed by the system.

How Facebook wants to change our memory culture with AI: Social media company Facebook is releasing a large 3D dataset to help turn videos into 3D experiences. This function of reconstructing 3D objects from photos and videos through artificial intelligence has great potential for the digital industry, for example for AR and VR applications or the rapid production of 3D models for games and films.

Dance videos with digitally duplicated dancers: At the world’s largest conference on computer graphics (Siggraph), a team of researchers from Shanghai showed how AI could soon be at work in real filmed scenes. The footage uses multiple cameras to record everything. The 16 cameras are synchronised and record in 4K resolution. Zooming in and out and shifting in time is done automatically by the volume rendering technology used. What doesn’t work, however, are different lighting conditions in different scenarios, which would then look unrealistic.

GPT-3 chatbot project: OpenAI pulls the plug: Indie developer Jason Rohrer experimented with OpenAI’s powerful text AI GPT-3 for the first time in 2020. The chatbot was supposed to act as human as possible and resemble the bot of the same name from the film „Her“. His experiment resulted in Project December, a website where visitors can chat with Samantha or create chatbots with their own personalities. But after the demand became too much, OpenAI imposed guidelines on the project that Rohrer didn’t want to implement. OpenAI therefore deleted the chatbot.

The US Innovation and Competition Act, passed by the US Senate in June, includes nearly $250 billion for new technologies, including AI.


AI enables earlier diagnosis of lung cancer: An artificial intelligence-based program detects signs of lung cancer on CT scans a year earlier than was previously possible, according to a study by the National Institute for Research in Digital Science and Technology (Inria) at the Université Côte d’Azur. The AI identified 172 of the 177 malignant tumors. It was 97% effective in detecting cancer. The five tumors detected by the program were located near the center of the chest. There, tumors are harder to distinguish from healthy areas of the body. Currently, however, the program still identifies too many false positive hits that are not cancer. According to research director Benoît Audelan, significant improvements still need to be made here before the system can be handed over to hospitals.

Bio-compatible AI platform implanted in humans: Scientists have developed a polymer-based fiber network that can be implanted in the human body. The arrangement of the fibers process data in a way analogous to the brain. The system can classify healthy and pathological patterns in biological signals such as heartbeats in real time and thus detect pathological changes without medical supervision. In the process, the polymer network consumed less energy than a pacemaker.


AI detects abuse in children’s drawings: A new Israeli software can detect evidence of abuse in children’s drawings. With a high degree of accuracy, it should soon also be able to detect bullying, loneliness and eating disorders. The researchers are working with psychologists who can find evidence of abuse in the pictures of their young patients themselves. In their self-portraits, sexual coercion is usually said to leave a clear trace. In order to better perceive these features, the research center, together with the company Amina, developed a system that, based on the characters entered, creates algorithms. The accuracy is currently 90%.


„AI has the potential to decisively advance the digital transformation of administration at all levels.“
State Secretary Dirk Schrödter, the head of the State Chancellery in the German state of Schleswig-Holstein, has awarded a grant of around 135,000 euros to the University in Lübeck for its research in AI.


AI transforms heroes into real people: In many cases, the portraits generated by AI are impressively close to their digital counterparts. The video game Dark Souls, from which the heroes in a new experiment are humanized, does not offer graphically high-quality character models. So the StyleCLIP system has to be more inventive in generating images to make the faces look human. StyleCLIP, on the other hand, does less well with monsters; a ghost baby suddenly turned into a wrapped-up middle-aged man with a moustache.
