AI Thread Summary
In the context of the paper, "normalized" refers to the process of calculating normalized interruption time (NIT) by dividing each user's viewed length by the original duration of the video. This approach accounts for the variability in how much of the video users actually watch. The discussion clarifies that NIT is not calculated by the sum of interruptions divided by non-interrupted times or total time watched, but rather by the entire duration of the video. The consensus is that normalization helps provide a more accurate metric for playback interruptions relative to the video's length. Understanding this concept is crucial for interpreting the author's findings effectively.

In a paper I'm reading the author keeps using the word "normalized". What does it mean?
We use playback interruption time as our main metric.
However, since the viewed length by a user varies widely,
instead of just measuring total interruption time of each view,
we normalize it by the viewed length, which we call the
normalized interruption time (NIT).

Does it mean dividing the sum of the interuptions by the sum of the non-interrupted times? Or diving it by the total time thus far? Or dividing by the entire time of the video?

It means diving each viewed length by the original duration of the video.
However, you must tell about the exact origin of this paragraph.

Dividing by the entire duration of the video or up to the point watched?

Usually it would mean dividing by the entire duration of the video.
 
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
