Clusters

For this use case, we will load the online shoppers’ intentions data set and go through the steps of preprocessing, clustering, evaluation and then determining the significantly associated features for the cluster labels. This data set contains in total of 12330 samples with 18 features. This mixed dataset requires a few more pre-processing steps to make sure that all variables have similar types or units of measurement. Thus, the first step is to create homogeneous data sets with units that are comparable. A common…

The standard model of cosmology is the prevailing scientific theory that explains the evolution and structure of the universe. It suggests that the universe began with the Big Bang, an intense explosion that occurred approximately 13.8 billion years ago. The Big Bang led to the formation of galaxies, stars, and planets, and the universe has been expanding ever since. The Standard Model also describes the universe as being composed of dark matter and dark energy, which make up about 95% of its total mass-energy content,…

The Snapdragon 8 Gen 2 brought a huge performance leap and better efficiency, but we now hear its successor has even higher ambitions. A noted tipster reveals the next generation of the flagship platform by Qualcomm will pack new CPU architecture, while pushing clock speeds significantly. The Snapdragon 8 Gen 3 is said to have one prime Cortex-X4 CPU core at unprecedented 3.7 GHz, five powerful cores for performance and two small cores for efficiency. According to Digital Chat Station the model number is SM8650, and…

To determine data-driven clusters, that may behold new or unknown information, we carefully need to perform four constitutive steps to go from the input data set to sensible clusters. Libraries such as distfit and clusteval can help in this process.Coming up with a sensible grouping of samples requires more than blindly running a clustering algorithm.Step 1: Investigate the underlying distribution of the data.Investigating the underlying distribution of the data is an important step because clustering algorithms rely on…

Since its launch, the James Webb Space Telescope has been astonishing the world with its capabilities despite being in service for less than two years. NASA's $10 billion space telescope has been capturing breathtaking images of far-off galaxies, star clusters, ancient black holes and other celestial objects. Now, it has added another feather to its cap by giving us a glimpse into the past of galaxies, when they wer babies, and how they formed, assembled and may look now.A recent study has shed light onto the early…

This image taken by NASA’s Hubble Space Telescope shows a spiral galaxy (bottom left) in front of a large galaxy cluster. New research leveraged an artificial tool to estimate the masses of galaxy clusters more accurately. Credit: ESA/Hubble & NASAAstronomers at the Institute for Advanced Study and the Flatiron Institute, along with their collaborators, have utilized artificial intelligence to improve the method of calculating the mass of massive clusters of galaxies. The AI revealed that by incorporating a simple…

Details about Qualcomm's next-gen flagship SoC have begun trickling in, months ahead of its expected debut. The upcoming Snapdragon 8 Gen 3 SoC is said to feature a restructured CPU cluster layout, and will most likely support only 64-bit computing, removing all 32-bit support. The chip is said to be codenamed either Lanai or Pineapple, and is expected to be launched in late 2023, possibly during Qualcomm's annual Summit in Hawaii. If the company's past launches are anything to go by, then we'll probably also see debut of…

Astronomers observing a mysterious radio halo from the galaxy cluster Abell 1213 have uncovered something unexpected. While the radio signals themselves remain puzzling, they have allowed researchers to unveil the core of the galaxy cluster, right down to the central galaxy contained within.  Even more intriguing about the discovery is that the researchers found evidence of mergers between the galaxies with the cluster. The off-center nature of the radio halo has also provided scientists with quite a puzzle, as…

The aim would be to create ecosystems that would bring together fabrication plants, research-and-development labs, final packaging facilities for assembly of chips and the suppliers needed to support each phase of the operation, Ms. Raimondo said Thursday. “Our vision at the end of this initiative is to make it so that the United States of America is the only country in the world where every company capable of producing leading edge chips will have a significant R&D and high-volume manufacturing presence in our…

NGC 346, shown here in this image from NASA’s James Webb Space Telescope Near-Infrared Camera (NIRCam), is a dynamic star cluster that lies within a nebula 200,000 light years away. Webb reveals the presence of many more building blocks than previously expected, not only for stars, but also planets, in the form of clouds packed with dust and hydrogen.Credit: Science: NASA, ESA, CSA, Olivia C.
