Splet08. okt. 1997 · Computer Science. Support Vector Machines are used for time series prediction and compared to radial basis function networks. We make use of two different cost functions for Support Vectors: training with (i) an e insensitive loss and (ii) Huber's robust loss function and discuss how to choose the regularization parameters in these … Splet29. maj 2024 · Introduction to Time Series The objective of a predictive model is to estimate the value of an unknown variable. A time series has time (t) as an independent variable (in any unit you can think of) and a target dependent variable . The output of the model is the predicted value for y at time t .
