If you were inventing the farm today, why would you put it outside, on a giant plot of land? OK, there's the sunlight thing, but then you get droughts and frosts and plant-munching insects that have to be battled with harmful pesticides. And because outdoor farms need so much acreage, they're usually far from most of their customers -- which means that by the time a tomato gets to you in a city, it tastes like a baseball. But now, upstarts such as Bowery farming, AeroFarms, and Lettuce Networks are doing something different. They're using data and artificial intelligence to operate more efficiently than traditional farms.
Warning: spoilers ahead for Netflix's Lost in Space. In the first episode of Netflix's new Lost in Space, Will Robinson (Maxwell Jenkins) discovers a robot (Brian Steele) and saves it from a spreading forest fire. As a result, it seems to imprint upon him, following him around and obeying him like a loyal pet.
Space is a cold and barren place. Nothing can exist there, nothing!" Ludwig Von Drake, an obscure uncle of Donald Duck and a professor of astronomy, is sitting on a high stool in his observatory. When he sees that he is being filmed, he falls off and lands on the floor with a loud thump. "Now I can see stars I've never seen before!" he groans. He walks over to a table with a large pile of books on it. The thickest of them all is a guide to space travel that he wrote himself. In a 45 -minute- long monologue, he tells us in a thick German accent how mankind discovered the planets in our solar system and has fantasized about everything that might be crawling around on them. He tells us about Copernicus and Galileo, and about Kepler's dreams about Martians, Fontenelle's speculations about life on other planets, and even John Herschel's Great Moon Hoax. Science fiction comes to life in the colorful cartoon: Hairy space beings and flying saucers shoot across the screen. At the end, the professor has the last word. He finds all these fantasies poppycock; nothing can live in that empty, barren space! But, as he is speaking, Von Drake is kidnapped by a black Martian robot from one of his stories. The cartoon, Inside Outer Space, is part of Walt Disney's Wonderful World of Color, a television series from the 1960s. The absent minded duck professor hosts a number of episodes, each with their own topic: the history of flight, the color spectrum, space--all exciting stuff for American kids in the Space Age.
Proper name categories also posed some interesting challenges. It was straightforward to identify all cases in which proper name categories might be relevant based on whether the proper name in question was mentioned, which led to a high average recall score of 98 percent. However, average precision for these 539 categories was only 84 percent. The lower-precision scores occurred because Reuters only wanted proper name categories assigned to stories in which the person, place, organization, or exchange was the focus rather than just a mention. The 135 economic categories, however, tended to present greater problems for recall (average 89 percent) than for precision (average 92 percent) because of the typically large variety of phrases that could be used to express them.
