What is Classification in Data Mining? Classification is a fundamental concept in the field of data mining. It refers to the process of categorizing or grouping data instances into predefined classes or categories based on their characteristics or attributes. Imagine you have a collection of fruits...

Statistical data-mining (DM) and machine learning (ML) are promising tools to assist in the analysis of complex dataset. In recent decades, in the precision of agricultural development, plant phenomics study is crucial for high-throughput phenotypin
In data mining, classification and prediction are mostly applied for future planning and analysis of current trends. Data mining is a wider concept that contains different steps: Firstly data is pre-processed, where missing values are normalized, missing labels are rectified and noise will be ...
