aria_context: Create graph to track computations
In krzjoa/aria: Extensible Autodifferentiation

Description Usage Value

TODO: check, if all the operations still exists Thera are several potential solutions of this problem TODO: variable names convention TODO: context enironment should keep exact pointers to all the dlr objects For example, if we create in global x <- tensor(1:100, c(2, 50)) We create pointer to this object, which should prevent object removal. We should do exactly the same in the case of local variables However, there are still two main problems to solve: * how to handle object assignmnet (like this y <- x) * duplicated funs in the environmnet: we don't need hundreads copies of power function etc. Possible solution: duplicated register: object register vs ops register (?)
