Introducing Seep.jl, a tensorflow like library for julia, available at https://github.com/mit-ll/Seep.jl.
I wrote this package over the last year to learn about modern neural network architectures. It still immature and there are many areas that need improvement, but I’ve decided to publish it now because it has a foundation and many of the pieces that are needed to train neural network models. We have been able to use it to reproduce recently published results and experiment with adapting techniques to our problems.
Seep builds and evaluates computational flow graphs in julia. A computational flow graph (CFG) is a directed acyclic graph where nodes represent values and edges represent data dependencies. It is similar to the Single Static Assignment form of a program used by compilers, but there is no control flow. All nodes are evaluated each time the graph is executed.
The CFG is first defined as an abstract graph using ANodes. The abstract graph specifies the size and shape of each variable, how they are connected, and how each value will be computed. It does not allocate storage or define the order of operations.
One or more instances of may be constructed from the abstract graph. Each instance is a julia function that evaluates the CFG described by the abstract graph. Storage for the values of each ANode is allocated statically when the instance is constructed. In addition to being callable as a function, the instance provides access to the Arrays on which it operates.
All feedback is welcome. Please let me know if you find it useful or interesting.
