Fake news is one of the biggest threats in the modern world. With the advent of social media, it has become effortless to create and dissemiate information. However, verifying the authenticity of this information is a daunting task, requiring extensive applications of techniques from knowledge modeling and artificial intelligence. Recently, stance based fake news detection using transformer based language models have gained attention. However, the performance of these techniques on existing datasets remains comparatively low. The use of ensemble techniques, knowledge modeling, and explainable AI can improve the existing techniques considerably.

Link to my paper on the use of transformer ensembles for detecting Hindi fake news can be found here.

Experienced readers can quickly deduce the author of a prose - nightmarish scenarios are inherently Kafka-esque, while long, complex sentences where delve into a character's consciousness is considered classic Dostoevsky prose. Writing style is often considered to be unique enough to pinpoint the author. Authorship attribution, at its very core aims to do just that - given a particular piece of text and a set of candidate authors, we aim to predict the author of the given piece of text. Although traditionally dominated by syntactic features such as n-grams, the rise of Large Language Models (LLMs) have made this area of research relativley active and interesting. The same line of reasoning can be applied to identification of authors for source codes, which finds considerable applications in the field of digital forensics, plagiarism detection etc. 

Parallel to this line of thinking, it is also possible to rephrase this problem into identifying whether a given piece of text (or code) was generated by a machine or not. This line of reseach has important implications for the field of academic integrity, plagiarism detection, fake news detection and so on. 

Security of web applications and services is of crucial importance in the modern era when much of our transactions is being done online. However, this is by no means easy - given the multitide of attacks that plague us, such as SQL injection, XSS, CSRF, parameter tampering, session violation etc. In addition, there are protocol vulnerabilities, stemming from either weak protocol specifications or vulnerabilities in the implementations. The difficulty in identifying these attacks is due to the fact that a simple rule-based system cannot be used to define these attacks, and often the description of these attacks will simply be "something that normal users wouldn't do". Thus it is necessary to encapsulate what constitutes as legitimate user behaviour, and using this model to identify deviant access to a system. This can be done using simple automata based modelling, scoring mechanisms, or through sophisticated ML/DL models.
