Redes neuronais e UC?

Citando:
"Para se perceber melhor a diferença, os cientistas recorrem a uma analogia. «O que a maioria faz é afinar um Bugatti Veyron, um automóvel que, como sabemos, já é bastante rápido, de forma a conseguir boas performances; o que nós fazemos é dar ao algoritmo um conjunto de peças (jantes, pneus, peças para o motor, travões, etc.) e deixar que o algoritmo entenda o contexto da situação, isto é, descubra como combinar aquelas peças de forma a construir um veículo que obtenha uma performance competitiva. Mas nem sequer o informamos que tem de ser um carro», ilustram."

Citando:
"The report states: “Over 1993-2014, the resulting globally averaged geocentric sea level change is eight per cent smaller than the barystatic contribution. Over the altimetry domain, the difference is about five per cent, and due to this effect, barystatic sea level rise will be underestimated by more than 0.1mm/yr over 1993-2014.”

According to the research, previous estimates of sea level rising in the Arctic Ocean have been inaccurate by a millimetre each year. 

The discrepancy happened because there is such a huge difference between geocentric sea level and barystatic sea levels. 

Geocentric sea levels are sea level as measured from the centre of the Earth and barystatic sea level is the mass of water in the sea. "

Citando:

"While flying by commercial passenger jet was fatality-free globally, the industry did suffer minimal losses. By one count, from the Aviation Safety Network, there were ten accidents involving commercial passenger or cargo airplanes, claiming 44 lives in 2017. (That organization focuses on crashes involving commercial planes, cargo or passenger, meant to carry 14 or more people; it didn’t include the 35 lives lost on the ground during a cargo plane accident in Kyrgyzstan.) By another count, from a Dutch firm called To70, 14 people were killed in aviation accidents in 2017. They focused just on commercial passenger planes heavier than 12,566 pounds at takeoff.

And it’s been a record-breaking 400-plus days since the last commercial passenger jet crash anywhere in the world, according to the Aviation Safety Network’s CEO, Harro Ranter."

Porque a distância não é tão preponderante como a inclinação com que chegam os raios solares à atmosfera:
