 Passage 3:Most Deep Learning systems rely on training and verification data that is generated and/or annotated by humans. It has been argued in media philosophy that not only low-payed clickwork (e.g. on Amazon Mechanical Turk) is regularly deployed for this purpose, but also implicit forms of human microwork that are often not recognized as such. The philosopher Rainer Mühlhoff distinguishes five types of "machinic capture" of human microwork to generate training data: (1) gamification (the embedding of annotation or computation tasks in the flow of a game), (2) "trapping and tracking" (e.g. CAPTCHAs for image recognition or click-tracking on Google search results pages), (3) exploitation of social motivations (e.g. tagging faces on Facebook to obtain labeled facial images), (4) information mining (e.g. by leveraging quantified-self devices such as activity trackers) and (5) clickwork. Mühlhoff argues that in most commercial end-user applications of Deep Learning such as Facebook's face recognition system, the need for training data does not stop once an ANN is trained. Rather, there is a continued demand for human-generated verification data to constantly calibrate and update the ANN. For this purpose Facebook introduced the feature that once a user is automatically recognized in an image, they receive a notification. They can choose whether of not they like to be publicly labeled on the image, or tell Facebook that it is not them in the picture. This user interface is a mechanism to generate "a constant stream of  verification data" to further train the network in real-time. As Mühlhoff argues, involvement of human users to generate training and verification data is so typical for most commercial end-user applications of Deep Learning that such systems may be referred to as "human-aided artificial intelligence".

Input: Consider Input: Question: Who was the Han emperor when the Xianbei killed the Xiongnu chanyu Youliu? Passage 1:In 2010, in collaboration with the actor Enrico Lo Verso and the musician Gabriele Denaro, he created the work Sensibilità Sonore, dedicated to topics such as marginalization, poverty and childhood. The following year, he produced the documentary "Il rimorso" (the remorse), a video that narrates violence against the women. The project was being projected every year during national conferences in various Italian cities and received an award for the Social Communication. The journal Fatto Quotidiano considered it as "a virtuous example that denounces the wrong". It was previewed at the Camera dei deputati della regione Lazio (Chamber of Deputies of the Region of Lazio) and introduced the conference "Lui per Lei - un ponte fra Napoli e New York" at the city Partenopea and at the municipality of Fiumincino by the iniziative of the Assesorato alle politiche sociali (Department of social policies) as well as the event "Io non ci sto più" (I am non there anymore) dedicated to the memory Eligia Ardita, a victim of a femicide act. 2013 he directed the documentary "Streghe a Pachino: Un caso giornalistico irrisolto" (Witches at Pachino: An unsolved journalistic case), recovering after 50 years, a mysterious fact initially narrated by Beppe Ferrara in 1963 that burst a war between the media, the politics and the omertà. The same year he films three special documentaries about Mario Sesti, Sergio Donati and the musician Mauro Di Domenico. He carried out interviews with personalities from the show business, created web projects, such as the ObamaStay, a project that promotes and supports the election of the American president, which received the appreciation from the Woman for Obama and from the Electionpaper, concerning the Italian elections reported by the press agencies Agi and RAI. wrote for the Sindacato Nazionale di Critica (National Syndicate of Italian Film Critics).

