KI absichern bei PyBooks

Du bist dafür verantwortlich, bei PyBooks einen neuen Chatbot zu implementieren, der Nutzer:innen auf der Plattform unterstützt. Allerdings wurdest du auf mögliche adversariale Angriffe gegen textbasierte KI-Systeme aufmerksam gemacht. Damit der Chatbot gegenüber solchen Bedrohungen robust bleibt, recherchierst du verschiedene Strategien und Techniken.

Welche der folgenden Vorgehensweisen wäre am WENIGSTEN wirksam, um den Chatbot vor adversarialen Angriffen zu schützen?
