Training a neural network involves minimizing its error with respect to its parameters, and since larger neural networks may have millions of parameters, this poses quite a challenge. Surprisingly, many of the recent advances in neural networks come not from improved data processing, neural network architectures, or other machine learning tricks, but instead from incredibly powerful methods for function minimization. In this notebook, we'll go through several optimization methods and work our way up to, a powerful optimization method adapted to neural networks by James Martens in 2010. Conclusion With the modifications from the previous section, the Hessian Free method becomes applicable to many-dimensional optimization problems. In his, James Martens discusses a number of other optimizations and modifications to that method, but they rely on the exact same structure and intuition as the unmodified method presented above.
