WitrynaNaive Bayes # Naive Bayes is a multiclass classifier. Based on Bayes’ theorem, it assumes that there is strong (naive) independence between every pair of features. Input Columns # Param name Type Default Description featuresCol Vector "features" Feature vector. labelCol Integer "label" Label to predict. Output Columns # Param name Type … WitrynaNaïve method. For naïve forecasts, we simply set all forecasts to be the value of the last observation. That is, ^yT +h T = yT. y ^ T + h T = y T. This method works remarkably well for many economic and financial time series. naive(y, h) rwf(y, h) # Equivalent alternative. Because a naïve forecast is optimal when data follow a random walk ...
