Key techniques include vectorized operations for activation functions, broadcasting for batch normalization, matrix multiplication for neural network layers, boolean masking for data filtering, argmax for classification predictions, and einsum for complex tensor operations. These operations significantly improve computational efficiency when working with large datasets and model parameters. ## Full article daily.dev links to this article rather than hosting it.
