The correct answer is: C. Combining classifiers improves accuracy.
Combining classifiers is a technique that can be used to improve the accuracy of a classification model. The basic idea is to combine the predictions of multiple classifiers, and then use the combined prediction to make a final decision. This can be done in a number of ways, such as by averaging the predictions of the individual classifiers, or by using a voting scheme.
There are a number of reasons why combining classifiers can improve accuracy. First, it can help to reduce the variance of the predictions. This is because the predictions of the individual classifiers will often be correlated, and so combining them can help to cancel out some of the noise. Second, combining classifiers can help to improve the bias of the predictions. This is because the individual classifiers may have different biases, and so combining them can help to reduce the overall bias of the model.
However, it is important to note that combining classifiers is not always the best approach. In some cases, it may actually reduce the accuracy of the model. This is because the individual classifiers may be making different mistakes, and so combining their predictions may actually amplify those mistakes. Additionally, combining classifiers can be more complex and computationally expensive than using a single classifier.
Overall, combining classifiers can be a useful technique for improving the accuracy of a classification model. However, it is important to carefully consider the specific application before deciding whether or not to use this approach.
Here are some additional details about each option:
A. Combining classifiers improves interpretability.
This is not always the case. In some cases, combining classifiers can make the model more difficult to interpret. This is because the combined model will be a function of the individual classifiers, and so it may be difficult to understand how the individual classifiers are contributing to the final prediction.
B. Combining classifiers reduces accuracy.
This is also not always the case. In some cases, combining classifiers can improve accuracy. However, as discussed above, it is important to carefully consider the specific application before deciding whether or not to use this approach.
C. Combining classifiers improves accuracy.
This is the correct answer. As discussed above, combining classifiers can be a useful technique for improving the accuracy of a classification model.
D. All of the mentioned.
This is not necessarily the case. In some cases, combining classifiers can improve accuracy, while in other cases it can reduce accuracy. It is important to carefully consider the specific application before deciding whether or not to use this approach.
