The field of information theory defines entropy as a measure of average information a random variable takes. As we know the random variable is one whose possible outcome states are not deterministic. We cannot predict its behavior exactly in an analytical form. In such cases, we can only look at the patterns of its outcome …
This article is a tutorial on the algorithm called active Learning with uncertainty Sampling. Introduction Availability of mass quantities of digital data and feasible computing power brought to the creation of learning algorithms. These learning algorithms have been benchmarked to perform specialized tasks such as classification, object detection, image segmentation, etc. The key assumption here …

This article is a review of active learning which is a subfield of machine learning Introduction The field of Machine Learning (ML) broadly deals with giving computers the ability to do tasks like humans. We are seeing a human-level performance in specialized tasks such as speech recognition, image recognition, etc. Many sub-fields of ML are …
The topic I wish to talk in this post is about Mathematical maturity. It is connected to the abstract nature of mathematics and humans’ endeavor to cope with it. Let me start by asking you a question. Have you ever seen a circle in real-life?. You might say yes because we all draw many in …
Why does it need to look for an alternate cooling technology? Cooling appliances based on thermodynamic cycle till 1995 used to produce many toxic components Chloroflurocarbon CFC), Hydrochloroflurocarbon (HCFC), potent greenhouse gases (GHG) and other ozone depleting substances (ODC). After gradual prohibition of such gases, the cooling appliances till date producing HFCs which have no …
What calls for an advanced technology based on electron spin? Electronics use the property of electrons called charge to encode information. One way computers store information is by using RAM. RAM is comprised of billions of capacitors and to store information computer sends a large number of electrons which are absorbed by the capacitor plate …
The Center for Brains, Minds and Machines (CBMM) is a premier institute and NSF Science and Technology Center dedicated to the study of intelligence. The website and Youtube channel of the institute contains a good number of tutorials and educational materials that help anyone interested in topics related to neuroscience, machine intelligence, etc. One of …

Introduction Divide and conquer seem the most widely used strategy to attack hard problems. The use of this idea and similar approaches are ample in every discipline. In this post, let’s look at how this concept is a cornerstone in analyzing signals and systems. Consider the case of audio signals. We can think of them …
Nanotechnology deals with the science of building small, but why do we talk about such small things? Well, they ultimately constitute the world we live in and we can explore fascinating things with them, literally, it can shape the world around us. Properties of materials change due to quantum effects when they are made small, …

In one of our earlier posts, we have seen how we can visually relate the parts of the one-dimensional Gaussian distribution equation. In this post, we will follow the same strategy to understand the terms that comes up with a Multivariable Gaussian distribution. We will focus on the Bivariate Gaussian distribution as distributions of higher-order …