From 2014 he is devoted actively for the promotion of the Patrimonio Verghiano, redeveloping the historical Cunziria, the original film location of the famous Cavalleria Rusticana, directed by Franco Zeffirelli and inspiration scenery of the homonymous novel of the writer Giovanni Verga. Muscoso eventually turned the ancient village into a stage denominating it Teatro Cunziria".
 Passage 2:The Xianbei (; ) were an ancient nomadic people that once resided in the eastern Eurasian steppes in what is today Mongolia, Inner Mongolia, and Northeastern China. They originated from the Donghu people who splintered into the Wuhuan and Xianbei when they were defeated by the Xiongnu at the end of the 3rd century BC. The Xianbei were largely subordinate to larger nomadic powers and the Han dynasty until they gained prominence in 87 AD by killing the Xiongnu chanyu Youliu. However unlike the Xiongnu, the Xianbei political structure lacked the organization to pose a concerted challenge to the Chinese for most of their time as a nomadic people. After suffering several defeats by the end of the Three Kingdoms period, the Xianbei migrated south and settled in close proximity to Chinese society and submitted as vassals, being granted the titles of Dukes. As the Xianbei Murong, Tuoba and Duan tribes were one of the Five Barbarians who were vassals of the Han Chinese Western Jin and Eastern Jin dynasties, they took part in the Uprising of the Five Barbarians as allies of the Han Chinese Eastern Jin against the other four barbarians, the Xiongnu, Jie, Di and Qiang. The Xianbei were at one point all defeated and conquered by the Di Former Qin empire before it fell apart at the Battle of Fei River at the hands of the Eastern Jin. The Xianbei later founded their own states and reunited northern China as the Northern Wei. These states opposed and promoted sinicization at one point or another but trended towards the latter and had merged with the general Chinese population by the Tang dynasty.
 Passage 3:For the rest of the 1970s, Schneider opted to star in small-budgeted, independent European productions, such as the little-seen Swiss period piece Violanta (1976, with a young Gérard Depardieu), and three consciously feministic works: the Italian production I Belong to Me (Io Sono Mia) (1978, with Stefania Sandrelli); the graphic, disturbing Memoirs of a French Whore (French title: La Dérobade) (1978, alongside Miou-Miou, and for which Schneider was nominated for Best Supporting Actress at the 1980 5th César Awards); and the lesbian Dutch drama A Woman Like Eve, directed by Nouchka van Brakel, where Schneider plays the bohemian love interest of conflicted Monique van de Ven who is married to and has children with Peter Faber.

Input: Consider Input: Question: How long did the Austro-Prussian War last? Passage 1:She was born in the Kaʻū district of the Island of Hawaiʻi, to Mary Paʻahana Kanakaʻole (a native Hawaiian woman) and Henry Nathaniel Wiggin (originally from Massachusetts). In the traditional custom of hānai, she was initially reared by her mother's parents. Her grandmother Naliipoʻaimoku, a traditional dancer in the court of Queen Emma, taught her chants and stories, while her grandfather Keli'ikanaka'ole-o-Haililani (k) was a healer and kahuna pale keiki (obstetrician) who used lomilomi massage, laʻau lapaʻau (herbal medicine), hoʻoponopono (forgiveness), and pule (prayer). Her great grandmother Keliʻipaʻahana was a kahuna pule (priestess) in the Pele line. Keli'iPa'ahana's parents were the High Chief KU or Kauhi and High Chiefess Na'ai Hunali'i (The Hidden chief). Keli'iPa'ahana was interned in Halema'uma'u in 1869 in the Ka'u district. She married the High Chief Keli'iKanaka'ole (k) the son High Chief Kaelele and Princess Kekelaokalani. Family is known to inherit the sacred Ali'i Moe Kapu (the prostrating Taboo). Upon the death of her grandmother Nali'i Poai moku she returned to live with her parents and spoke both Hawaiian and English.
 Passage 2:The last meetings had revealed the rising antagonism with Britain and France, especially on Italian unification, the right to self-determination and the Eastern Question. The Alliance is conventionally taken to have become defunct with Alexander's death in 1825. France ultimately went her separate way after the July Revolution of 1830, leaving the core of Russia, Austria and Prussia as Central-Eastern European block which once again congregated to suppress the Revolutions of 1848. The Austro-Russian alliance finally broke up in the Crimean War: though Russia had helped to completely destroy the Hungarian Revolution of 1848, Austria did not take any action to support her ally, declared herself neutral and even occupied the Wallachian and Moldavian lands on the Danube upon the Russian retreat in 1854. Thereafter, Austria remained isolated, which added to the loss of her leading role in the German lands, culminating in the defeat of the Austro-Prussian War in 1866.
 Passage 3:Herschel was born in Slough, Buckinghamshire, the son of Mary Baldwin and William Herschel. He was the nephew of astronomer Caroline Herschel. He studied shortly at Eton College and St John's College, Cambridge, graduating as Senior Wrangler in 1813. It was during his time as an undergraduate that he became friends with the mathematicians Charles Babbage and George Peacock. He left Cambridge in 1816 and started working with his father. He took up astronomy in 1816, building a reflecting telescope with a mirror in diameter, and with a focal length. Between 1821 and 1823 he re-examined, with James South, the double stars catalogued by his father. He was one of the founders of the Royal Astronomical Society in 1820. For his work with his father, he was presented with the Gold Medal of the Royal Astronomical Society in 1826 (which he won again in 1836), and with the Lalande Medal of the French Academy of Sciences in 1825, while in 1821 the Royal Society bestowed upon him the Copley Medal for his mathematical contributions to their Transactions. Herschel was made a Knight of the Royal Guelphic Order in 1831.
