However, this technique has a number of disadvantages, being the low computational efficiency the most prominent one.

This paper presents a strategy to what is multi class classification this obstacle in multi-class classification tasks. This strategy proposes the use of Prototype Reduction algorithms what is multi class classification are capable of generating a new training set from the original one to try to gather the same information with fewer samples. Over this reduced set, it is estimated which classes are the closest rd sharma class 11 sets examples to the input sample.

These classes are referred to as promising classes. Eventually, classification is performed using the original training set using the nearest neighbor rule but restricted to the promising classes. Our experiments with several datasets and significance tests show that a similar classification accuracy can be obtained compared to using the original training set, with a significantly higher efficiency.
