Supervised and Unsupervised learning in machine learning

Machine learning is a subject of artificial intelligence, which means programming computers in terms of algorithm so that they can learn from data. Supervised learning and unsupervised learning are two types of Machine Learning systems. One can easily tell the difference between them by the criterion: whether or not they are trained with human supervision. Supervised learning and unsupervised learning are two extreme. The former completely depends on human supervision, while the latter doesn't n ...

AI: Deep Learning vs Machine Learning

Django use icontains with in for field lookup

In Django, __icontains and __in are field lookups to the QuerySet methods. __icontains is a case-insensitive containment test, and __in means that the field is in a given iterable. So I would like to do the following lookup:keywords = ['How', 'to', 'setup', 'PrismJS', 'and', 'Autoloader', 'plugin', 'with', 'Nuxt', '3?'] #Possible keywords of title Writings.objects.filter(title__icontains__in=arr)Unfortunately, we can not combine field lookups in Django. To implement our desire, we can use Q() ob ...
