PyTorch’s Scatter_() Function + One-Hot Encoding (A Visual Explanation)

The way PyTorch’s scatter_(dim, index, src) function works can be a bit confusing. So, I will take a visual approach in explaining the function as I believe it will be more clearer in grasping the concept further. The scatter_() function takes three arguments: The dimension across which we will be…

Do We Need Fuzzy Logic In Our Databases?

I was reading in Bart Kosko’s book: Fuzzy Thinking, where he mentioned that in much of our science, math, logic, and culture, we have assumed a world of blacks and whites that doesn’t change. In other words, everything is either true or false. …

Deep Learning to Transform Melanoma Detection: It is Closer Than You Think

In an interview I conducted with Jürgen Schmidhuber, a German computer scientist and artist known for his work in many fields including machine learning, Artificial Intelligence (AI), and artificial neural networks, I asked him where he sees Deep Learning (a form of machine learning) in the coming 10-years. I got…

CNN With Transfer Learning for Melanoma Detection Using Keras

I will be sharing a script using Keras for training a Convolutional Neural Network (CNN) with transfer learning for melanoma detection. You can find the code in this GitHub repository. In the previous post, the CNN was trained from scratch without augmenting the data. Before proceeding, make sure that you…

GANMole for generating melanoma images Using Keras

I used a Generative Adversarial Network (GAN) to generate melanoma images, and named the code GANMole. You can find the code on the GANMole GitHub repository. I used 374 images to train the GAN, and have resized the images to 32x32 due to the resource exhaustion I get faced with on the GPU I’m using when going with higher resolution images. You can download the images from, here. I would like to mention that I have renamed the images into sequenced number images, that is 0.jpg, 1.jpg, 2.jpg, …, 373.jpg. You can use this script to rename the image file names to sequence number names.

A Smooth Introduction to Linear Regression and its Implementation in PyTorch (Part-II)

So in Part-I I gave a simple introduction on what linear regression is and how we can find the equation of the best fit line for our data. In this post, I will show you how to implement the task we worked on in Part-I in PyTorch. …

A Smooth Introduction to Linear Regression and its Implementation in PyTorch (Part-I)

The term linear regression might seem a bit complex at first, but don’t worry, it is a simple but powerful concept. Let us go through an example to understand the concept better. I will throw some random data here and see what happens. Say that we have two variables h…
