 👩‍🦰 Du hilfst Sigrún beim Bau eines Fischsortierapparats. Dafür hattest du die Längen (in cm) von 50 Hering und 50 Lodde vermessen und nebenstehendes Histogramm erstellt. Alles links vom Threshold (rote Linie) wird vom Apparat als Lodde angesehen, alles rechts davon als Hering. Gemäss nebenstehenden Histogramm arbeitet der Apparat mit einem Threshold zwischen 20 cm und 25 cm fehlerfrei.

 💡 Daher fragst du Sigrún noch einmal um 50 Hering und 50 Lodde an, welche sie dir prompt zukommen lässt.

   - Wie gut kann dein Fischsortierapparat jetzt Hering von Lodde unterscheiden? Prüfe mit dem roten Threshold, welches der kleinste Fehler ist, den du erreichen kannst. Trage das Resultat ins Textfeld ein. {{gem/match?0=N4IgTgpg5hAeAOIBcIB0AqALABgyANCAGYA2AhlAM7IgCWBIALnIzSAL5A#840f939eb679c2df}}
   - Worauf musst du bei der Auswahl der Beispiele bzw. Fische achten, wenn du verschiedene Dinge (hier Fische) mit Thesholds in Klassen unterteilen möchtest? Vergleiche dazu das obenstehende mit dem untenstehenden Histogramm. Halte deine Einsicht im Textfeld fest. Vergleiche danach deine Antwort mit der Musterlösung.{{gem/plain?0=N4XyA#0170bd536d248cf6}}++Musterlösung|\\ \\ Die Beispiele müssen alle Varianten aller Klassen beinhalten. Z.B. ein Fischsortierapparat, der nur für grosse Fische optimiert wird, wird bei kleinen Fischen versagen.++

   - In der linken Grafik hast du deine Linie um die Fische herum gezeichnet - die Fische in der linken Grafik nennen wir deshalb "Trainingsfische". In der rechten Grafik siehst du, wie gut deine Linie bezüglich den weiteren Fischen abschneidet - die Fische in der rechten Grafik nennen wir deshalb "Validationsfische". Halte im Textfeld fest, wie viele Trainingsfische und wie viele Validationsfische du mit deiner Linie falsch klassifizierst hast. {{gem/plain?0=N4XyA#ab24b6a53e67c5b3}}
