About: A Python library that allows you to define, optimize, and evaluate mathematical expressions involving multi-dimensional arrays efficiently. Dynamically generates CPU and GPU modules for good performance. Deep Learning Tutorials illustrate deep learning with Theano.

Theano 1.0.2 (23rd of May, 2018)

This is a maintenance release of Theano, version 1.0.2, with no new features, but some important bug fixes.

We recommend that everybody update to this version.

Highlights (since 1.0.1):

• Theano should work under PyPy now (this is experimental).
• Update for cuDNN 7.1 RNN API changes.
• Fix for a crash related to mixed dtypes with cuDNN convolutions.
• MAGMA should work in more cases without manual config.
• Handle reductions with non-default accumulator dtype better on the GPU.
• Improvements to the test suite so that it fails less often due to random chance.

• Frederic Bastien
• Steven Bocco
• Jon Haygood
• Arnaud Bergeron
• Jordan Melendez

About: DiffSharp is a functional automatic differentiation (AD) library providing gradients, Hessians, Jacobians, directional derivatives, and matrix-free Hessian- and Jacobian-vector products as higher-order functions. It allows exact and efficient calculation of derivatives, with support for nesting.

Fixed: Bug fix in forward AD implementation of Sigmoid and ReLU for D, DV, and DM (fixes #16, thank you @mrakgr)

Improvement: Performance improvement by removing several more Parallel.For and Array.Parallel.map operations, working better with OpenBLAS multithreading

Added: Operations involving incompatible dimensions of DV and DM will now throw exceptions for warning the user
