Final answer:
The incorrect statement about machine learning is that it requires explicit programming. Machine learning algorithms learn from data and do not need frequent human intervention to improve once they are developed.
Step-by-step explanation:
The statement about machine learning that is not true is: a) It requires explicit programming. While traditional software development relies on explicit programming, machine learning involves creating algorithms that learn from and make predictions on data. This process is semi-autonomous and does not require frequent human intervention once the learning algorithm is developed and trained.
Machine learning does indeed involve algorithms that improve automatically (option b), it is a subset of artificial intelligence (option c), and it heavily relies on data patterns to make predictions or decisions (making option d false).
