Deep learning (multi layer artificial neural network) is a sub-branch of machine learning that enables learning from large data sets with its layered architecture. Increased processor speeds and storage, inexpensive computer hardware and machine learning gains are factors that boost deep learning development. Gradient Descent based optimization algorithms(Stochastic gradient descent (SGD), Momentum, Adam, Adagrad, RMSProp and Adadelta) used to minimize error in deep learning are also part of this success.
In this study, deep learning and optimization algorithms were applied to the caltech 101 data set, which is an international data set. Relu was used as activation function and cross entropy was preferred as loss function. Images are resized to 64x64. Each time the program is run, a random six category image is taken and 100 iterations are executed. Different results were obtained with optimization algorithms and these results were analyzed. The success rates in classification were observed as SGD: 64.5%, Momentum: 85.56%, Adam: 92.31%, Adagrad: 71.25%, RMSProp: 40.26% and Adadelta: 86.88%.
