In the previous article, I discussed the basic theories and concepts regarding time series analysis and forecasting. And also gave an intuition to some univariate time series forecasting models such as AR, MA, ARMA, ARIMA and SARIMA. You can go through it using the below link.
I just finished a research work on time series forecasting and in that, I have to look for some multivariate time series techniques. I thought it would be beneficial to document my findings on Vector Auto Regression for someone who is getting started with a multivariate time series forecasting. …
Time-series forecasting is one of the important areas of machine learning. This is very important when it comes to prediction problems that involve a time component.
These days I am doing my project task based on time series analysis and forecasting. So, I did some research on this area and thought it would be beneficial to me and also people who are getting started with time series forecasting to make those findings in some documented manner.
The purpose of this article is to give an introduction to time series, and basic concepts and modelling techniques related to time series analysis…
Elasticsearch is the heart of today’s most popular log analytics platform, the ELK Stack. In this article, I will explain what Elasticsearch is and what are the use cases of Elasticsearch.
Elasticsearch is a distributed, open source search and analytics engine for all types of data, including textual, numerical, geospatial, structured, and unstructured.
Elasticsearch is built on Apache Lucene. It was first released in 2010 by Elasticsearch N.V. Elasticsearch is an open-source project developed in Java and managed by Elastic. The codebase includes contributions from developers both inside and outside of Elastic.
Elasticsearch supports a variety of languages and official…
In this article, I will discuss monolithic and microservices-based architectures and the pros and cons of them.
I had a chance to work on an application based on microservices architecture during my internship. I have contributed to some existing microservices as well as worked with a newly added microservice used for authentication. You can refer to some of my experiences got from the authentication service from the below link.
From the learning I got from working with those things, I did some digging on microservices architecture as well as monolithic (traditional) architecture.
First, we look at what the word ‘monolithic’…
In this post, I will explain about JSON web tokens and how it can be used in the authentication.
JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object. This information can be verified and trusted because it is digitally signed. JWTs can be signed using a secret (with the HMAC algorithm) or a public/private key pair using RSA or ECDSA.
JSON Web Tokens can be used to authorize and exchange information between parties.
