It is a multi-layer neural network designed to analyze visual inputs and perform tasks such as image classification, segmentation and object detection, which can be useful for autonomous vehicles. Li Xu Jimmy SJ. To solve the problem of the low scale invariance, we will try to increase the number of convolutional layers in future projects and use the most representative dataset. Once the network parameters have converged an additional training step is performed using the in-domain data to fine-tune the network weights. If you're a seasoned follower of my blog, you may know that I don't really like Tensorflow on microcontrollers, because it is often "over-sized" for the project at hand and there are leaner, faster alternatives. Deep Convolutional Neural Network (CNN) is a special type of Neural Networks, which has shown exemplary performance on several competitions related to … The idea is that a small kernel window is moved over neurons from a prior layer.
