How does the AI handle text within the images, such as street signs or license plates?

While the AI might not be particularly good at reading text, it does take into account the structure, colors, and shapes of text and signs within the images.

What is the AI's strategy for guessing locations within a country, such as different regions of Canada?

The AI seems to focus on specific details like the type of road signs and the environment to make an educated guess about the location within a country.

What is the AI's performance like when it comes to guessing less common locations or countries that are harder to distinguish?

The AI still performs well, but there are instances where it makes mistakes, especially in regions that are challenging for human players as well, like Cambodia.

How does the human player plan to compete against the AI in the game?

The human player plans to try and make it to the later rounds of the game, hoping to use good multi-off rounds to their advantage and capitalize on any mistakes the AI might make.

What is the potential application of the AI's guessing methodology for human players?

The AI's guessing methodology could potentially be used by human players to learn and improve their own strategies by understanding what the AI focuses on to make its guesses.

What does the future hold for the AI developed by the Stanford students?

While the students believe they have created one of the best AI models for GeoGuesser, they are considering writing a paper on their work and are open to the idea of further improvements and challenges.
