I had for sometime been thinking of the “delta”-problem ( this is how I dubbed it, dont know if it is a known problem in ML).
It is easier to illustrate it with example. Let say we have the following sequence :
10, 15, 12, 10, 20
later we get :
12, 17, 14, 12, 22
If you look at those 2 sequences they look different, but if you look at the deltas they are the same :
deltas/velocity: 5,-3, -2, 10
so the moral of the story is that if you record the deltas instead of the exact values you can encode
multiple similar sequences with fixed amount of memory.
How would you approach this problem ? Using clever Encoder ? Change in the SDR format, may be make it 2D ? Change in the TM ?
Expect hierarchy to solve this problem !
PS> I can also think of a “scale” problem … so if we talk more abstractly we can call it “Transformation” problem.
