Top 10 DataHours – An Overview

Analytics Vidhya is one of India’s largest communities for Data Science, Machine Learning, and Analytics. We have always kept our community at the centre stage of the ecosystem. From blogs and practice problems to courses and hackathons, our community has been actively engaged with us throughout the years to share and disseminate knowledge in the data science domain.

Keeping the community in mind, at the beginning of 2022, Analytics Vidhya initiated a one-hour webinar series called: “DataHour’.” We have completed over 170 sessions, and more than 17,000 attendees have leveraged the sessions. The top industry leaders conduct these sessions, covering domains ranging from AI, Blockchain, Career-oriented guidance, Data Science, Data Visualization, ML, NFT, NLP, etc.

While we are on the edge of entering a new year, it’s about time that we reflect on the top 10 DataHours of 2022 based on the popularity of the Datahour among viewers.
