Understanding Random Walks and Their Applications

The talk explores the concept of random walks and their applications in various fields, including biology, finance, and language. It begins with an introduction to Ronald Ross's work on malaria and the development of mathematical models for disease control. The speaker discusses the emergence of random walks in mathematics, their applications in finance and physics, and the development of Markov chains. The talk also covers the use of Markov models in language processing and artificial text generation, highlighting their role in Google's PageRank algorithm. The session concludes with a discussion on AI and machine learning.
