Competitie: Eindcompetitie: Karakter herkenning - Competitie website Research & Development 2, 2012

Competitie: Eindcompetitie: Karakter herkenning

Bij de laatste competitie gaat het om het herkennen van karaketers uit scans van oud drukwerk. Elke instantie is een afbeelding van 20x20 pixels, dat zijn dus 400 features. Elke feature kan 0 zijn (papier) of 1 (inkt).

Er zijn 26 klassen, voor alle letters uit het alfabet. Er zijn verschillende lettertypes (normaal, cursief, Gotisch), en zowel hoofdletters als kleine letters.

Opmerking: een hoge accuracy betekent niet automatisch dat deze taak makkelijk is, want die laatste procenten maken in de praktijk het verschil tussen een volautomatisch systeem en een programma dat om de haverklap gecorrigeerd moet worden.

Het programma mnist-print op blackboard kan worden gebruikt om de instanties en prototypes te visuliseren.

Beoordeling: Minimum accuracy: 97%. 50% accuracy (boven het minimum), 50% reductie
