Theano

Theano is an open-source software library used for building and optimizing mathematical expressions, primarily in machine learning models like neural networks. It enables developers to define complex computations, such as matrix operations, and automatically generate efficient code to execute them on CPUs or GPUs. By doing so, Theano simplifies the process of training models on large datasets and improves computational performance. Think of it as a tool that translates high-level mathematical ideas into fast, hardware-optimized code, facilitating research and development in artificial intelligence and deep learning fields.
