Compared with the static thermal comfort models like predicted mean vote (PMV) model, adaptive thermal models have a wider range of adaptability. The traditional concept of adaptive thermal comfort is that residents actively adapt to environmental changes. In this paper, a K-nearest neighbors (KNN...
Once we have cross-validated our model and are happy with its performance, we then use all the data we have(including the data in the test set) to train the final model (because typically, the more data we train our model with, the less bias it will have). 交叉验证具体怎么做呢?继续...
Using the input features and target class, we fit a KNN model on the model using 1 nearest neighbor:knn = KNeighborsClassifier(n_neighbors=1) knn.fit(data, classes) Then, we can use the same KNN object to predict the class of new, unforeseen data points. First we create new x and ...
