摘要： Theano is a Python library that allows you to define, optimize, and evaluate mathematical expressions involving multi-dimensional arrays efficiently. Theano features: •tight integration with NumPy – Use numpy.ndarray in Theano-compiled functions. •transparent use of a GPU – Perform data-intensive calculations up to 140x faster than with CPU.(float32 only) •efficient symbolic differentiation – Theano does your derivatives for function with one or many inputs. •speed and stability optimization 阅读全文
