Published in Analytics Vidhya·Dec 6, 2020Install Tensorflow 2 & PyTorch for AMD GPUsAMD has released ROCm, a Deep Learning driver to run Tensorflow and PyTorch on AMD GPUs. Hence, I provided the installation instructions of Tensorflow and PyTorch for AMD GPUs below. In this post, I guided you to install ROCm (AMD GPU driver) and Tensorflow ROCm (version compatible with AMD hardware)…Tensor Flow3 min read
Published in Analytics Vidhya·Aug 8, 2020Loss Function for Super-Image-Super-Resolution (SISR)In SISR, Autoencoder and U-Net are heavily used; however, they are well-known for difficulties in training to convergence. The choice of loss function plays an important role in guiding models to optimum. Today, I introduce 2 loss functions for Single-Image-Super-Resolution. Zhengyang Lu and Ying Chen published a U-Net model with…Super Resolution4 min read
Published in Analytics Vidhya·Jul 11, 2020Deep Cross Network for Recommendation SystemFor last 2 weeks, I have researched and worked on developing a Video Recommendation System. For many years, Content-based and Collaborative Filtering approaches have been heavily used in Recommendation Systems. Content-based system bases on similarity among items’ characteristics (e.g. cosine similarity) ; and Collaborative Filtering system bases on user-item interactions…Deep Learning5 min read
Published in Analytics Vidhya·Apr 13, 2020Classification Loss: Cross-EntropyI have recently worked on Computer Vision projects for classification tasks. Papers and tutorials mention Cross Entropy as the mostly used loss function to measure the difference between predictions and labels. Now, the question is what, how, and why we use Cross Entropy? This article is based on the Classify…Cross Entropy3 min read
Published in Analytics Vidhya·Feb 9, 2020Computer Vision Series: Geometric TransformationLook familiar? He is Sherlock Holmes with his magnifier to “zoom in” tiny details on the sculpture. In 21st century, computers are capable of 100x zoom that is much better than Holmes’s magnifier. As an engineer, my question is how computers zoom in or zoom out? Geometric Transformation Geometric transformation is to…Python 35 min read
Published in Analytics Vidhya·Feb 2, 2020Computer Vision: SegmentationToday is another Image Processing algorithm: Segmentation by Thresholding. Many of you properly are fans of Marvel’s or DC’s World of Superheros. Let’s look at a random scene of Superman: Yup! You are seeing the CGI technology. In this article, let’s say that you and I want to segment Superman…Python 34 min read
Published in Analytics Vidhya·Jan 27, 2020Computer Vision Series: Histogram EqualizationSome of you reading this post have posted several pictures on Instagram and used built-in tools to increase/decrease brightness, contrast, gamma, and etc. to make your boring shots more beautiful, detailed, and attractive. I did several times, and I questioned myself how computers were able to do it. …Computer Vision4 min read
