Support vector regression with asymmetric loss for optimal electric load forecasting
نویسندگان
چکیده
In energy demand forecasting, the objective function is often symmetric, implying that over-prediction errors and under-prediction have same consequences. practice, these two types of generally incur very different costs. To accommodate this, we propose a machine learning algorithm with cost-oriented asymmetric loss in training procedure. Specifically, develop new support vector regression incorporating linear-linear cost insensitivity parameter for sufficient fitting. The electric load data from state New South Wales Australia used to show superiority our proposed framework. Compared basic regression, framework multi-step forecasting results daily economic reduction ranging 42.19% 57.39%, depending on actual ratio errors.

Optimal training subset in a support vector regression electric load forecasting model
This paper presents an optimal training subset for support vector regression (SVR) under deregulated power, which has a distinct advantage over SVR based on the full training set, since it solves the problem of large sample memory complexity O(N2) and prevents over-fitting during unbalanced data regression. To compute the proposed optimal training subset, an approximation convexity optimization...

متن کاملShort Term Load Forecasting Using Empirical Mode Decomposition, Wavelet Transform and Support Vector Regression
The Short-term forecasting of electric load plays an important role in designing and operation of power systems. Due to the nature of the short-term electric load time series (nonlinear, non-constant, and non-seasonal), accurate prediction of the load is very challenging. In this article, a method for short-term daily and hourly load forecasting is proposed. In this method, in the first step, t...
متن کاملSupport Vector Regression in Forecasting
Support Vector Regression (SVR), a category for Support Vector Machine (SVM) attempts to minimize the generalization error bound so as to achieve generalized performance. Regression is that of finding a function which approximates mapping from an input domain to the real numbers on the basis of a training sample. Support vector regression is the natural extension of large margin kernel methods ...
