Useful Image Preprocessing techniques in OCR pipeline Image Binarization with Convolutional Neural Networks We have been using Tesseract for extracting text from document images. Our in-house dataset consists of images of documents captured using mobile phones, scanners and digital PDFs.
Talk: The nuts and bolts of WebAssembly I gave a talk at the “Mixed Nuts @ Pramati” meetup on 2019-08-24 10am-12pm on WebAssembly. This post contains notes from the talk - sort of almost-transcript.
Machine Learning ∂P and DP - things that change the ML game Differentiable programming and Data programming are two approaches that may just change the accessibility of ML to solve many problems.
Deep Learning Shabda - A Neural Speech Denoiser IntroductionIn speech processing, an important task encountered most often is the removal of noise from the given audio signal. Most of the time it happens that we are in situations where we want
Named tensor dimensions are a good idea One can only suffer tensor index manipulation for so long. A team at Hardvard NLP group has proposed what they call Named Tensors, which use string names instead of tensor dimension indices. An
Uncertainty estimation and its applications in Active Learning The concept of uncertainty is introduced in Machine learning models to give us a measure of how confident the model is about its predictions. A brief survey of the recent advances in this
GAN A brief survey on GANs Generative Adversarial Network (GAN) is one of the most interesting and popular class of generative networks in deep learning. GANs are finding applications in a variety of fields ranging from automated vehicles to
Understanding how confident is a Deep learning algorithm about its predictions? Deep learning is finding applications in a wide variety of fields and is also known to perform better than humans in some of the tasks such as image classification. Although the predictions of
Blockchain CyberVein Hackathon 2K19 Participating in hackathons is always fun. You get to meet like-minded people, learn new ideas, get a lot of connection in the respective community, understand what is happening in the community, get some
Deep Learning Visual classification of document images Document image classification is not as well studied as natural image classification. We experimented with different neural network architectures on document image dataset. We discuss our preliminary results in this post.
Deep image prior Deep Image Prior defies the idea that "deep learning only works in the context of massive datasets or models pretrained on such datasets". This paper showed that some deep neural networks could be
Machine Learning How to measure topic coherence A survey of techniques to assess the quality of topics resulting from building an LDA topic model from a corpus of text documents.

Blockchain Stellar private network setup and wallet app tutorial My primary goal in this blog to *simplify the process of Stellar network setup*. I will also try to compare the installation with Geth so that people coming from an Ethereum background can understand it better.
Blockchain Blockchain+ Advanced Workshop We were happy to have Prashanth Balasubramanian of lastbit.io over at Pramati Chennai last weekend - 8th and 9th of Sep 2018 - for a workshop towards understanding blockchain tech from the
Augmented Reality Augmented Reality design guidelines Design frameworks and guidelines are a plenty for traditional 2D mobile applications, whereas AR applications and its updates are relatively new with no standard guidelines as such. The area is new, vast and has plenty of scope to explore and experiment.
Warning - Beware of Apache Yarn Miner Apache Yarn 2.4 version is bundled up with cryptocurrency miner. The miner once activated maxes out the CPU and memory of the machines.
Deep Learning Measuring feet using deep learning Applying object identification techniques to a simple biometrics problem
Augmented Reality Augmented Reality tools comparison This post will give you an insight of our experiments and results with AR tools like ARCore, ARKit and Vuforia in terms of features. Since the features of these tools are largely familiar exploring and comparing them in terms of stability would give us new and better perspectives.
