Welcome to our Scientific and Practical Conference:  "Challenges and innovations in property valuation through AVMs for a transparent market in a Transforming World"

Throughout this event, our focus will be on elucidating AVM, addressing ethical considerations, evaluating its current state, and envisioning future prospects in valuation. The discussions will extend to practical applications across diverse markets, unraveling the algorithms behind the scenes, scrutinizing data sources and requisite data structures, and emphasizing data security and protection.

Our attention will then turn to advanced algorithms and modules in AVM, dissecting both their potential and limitations. Delving into the captivating realm of human-machine fusion in AVM, we will explore the synergies between human minds and machines in mass appraisal scenarios.

The conference will conclude by exploring the future of AVM, highlighting emerging trends and innovations in this dynamic field. Our overarching goal has been to nurture thought-provoking discussions and establish a dedicated platform for the exchange of knowledge, experiences, and groundbreaking advancements, all centered around the challenges and innovations in property valuation through AVMs for a transparent market in a transforming world. We aim to leave our participants enriched with a deeper understanding of the evolving landscape and the pivotal role AVMs play in shaping the future of real estate markets, fostering transparency, and adapting to the dynamic needs of our changing world.
