Dat inspireerde me om een artikel te schrijven om het mysterie te ontrafelen. Dus hier is alles wat je moet weten over <a href=\"https:\/\/buyzero.de\/collections\/google-aiy-coral\/products\/google-coral-usb-accelerator\">de Google Koraal USB-accelerator<\/a>.<\/p>\n\n\n\n<p>De Coral USB Accelerator is primair ontworpen voor AI-toepassingen aan de rand met laag stroomverbruik. <\/p>\n\n\n\n<p>Het is geschikt voor taken zoals beeld- en videoanalyse, objectdetectie en spraakherkenning op apparaten zoals Raspberry Pi of laptops.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Overzicht<\/h2>\n\n\n\n<p>In het kort is de Google Coral USB Accelerator een processor die gebruik maakt van een Tensor Processing Unit (TPU), wat een ge\u00efntegreerd circuit is dat erg goed is in het doen van matrixvermenigvuldigingen en optellingen. <\/p>\n\n\n\n<p>Matrixvermenigvuldiging is het materiaal dat je nodig hebt om neurale netwerken te bouwen. <\/p>\n\n\n\n<p>En je zult zeker niet ver komen als je alleen neurale netwerken probeert te bouwen op je Raspberry Pi.<\/p>\n\n\n\n<p>Als zodanig voegt de versneller nog een processor toe die specifiek bedoeld is om de lineaire algebra te doen die nodig is voor machinaal leren.<\/p>\n\n\n\n<p>Zoals je waarschijnlijk wel weet, is het idee achter machine learning het ontwikkelen van modellen die patronen analyseren en leren uit een dataset. Deze dataset heeft verschillende inputs en overeenkomstige outputs. Eenmaal getraind kunnen deze modellen nieuwe inputs aannemen, de geleerde patronen synthetiseren en de juiste outputs of voorspellingen genereren.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/08\/coral-usb-accelerator-768x1024.png\" alt=\"Google Koraal USB-versneller\" class=\"wp-image-5087\" style=\"width:438px;height:584px\" width=\"438\" height=\"584\" srcset=\"https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/08\/coral-usb-accelerator-768x1024.png 768w, https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/08\/coral-usb-accelerator-225x300.png 225w, https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/08\/coral-usb-accelerator-9x12.png 9w, https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/08\/coral-usb-accelerator.png 960w\" sizes=\"auto, (max-width: 438px) 100vw, 438px\" \/><\/figure>\n<\/div>\n\n\n<p><\/p>\n\n\n\n<p>TPU's werken veel sneller en met veel minder energie dan CPU's voor machine learning, omdat ze geen andere programma's draaien en geen toegang hoeven te hebben tot gedeeld geheugen.<\/p>\n\n\n\n<p>De TPU op de Coral USB Accelerator gebruikt TensorFlow Lite, wat een aangepaste versie is voor kleinere apparaten.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">De Coral USB-accelerator gebruiken<\/h2>\n\n\n\n<p>Wat er vooral geweldig aan is, is hoe toegankelijk het AI-ontwikkeling maakt. <\/p>\n\n\n\n<p>Aan de slag gaan is een koud kunstje. <\/p>\n\n\n\n<p>Echt, alles wat je nodig hebt is een Google Coral USB Accelerator (uiteraard) en een computer met een vrije USB-poort en Python 3.5 of hoger.<\/p>\n\n\n\n<p>En het is het vermelden waard dat het werkt met Mac, Windows en Linux (specifiek Debian-gebaseerde besturingssystemen, zoals Ubuntu of het Raspberry Pi OS). Dus je kunt het zeker aan de praat krijgen.<\/p>\n\n\n\n<p>Wanneer je hem instelt, moet je beslissen of je hem op maximale klokfrequentie of op verlaagde klokfrequentie wilt laten draaien. De maximale klokfrequentie is uiteraard krachtiger, maar verbruikt ook meer stroom. En het kan ongelooflijk heet worden.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/09\/googlecoralback-1024x768.jpg\" alt=\"De achterkant van de Google Coral\" class=\"wp-image-5095\" style=\"width:532px;height:399px\" width=\"532\" height=\"399\" srcset=\"https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/09\/googlecoralback-1024x768.jpg 1024w, https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/09\/googlecoralback-300x225.jpg 300w, https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/09\/googlecoralback-768x576.jpg 768w, https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/09\/googlecoralback-16x12.jpg 16w, https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/09\/googlecoralback.jpg 1280w\" sizes=\"auto, (max-width: 532px) 100vw, 532px\" \/><\/figure>\n<\/div>\n\n\n<p><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Een beeldherkenningsmodel uitvoeren<\/h2>\n\n\n\n<p>Op de <a href=\"https:\/\/coral.ai\/docs\/accelerator\/get-started\/#1-install-the-edge-tpu-runtime\">Google Koraal website<\/a>Ze bieden een prachtige test om te laten zien hoe de Coral USB Accelerator werkt. In hun voorbeeld is het in staat om verschillende vogels te herkennen met een behoorlijk opmerkelijke nauwkeurigheid.<\/p>\n\n\n\n<p>Dit is dus hoe je het beeldherkenningsmodel op je Raspberry Pi draait.
