Google's brainchild TensorFlow, in its first year, has more than 6000 open source repositories online. In Keras, a network predicts probabilities (has a built-in softmax function), and its built-in cost functions assume they work with probabilities. In a binary classification problem with data samples from two groups, class imbalance occurs when one class, the minority group, contains significantly fewer samples than the other class, the majority group. Creating a word cloud for your favourite book is even more fun if you are a book lover. 5MB model size” paper. A sample of images from the data set, labeled with their corresponding emotions. AlexNet, proposed by Alex Krizhevsky, uses ReLu(Rectified Linear Unit) for the non-linear part, instead of a Tanh or Sigmoid function which was the earlier standard for traditional neural networks. The model presented in the paper achieves good classification performance across a range of text classification tasks (like Sentiment Analysis) and has since become a standard baseline for new text classification architectures. They suggested slightly distorting the image by shifting or stretching the pixels. And for the Inception V3, we keep only three inception module.
