What are the three types of recall?
There are three main types of recall: free recall, cued recall and serial recall. Psychologists test these forms of recall as a way to study the memory processes of humans and animals. Two main theories of the process of recall are the two-stage theory and the theory of encoding specificity.

Is high or low recall better?
The higher the recall, the better. You can achieve a perfect recall of 1.0 when the model can find all instances of the target class in the dataset. Recall can also be called sensitivity or true positive rate. The term "sensitivity" is more commonly used in medical and biological research rather than machine learning.

What is associative recall?
Associative memories are models that store and recall patterns. Pattern recall (associative recall) is a process whereby an associative memory, upon receiving a potentially corrupted memory query, retrieves the associated value from memory.
What is type 2 failure?
