The picture shows a matrix with 3 rows and 3 columns. The first row is focus 1, the second row is focus 2, and the third row is Shantae's session. The same applies to the columns.
Because it is titled "Cosine Similarity", I'm assuming there's a vector comparison happening here.
Understanding Cosine Similarity:
But I don't understand what you are actually comparing.
For example, r1c1 would be comparing focus 1 with focus 1. This would make sense if you are comparing an expected result of focus 1 with what Shantae's session delivered regarding focus 1. A value of 1.00 means that there's highest similarity, which means she's on target.
But if that's how to read that matrix, what does r1c2 even mean? Why would you compare focus 1 with focus 2? And more importantly, why does it also show a value of 1.00, which means highest similarity? Focus 1 and focus 2 shouldn't be similar.
Next, what does row 3 and column 3 mean? They are titled "shantae_session". Does that mean, when looking at r1c3 for instance, that we are comparing focus 1 with Shantae's session? But if that's the case, what are we doing at columns 1 and 2?
So, the only way to make sense of it would be to ignore the upper left 2x2 matrix and only look at row 3 and column 3:
r3c1 would be comparing Shantae's session with focus 1, showing a value of 0.00, which means Shantae didn't see the expected result.
r3c2 would be comparing Shantae's session with focus 2, also showing a value of 0.00, which means Shantae didn't see the expected result.
r3c3 would be comparing Shantae's session with Shantae's session, showing a value of 1.00, which is to be expected because Shantae's session matches Shantae's session.
I totally don't get this matrix at all. It looks fancy in a scientific way, but it's not clear what you are actually comparing.
Courtney, can you please explain how to read this?
