Answer and Explanation:
Some of the advantages of using the F measure (weighted harmonic mean) over using the Precision & Recall when evaluating an IR system performance are as follows-
- Precision quantifies the number of positive class predictions that actually belong to the positive class.
- Recall quantifies the number of positive class predictions made out of all positive examples in the dataset.
- F-Measure provides a single score that balances both the concerns of precision and recall in one number.
- A measure that combines precision and recall is the harmonic mean of precision and recall, the traditional F-measure or balanced F-score:
F=2((precision.recall)/(precision+recall))

<span>A network layout or topology that is the most common, the most simple and easiest to use out of the four network topologies is the Bus topology, one cable is used for installation so it is also the cheapest network type.</span>
Answer:
public Clock(int hours) {
this.hours = hours;
}
Explanation:
In Java programming language, Constructors are special methods that are called to initialize the variables of a class when a new object of the class is created with the new keyword. Consider the complete code for the class below;
<em>public class Clock {</em>
<em> private int hours;</em>
<em> public Clock(int hours) {</em>
<em> this.hours = hours;</em>
<em> }</em>
<em>}</em>
In this example above, an object of this class can created with this statement Clock myclock = new Clock(6); This is a call to the constructor and passes a parameter (6) for hours
