One of the main problems of neural networks is to tame layer activations so that one is able to obtain stable gradients to learn faster without any confining factor. Batch Normalization shows us that keeping values with mean 0 and variance 1 seems to work things. However, albeit indisputable effectiveness of BN, it adds more … Continue reading Paper Review: Self-Normalizing Neural Networks
paper: https://arxiv.org/abs/1702.08591 The whole heading of the paper is "The Shattered Gradients Problem: If resnets are the answer, then what is the question?". It is really interesting work with all its findings about gradient dynamics of neural networks. It also examines Batch Normalization (BN) and Residual Networks (Resnet) under this problem. The problem, dubbed "Shattered Gradients", described as … Continue reading Paper Notes: The Shattered Gradients Problem ...
In simple terms, dilated convolution is just a convolution applied to input with defined gaps. With this definitions, given our input is an 2D image, dilation rate k=1 is normal convolution and k=2 means skipping one pixel per input and k=4 means skipping 3 pixels. The best to see the figures below with the same k … Continue reading Dilated Convolution
What is Adversarial? Machine learning is everywhere and we are amazed with capabilities of these algorithms. However, they are not great and sometimes they behave so dumb. For instance, let's consider an image recognition model. This model induces really high empirical performance and it works great for normal images. Nevertheless, it might fail when you change … Continue reading Ensembling Against Adversarial Instances
Paper: https://arxiv.org/abs/1312.6199 This paper studies description of semantic information with higher level units of an network and blind spot of the network models againt adversarial instances. They illustrate the learned semantics inferring maximally activating instances per unit. They also interpret the effect of adversarial examples and their generalization on different network architectures and datasets. Findings … Continue reading Paper Notes: Intriguing Properties of Neural Networks
Suppose you have a problem that you like to tackle with machine learning and use the resulting system in a real-life project. I like to share my simple pathway for such purpose, in order to provide a basic guide to beginners and keep these things as a reminder to myself. These rules are tricky since even-thought … Continue reading Short guide to deploy Machine Learning
Selfies are everywhere. With different fun masks, poses and filters, it goes crazy. When we coincide with any of these selfies, we automatically give an intuitive score regarding the quality and beauty of the selfie. However, it is not really possible to describe what makes a beautiful selfie. There are some obvious attributes but they are not fully prescribed. With … Continue reading Selfai: A Method for Understanding Beauty in Selfies
Paper: https://arxiv.org/pdf/1611.03530v1.pdf This paper states the following phrase. Traditional machine learning frameworks (VC dimensions, Rademacher complexity etc.) trying to explain how learning occurs are not very explanatory for the success of deep learning models and we need more understanding looking from different perspectives. They rely on following empirical observations; Deep networks are able to learn … Continue reading Paper review - Understanding Deep Learning Requires Rethinking Generalization
A crucial problem in a real DL system design is to capture test data distribution with the trained model which only sees the training data distribution. Therefore, it is always important to find a good data splitting scheme which at least gives the right measures to such divergence. It is always a waste to spend … Continue reading Important Nuances to Train Deep Learning Models.
