Oct 21, 2019 · The framework makes use of efficient and convenient Python libraries and functions, including numpy arrays and numpy.einsum(), which is an implementation of the Einstein summation convention that greatly facilitates the programming of parameter equations and pandas for metadata handling. The GIL is released for all np.einsum variations. Some specific loop structures which have an accelerated loop version did not release the GIL prior to NumPy 1.14.0. This oversight has been fixed. The np.einsum function will use BLAS when possible and optimize by default. The np.einsum function will now call np.tensordot when appropriate.

Einstein Summation

einsum has C iteration speed, but the actual matrix multiplication cannot match BLAS, even though it uses SIMD to be faster than a naive C implementation. Probably best for big n and small g . iteration plus dot is slow iterating, but fast multiplying (if you have a good BLAS library), so best for small n and large g .

Aug 09, 2019 · Arrays with different sizes cannot be added, subtracted, or generally be used in arithmetic. A way to overcome this is to duplicate the smaller array so that it is the dimensionality and size as the larger array. This is called array broadcasting and is available in NumPy when performing array arithmetic, which can greatly reduce […]

Sep 09, 2020 · The way to compute m1 * m2 using einsum() is m1m2 = np.einsum(“ij, jk -> ik”, m1, m2). The part in the quotes assigns labels to the dimensions of the input matrices and specifies the output shape. The letters are arbitrary so an equivalent expression is m1m2 = np.einsum(“ab, bc -> ac”, m1, m2). Now suppose matrix m1 has dimensions (2,3,4).

In this paper, we propose Einsum Networks (EiNets), a novel implementation design for PCs, improving prior art in several regards. At their core, EiNets combine a large number of arithmetic operations in a single monolithic einsum-operation, leading to speedups and memory savings of up to two orders of magnitude, in comparison to previous implementations. Model averaging is an approach to ensemble learning where each ensemble member contributes an equal amount to the final prediction. In the case of regression, the ensemble prediction is calculated as the average of the member predictions. In the case of predicting a class label, the prediction is calculated as the mode of the member predictions.
