- 가우스 과정 회귀 모델
가우스 과정 회귀(GPR) 모델은 비모수 커널 기반의 확률적 모델입니다.
- 커널(공분산) 함수 옵션
가우스 과정에서 공분산 함수는 유사한 예측 변수 값을 가진 점들은 유사한 응답 변수 값을 가질 것이라는 기대치를 표현합니다.
- Exact GPR Method
Learn the parameter estimation and prediction in exact GPR method.
- Subset of Data Approximation for GPR Models
With large data sets, the subset of data approximation method can greatly reduce the time required to train a Gaussian process regression model.
- Subset of Regressors Approximation for GPR Models
The subset of regressors approximation method replaces the exact kernel function by an approximation.
- Fully Independent Conditional Approximation for GPR Models
The fully independent conditional (FIC) approximation is a way of systematically approximating the true GPR kernel function in a way that avoids the predictive variance problem of the SR approximation while still maintaining a valid Gaussian process.
- Block Coordinate Descent Approximation for GPR Models
Block coordinate descent approximation is another approximation method used to reduce computation time with large data sets.
- Predict Responses Using RegressionGP Predict Block
Train a Gaussian process (GP) regression model, and then use the RegressionGP Predict block for response prediction.
