## Deeper Explanation of Prolog Count

I hope this helps . The procedure it's recursive, but not tail recursive. Writing tail recursive procedures is an optimization that allows the system to transform recursion into iteration, avoiding useless stack usage for deterministics computations (like the one we are speaking of). In this case (that BTW it's the same of the builtin length/2, just with arguments swapped), we can use an accumulator, and rewrite the procedure in this way:
``````count(C, L) :- count(0, C, L).

count(Total, Total, []).
Count1 is SoFar + 1,
count(Count1, Count, Tail).
``````
``````    ...,
!, count(Count1, Count, Tail).
``````

## A deeper explanation of why Lazy Vals work in scala constructors?

Any of those help The object itself doesn't exist, but fields within the object can exist and be calculated.
What's happening is that from within A's constructor, it's accessing x1 and therefore forcing the lazy value to be computed. The reason A can know it needs to call B's x1 method, is because it's dynamically dispatched (just like in Java).
``````B.x1\$lzycompute
B.x1
A.<init>
B.<init>
``````
``````public class Testing {

public static void main(String[] args) {
new B();
}

public static abstract class A {

public abstract String x1();

public A() {
System.out.println(x1());
}
}

public static class B extends A {
private boolean inited = false;
private String x1;

private String computeX1() {
x1 = "hello";
inited = true;
return x1;
}

public String x1() {
return this.inited ? x1 : computeX1();
}
}

}

## Masked language model processing, deeper explanation

wish helps you If you don't use random replacement during training your network won't learn to extract useful features from non-masked tokens.
in other words, if you only use masking and try to predict them, it will be a waste of resources for your network to extract good features for the non-masked tokens(remember that your network is as good as your task and it will try to find the easiest way to solve your task)
