 tf_cnnvis is a CNN visualization library which you can use to better understand your own CNNs. We use the [TensorFlow](https://www.tensorflow.org/) library at the backend and the generated images are displayed in [TensorBoard](https://www.tensorflow.org/get_started/summaries_and_tensorboard). We have implemented 2 CNN visualization techniques so far:
 
 1) Based on the paper [Visualizing and Understanding Convolutional Networks](https://www.cs.nyu.edu/~fergus/papers/zeilerECCV2014.pdf) by Matthew D. Zeiler and Rob Fergus. The goal here is to reconstruct the input image from the information contained in any given layers of the convolutional neural network. Here are a few examples
