#### Fine-tuning Convolutional Neural Network on own data using Keras Tensorflow

Keras is winning the world of deep learning. In this tutorial, we shall learn how to use Keras and transfer learning to produce state-of-the-art results using very small datasets. We shall provide complete training and prediction code. For this comprehensive guide, we shall be using VGG network but the techniques learned here can be used […]

Continue Reading#### Freeze Tensorflow models and serve on web

In this tutorial, we shall learn how to freeze a trained Tensorflow Model and serve it on a webserver. You can do this for any network you have trained but we shall use the trained model for dog/cat classification in this earlier tutorial and serve it on a python Flask webserver. So you trained a new […]

Continue Reading#### ResNet, AlexNet, VGG, Inception: Understanding various architectures of Convolutional Networks

Convolutional neural networks are fantastic for visual recognition tasks. Good ConvNets are beasts with millions of parameters and many hidden layers. In fact, a bad rule of thumb is: ‘higher the number of hidden layers, better the network’. AlexNet, VGG, Inception, ResNet are some of the popular networks. Why do these networks work so well? How are they […]

Continue Reading#### Image Segmentation using deconvolution layer in Tensorflow

In this series of post, we shall learn the algorithm for image segmentation and implementation of the same using Tensorflow. This is the first part of the series where we shall focus on understanding and be implementing a deconvolutional/fractional-strided-convolutional layer in Tensorflow. Why is deconvolutional layer so important? Image segmentation is just one of […]

Keras is a high-level python API which can be used to quickly build and train neural networks using either Tensorflow or Theano as back-end. This tutorial assumes that you are slightly familiar convolutional neural networks. You can follow the first part of convolutional neural network tutorial to learn more about them. In this quick tutorial, we shall […]

Continue Reading#### Accelerating Convolutional Neural Networks on Raspberry Pi

Unless you have been living under the rock, you must have heard of the revolution that deep learning and convolutional neural networks have brought in computer vision. Computers have achieved near-human level accuracy for most of the tasks. However, most of the top performing neural networks for state of the art image recognition problem suffer […]
