WebFeb 17, 2024 · 6. Cross-validation for time series data. We know that time-series data is different. When doing time series forecasting our objective is to build a model that is capable of predicting the future from some past observations. While validating time series models one should always keep only out-of-time samples in the validation/test set. WebDescription: 1 AI: Adopting AI models on financial time series data. Use pandas,sklearn on data preprocessing, data mining and machine learning (algorithms including random forest, naive bayes, SVM, NN, etc.). Use te nsorflow for deep learning (algorithms include cnn, rnn, etc.). Track and learn latest algorithms for machi ne learning.
