چکیده

We introduce second-order methods for training and pruning of general Boltzmann networks trained with cross-entropy error. In particular, we derive the second derivatives for the entropic cost function. We illustrate pruning on Boltzmann zippers, applied to real-world data | a speechreading (lipreading) problem.

A Hybrid Algorithm based on Deep Learning and Restricted Boltzmann Machine for Car Semantic Segmentation from Unmanned Aerial Vehicles (UAVs)-based Thermal Infrared Images

Nowadays, ground vehicle monitoring (GVM) is one of the areas of application in the intelligent traffic control system using image processing methods. In this context, the use of unmanned aerial vehicles based on thermal infrared (UAV-TIR) images is one of the optimal options for GVM due to the suitable spatial resolution, cost-effective and low volume of images. The methods that have been prop...

Hessian Free Deep Learning

Optimization techniques used in Machine Learning play an important role in the training of the Neural Network in regression and classification tasks. Predominantly, first order optimization methods such as Gradient Descent have been used in the training of Neural Networks, since second order methods, such as Newton’s method, are computationally infeasible. However, second order methods show muc...
