Nearest neighbor interpolation is computationally efficient but not as accurate as bilinear or bicubic interpolation. Bilinear Interpolation For bilinear interpolation, the block uses the weighted average of two translated pixel values for each output pixel value. Note. In some circumstances when using the CUDA backend with CuDNN, this operator may select a nondeterministic algorithm to increase performance.

K nearest neighbors or KNN Algorithm is a simple algorithm which uses the entire dataset in its training phase. Whenever a prediction is required for an unseen data instance, it searches through the entire training dataset for k-most similar instances and the data with the most similar instance is finally returned as the prediction.
