Manipulation, Utility and Advantages of Graph Neural Networks — Graph neural networks (GNN) are gaining popularity due to the ubiquitous nature of the Graph Data structure. Graphs enable us to model many different problems in science in fields such as (but not limited to) biology, sociology, ecology, vision, education, economics, etc. …

Introduction to variational autoencoders and their application Bioinformatics/Metagenomics analysis — Autoencoders, in general, intend to learn a lower-dimensional representation of data. One of the main advantages of autoencoders is that they are capable of learning much complex lower dimensions whereas PCA-like decompositions are limited by their linear nature. Feel free to have a look at my article about auto-encoders.

An in-depth exploration of sequence vectorization and applications — In one of my previous articles, I mentioned how and what is vectorization. In gist, the process enables us to convert variable-length nucleotide sequences into fixed-length numeric vectors. For all the programming lovers, the link is below; Vectorization of DNA sequences Efficient conversion of ACGT sequences into k-mer frequency vectorsmedium.com

Super-fast and parallel file writing with memory mapped IO — What is a Memory Mapped File? A memory mapped file is a segment in the virtual memory. Virtual memory is an abstraction on physical memory which is provided to the process by the operating system (OS). Should the OS run out of memory or see a process idling for long, such virtual memory segments will be…

A tool to generate annotated images for computer vision — In computer vision, object detection is an interesting field with numerous application. Like any other supervised machine learning task, we need annotation or labels for this very task as well. However, annotation of images can be a tedious time-consuming task for many of us (lazy ones?). …

Object detection with AIoT: An edge computing example — A few weeks back when I was window shopping at AliExpress I came across the wonderful Maixduino device. It was claimed to carry RISC V architecture along with a KPU (KPU is a general-purpose neural network processor). Contrasting specs of the board were as follows; CPU: RISC-V Dual Core 64bit…

Building an MQTT enabled door sensor using ESP32 and PlatformIO — This article is motivated by my previous article on ESPHome. Previously, we built a door sensor using ESPHome library. However, using an off-the-shelf platform grants us with little to no flexibility when it comes to micro-optimizations. …

Create simple home automation artefacts using ESP modules and HomeAssistant — Home automation can be expensive and complex. However, with the arrival of IoT platforms from vendors such as Tuya, Phillips, etc have made home automation a little simpler. However, the cost still remains a little higher and the customisations are far limited. Last but not least, none of the mentioned…

Build your own Smart TV with the help of a Raspberry Pi Zero device — Are you bored with your ordinary TV? Do you want to expand your media experience to a whole new level? Yet you are limited with the budget? Like me? Well, this would be the perfect Smart TV solution! Disclaimer: This tutorial might not be complete and can contain differences. Google…
