WebAug 23, 2024 · Entropy is the measure of disorder and randomness in a closed [atomic or molecular] system. [1] In other words, a high value of entropy means that the randomness in your system is high, meaning it is difficult to predict the state of atoms or molecules in it. On the other hand, if the entropy is low, predicting that state is much easier. WebDive into the research topics of 'Crop prediction using machine learning'.
