Q: Data has a better idea とはどういう意味ですか?
A: I see. Ugh. It's a little complicated.

The word 'data' is usually plural. However, we sometimes refer to the technological business sector that specializes in using massive quantities of data as 'big data'.

Q: Data Assimilation とはどういう意味ですか?

Data assimilation is the technique whereby observational data are combined with output from a numerical model to produce an optimal estimate of the evolving state of the system.

For example:
You have a computer model.
The model predicts how water travels through the ground.
You run the model and get a prediction.
Next, you get measurements of water flow in the area.
You measure stream flow rate over time.
Finally, you combine the computer model data with the measurements in the stream and use both to make more accurate predictions. This is data assimilation.
You take data from the computer model simulation, combine it with observational data in the field, and make predictions based on both!
Q: Data redundancy とはどういう意味ですか?
