What pictures does email evoke? What happens when you hit the "Send" button? Write down everything that comes to mind. Can we find the things that don't make sense? How hard it is to get the data for your models.

If you're looking to transform data, you may do it in a variety of ways, from altering the way the data is displayed to combining data from a variety of sources. Do you believe this to be the case?

You are creating a learning system for estimating the quality of a product based on written reviews. You train the system by looking at databases of reviews that include numerical ratings.

When you test your system, it has extremely poor results. What are some factors which may be influencing this?

Do you have any strong opinions on email? How does data go from one place to another, and where exactly does it go? Make a rundown of all your newfound knowledge. To start things off, why do we classify things in the first place? Compare the information densities of various models (or levels of abstraction).

If you could provide us with a rough idea of the entire quantity of information that goes into making the big picture, that would be much appreciated. Is it possible for a young person to travel the world without running the risk of becoming bankrupt as a consequence of their experiences?

What do you think of when you hear "email"? What happens to a delivered email? List anything new you've learned. I want to know what caused these differences. Does your organization adjust model complexity?

If you want your data to be more comprehensible, you should report it and then talk about the many sorts of visualizations used in scientific papers. Please include supporting evidence for your response, such as instances of when you've used each kind of picture.
