Google DeepMind Introduces Two Unique Machine Learning Models, Hawk And Griffin, Combining Gated Linear Recurrences With Local Attention For Efficient Language Models

Posted by in categories: employment, robotics/AI

Artificial Intelligence (AI) and Deep Learning, with a focus on Natural Language Processing (NLP), have seen substantial changes in the last few years. The area has advanced quickly in both theoretical development and practical applications, from the early days of Recurrent Neural Networks (RNNs) to the current dominance of Transformer models.

Models that are capable of processing and producing natural language with efficiency have advanced significantly as a result of research and development in the field of neural networks, particularly with regard to managing sequences. RNN’s innate ability to process sequential data makes them well-suited for tasks involving sequences, such as time-series data, text, and speech. Though RNNs are ideally suited for these kinds of jobs, there are still problems with scalability and training complexity, particularly with lengthy sequences.

This Machine Learning Paper Presents a General Data Generation Process for Non-Stationary Time Series Forecasting

Posted by in category: robotics/AI

One of the cornerstone challenges in machine learning, time series forecasting has made groundbreaking contributions to several domains. However, forecasting models can’t generalize the distribution shift that changes with time because time series data is inherently non-stationary. Based on the assumptions about the inter-instance and intra-instance temporal distribution shifts, two main types of techniques have been suggested to address this issue. Both stationary and nonstationary dependencies can be separated using these techniques. Existing approaches help reduce the impact of the shift in the temporal distribution. Still, they are overly prescriptive because, without known environmental labels, every sequence instance or segment might not be stable.

Before learning about the changes in the stationary and nonstationary states throughout time, there is a need to identify when the shift in the temporal distribution takes place. By assuming nonstationarity in observations, it is possible to theoretically identify the latent environments and stationary/nonstationary variables according to this understanding.

Scientists say cosmic dust may have kick-started life on Earth

Posted by in category: chemistry

“Enriched cosmic dust, on the other hand, I think makes for a plausible source.”

Dr. Walton’s team now plans to test their theory experimentally, using large reaction vessels to recreate the conditions that might have prevailed in the primeval melt holes, then setting the initial conditions to those that probably existed in a cryoconite hole four billion years ago before waiting to see whether any chemical reactions of the kind that produce biologically relevant molecules do indeed develop.

The post Scientists say cosmic dust may have kick-started life on Earth appeared first on Talker.

James Webb Space Telescope captures the end of planet formation

Posted by in category: alien life

The James Webb Space Telescope (JWST) is helping scientists uncover how planets form by advancing understanding of their birthplaces and the circumstellar disks surrounding young stars.

In a paper published in The Astronomical Journal, a team of scientists, led by Naman Bajaj of the University of Arizona and including Dr. Uma Gorti at the SETI Institute, images for the first time winds from an old planet-forming disk (still very young relative to the sun) which is actively dispersing its gas content. The disk has been imaged before, but winds from old disks haven’t. Our knowing when the gas disperses is important, as it constrains the time left for nascent planets to consume the gas from their surroundings.

At the heart of this discovery is the observation of TCha, a young star (relative to the sun) enveloped by an eroding disk notable for its vast dust gap, approximately 30 astronomical units in radius. For the first time, astronomers have imaged the dispersing gas (aka winds) using the four lines of the noble gases neon (Ne) and argon (Ar), one of which is the first detection in a planet-forming disk. The images of [Ne II] show that the wind is coming from an extended region of the disk.

The Fermi Paradox: Imprisoned Planets

Posted by in categories: alien life, existential risks

Getting into space is difficult, but it may be that other worlds have even harder times at it than we do, imprisoned by orbital debris, high gravity, or even being quarantined by alien civilizations.

The Fermi Paradox: Absent Megastructures

Posted by in categories: alien life, existential risks, robotics/AI

The great mystery of where all the aliens are in our vast Universe contemplates ancient interstellar civilizations building enormous megastructures that rival worlds or even stars in the immensity… and asks why we can’t see these giant alien artifacts.
