probability matrix
our probability matrix is defined here. https://ogunlao.github.io/blog/2020/07/17/breakingdownctcloss.html#:~:text=This%20becomes%20our,probability%20matrix,%2C

a sequence seq[1:s]seq[1:s]seq[1:s] up to a particular timestep ttt
e.g. "door" and given timesteps T: Up to t = 4. we might be still staying at d. Situation can be like: blank blank blank d

ε”:0, “_“:
Note that simga is for charctor seperation. underscore is for word seperation

only if the tokens on either side of the blank token are different
e.g. door > "d" "blank" "o" == "d" "o" but the skip is permited because "d" and "o" are differnt on the either side of the a blank.

To guarantee that the sequence is an expansion of the target sequence
Now we are creating a grid to get the expanded target sequence.(a.k.a expanded output matrix)

do not include tokens from the target sequence
e.g. the target seqence is "door" if the row doesn't include token "d" "o" "r", we remove it.

key idea
the sum overs paths corresponding to a specific labelling can be broken down into an iterative sum over paths corresponding to prefixes of that labelling.

The total forward loss is the sum of all the probabilities of these paths
We have many different paths to get the same result. loss is computed by taking the sum of the probaiblities of all these paths(th p of they occuring)

model. 3
So far, we already know, given a [X,Y,Z], how do we map it into [u, v].

the kernel
We use the kernel to compare the given pixel with its neighborhood.
