The function seems to be selective for concepts related to chemistry and physics, as indicated by the high values (close to 1) for the words "chemistry" and "physics". It also shows some level of association with the concept of snowboarding, with a value of 0.3242. The function is not selective for the other words provided, as they have relatively low values (close to 0). 

However, it is important to note that this is just a preliminary analysis based on a limited set of inputs. To obtain a more accurate description and understand the function's behavior better, it would be advisable to conduct more experiments with a diverse range of words and categories.
