Sliding SIR Model for Rt Estimation during COVID Pandemic

One of the main characteristics of an epidemic is the effective reproduction number (Rt), which indicates the number of people each infected individual will further infect at any given time. Being able to estimate Rt is an important task, because this number defines whether the epidemic is expected to grow (Rt>1), or will start declining (Rt<1). In this post, I suggest sliding SIR method of estimation of Rt based on fitting SIR epidemic model to the infections data in different countries. Read More ›

How to Learn Data Science without Coding

Data Science is one of the most demanding and most popular areas of computer science. One might assume that a data scientist need to know Python and programming in general to be successful. While this might be true to a certain extent, in this post we discuss whether Data Science is possible without programming, and how to start learning if you are not a programmer. TL;DR: Microsoft and Udacity just announced a collaboration that will help you with that! Read More ›

DeepPavlov: "Keras" for Natural Language Processing answers COVID Questions

In the field of image-related deep learning, Keras library plays an important role, radically simplifying such tasks as transfer learning or using pre-trained models. If you switch to the area of NLP, to perform relatively complex task such as question answering or intent classification, you would need to put several models at work together. In this post, I describe DeepPavlov library that democratizes NLP, and how to use it with Azure ML to train question answering network on COVID dataset. Read More ›

Using Azure Machine Learning for Hyperparameter Optimization

Most machine learning models are quite complex, containing a number of so-called hyperparameters, such as layers in a neural network, number of neurons in the hidden layers, or dropout rate. To build the best model, we need to chose the combination of those hyperparameters that works best. This process is typically quite tedious and resource-consuming, but Azure Machine Learning can make it much simpler. Read More ›

The Best Way to Start With Azure Machine Learning

I know many data scientists, including myself, who do most of their work on a GPU-enabled machine, either locally or in the cloud, through Jupyter Notebooks or some Python IDE. On the other hand, there is a specific service called Azure ML, made for Machine Learning in the cloud. Many people have heard about it, but most of them think that it is only suitable for large-scale tasks. I can assure you that it is not the case! I have recently learned how to start your journey towards Azure ML painlessly, and will share my experience. Read More ›
