Module rust_bert::pipelines::summarization

Summarization pipeline

Abstractive summarization of texts based on the BART encoder-decoder architecture Include techniques such as beam search, top-k and nucleus sampling, temperature setting and repetition penalty. By default, the dependencies for this model will be downloaded for a BART model finetuned on CNN/DM. Customized BART models can be loaded by overwriting the resources in the configuration. The dependencies will be downloaded to the user's home directory, under ~/.cache/.rustbert/bart-cnn

from the University of Montreal and a separate report published Wednesday in Nature Astronomy by a team
from University College London (UCL), the presence of water vapour was confirmed in the atmosphere of K2-18b,
a planet circling a star in the constellation Leo. This is the first such discovery in a planet in its star's
habitable zone — not too hot and not too cold for liquid water to exist. The Montreal team, led by Björn Benneke,
used data from the NASA's Hubble telescope to assess changes in the light coming from K2-18b's star as the planet
passed between it and Earth. They found that certain wavelengths of light, which are usually absorbed by water,
weakened when the planet was in the way, indicating not only does K2-18b have an atmosphere, but the atmosphere
contains water in vapour form. The team from UCL then analyzed the Montreal team's data using their own software
and confirmed their conclusion. This was not the first time scientists have found signs of water on an exoplanet,
but previous discoveries were made on planets with high temperatures or other pronounced differences from Earth.
\"This is the first potentially habitable planet where the temperature is right and where we now know there is water,\"
said UCL astronomer Angelos Tsiaras. \"It's the best candidate for habitability right now.\" \"It's a good sign\",
said Ryan Cloutier of the Harvard–Smithsonian Center for Astrophysics, who was not one of either study's authors.
\"Overall,\" he continued, \"the presence of water in its atmosphere certainly improves the prospect of K2-18b being
a potentially habitable planet, but further observations will be required to say for sure. \"
K2-18b was first identified in 2015 by the Kepler space telescope. It is about 110 light-years from Earth and larger
but less dense. Its star, a red dwarf, is cooler than the Sun, but the planet's orbit is much closer, such that a year
on K2-18b lasts 33 Earth days. According to The Guardian, astronomers were optimistic that NASA's James Webb space
telescope — scheduled for launch in 2021 — and the European Space Agency's 2028 ARIEL program, could reveal more
about exoplanets like K2-18b."];
