Welcome to GraphDot’s documentation!¶
GraphDot is a GPU-accelerated Python library that carries out graph dot product operations to compute graph similarity. Currently, the library implements the Marginalized Graph Kernel algorithm, which uses a random walk process to compare subtree patterns and thus defining a generalized graph convolution process. The library can operate on undirected graphs, either weighted or unweighted, that contain arbitrary nodal and edge labels and attributes. It implements state-of-the-art GPU acceleration algorithms and supports versatile customization through just-in-time code generation and compilation.
- Compares graph with different number of nodes and/or edges.
- Allows user to define arbitrary attributes and custom similarity functions on individual nodes and edges.
- Fast, memory-efficient GPU algorithms for CUDA.
- Compatible with major graph libraries such as NetworkX and graphviz.
- Interoperable with scikit-learn.
- Built-in specialization for chemistry and material science applications.
