How to tune hyperparameters of random forest with panel data in python? Is there an already implemented package and function? I have looked for answers among others in: https://towardsdatascience.com/time-series-nested-cross-validation-76adba623eb9 https://stats.stackexchange.com/questions/3262...
Random Forest for Time Series In this section, we will explore how to use the Random Forest regressor for time series forecasting. We will use a standard univariate time series dataset with the intent of using the model to make a one-step forecast. You can use the code in this section as...

Conclusions Random Forest time series modeling provides enhanced predictive ability over existing time series models for the prediction of infectious disease outbreaks. This result, along with those showing the concordance between bird and human outbreaks (Rabinowitz et al. 2012), provides a new ...
Randomness is injected to the learning process by randomly choosing time segment (column in the matrix) and lag p for each tree in the random forest. A bag-of-words type compressed representation is created from the output of the leaf-nodes for each tree. The final time series representation...

Random forest is a machine learning algorithm implemented in time series forecasting; however, most of its forecasting properties have remained unexplored. Here we focus on assessing the performance of random forests in one-step forecasting using two large datasets of short time series with the aim ...
