 Competitie: MNIST - Competitie website Research & Development 2, 2012

Competitie: MNIST

Deze competitie telt niet mee voor het eindcijfer, maar is alleen bedoeld om het inzenden te testen. Ook kan je deze dataset gebruiken bij het schrijven van het verslag.

Het doel van de MNIST dataset is het herkennen van hadgeschreven cijfers. Elke instantie is een 'plaatje' van 14*14 pixels. De 14 regels zijn achter elkaar geplakt. De 196 features die je op die manier krijgt geven de grijswaarde van elk van de pixels. Er zijn 10 klassen, voor de cijfers 0 t/m 9.

Hier is een voorbeeld van een instantie uit de trainingsset, weergegeven als plaatje. Het programma waarmee je de instanties weer kan geven staat op blackboard.
