Conditional Classification: A Solution for Computational Energy Reduction
This addresses the issue of computational energy reduction for users of deep learning models in resource-constrained environments, though it is incremental as it builds on existing classification techniques.
The paper tackles the problem of high computational complexity in deep convolutional neural networks for many-class image classification by proposing a two-step conditional classification method, achieving comparable accuracy to state-of-the-art models with reduced computational complexity (Flop Count).
Deep convolutional neural networks have shown high efficiency in computer visions and other applications. However, with the increase in the depth of the networks, the computational complexity is growing exponentially. In this paper, we propose a novel solution to reduce the computational complexity of convolutional neural network models used for many class image classification. Our proposed technique breaks the classification task into two steps: 1) coarse-grain classification, in which the input samples are classified among a set of hyper-classes, 2) fine-grain classification, in which the final labels are predicted among those hyper-classes detected at the first step. We illustrate that our proposed classifier can reach the level of accuracy reported by the best in class classification models with less computational complexity (Flop Count) by only activating parts of the model that are needed for the image classification.
