The Challenge of Machine Learning in Space Weather Nowcasting and Forecasting
The numerous recent breakthroughs in machine learning (ML) make imperative to
carefully ponder how the scientific community can benefit from a technology
that, although not necessarily new, is today living its golden age. This Grand
Challenge review paper is focused on the present and future role of machine
learning in space weather. The purpose is twofold. On one hand, we will discuss
previous works that use ML for space weather forecasting, focusing in
particular on the few areas that have seen most activity: the forecasting of
geomagnetic indices, of relativistic electrons at geosynchronous orbits, of
solar flares occurrence, of coronal mass ejection propagation time, and of
solar wind speed. On the other hand, this paper serves as a gentle introduction
to the field of machine learning tailored to the space weather community and as
a pointer to a number of open challenges that we believe the community should
undertake in the next decade. The recurring themes throughout the review are
the need to shift our forecasting paradigm to a probabilistic approach focused
on the reliable assessment of uncertainties, and the combination of
physics-based and machine learning approaches, known as gray-box.Comment: under revie
Cyborg: From Science Fiction to Social Reality
The emerging technological developments across various scientific fields have brought about radical changes in the ways we perceive and define what it means to be human in today’s highly technologically oriented society. Advancements in robotics, AI research, molecular biology, genetic engineering, nanotechnology, medicine, etc., are mostly still in an experimental phase but it is likely that they will become a part of our daily experience. However, human enhancement and emergence of autonomous artificial beings have long been a part of futures imagined in SF and cyberpunk. While focusing on the phenomenon of cyborg as a product of both social reality and fiction, this paper will attempt to offer a new perspective on selected SF and cyberpunk narratives by treating them not only as fictions but as theories of the future as well
