KNN regression #269

Open cydcydcyd opened 5 years ago

cydcydcyd commented 5 years ago

hello, I refer to the example of KNN classification and use KNN for regression. here is my code: KDTree<RealVector> tree(data.inputs()); TreeNearestNeighbors<RealVector, RealVector> algo(data, &tree); const unsigned int K = 5; // number of neighbors for kNN NearestNeighborModel<RealVector, RealVector> KNN(&algo, K); Data<RealVector> testInputs = spAver.matToRealVector(fMat); Data<RealVector> pred = KNN(testInputs);

when prediction starts, some thing wrong happened: Exception thrown at 0x0000000000000274 in cellDemo.exe: 0xC0000005: Access violation executing location 0x0000000000000274. image

can me help me?thanks! @Ulfgard

thanks for reminding me of this. I have it already fixed, but am currently not at my work station. The errors are multi-thread related. Sorry for this.
