Graph Based Machine Learning Interprets Diagnostic Isomer-Selective Ion-Molecule Reactions in Tandem Mass Spectrometry

Here, we introduce a first bootstrapped decision tree model trained on 36 known ion-molecule reactions with MOP using graph-based connectivity of analyte’s functional groups as input. Expand abstract.

Integrating Deep Neural Networks and Symbolic Inference for Organic Reactivity Prediction

Our approach outperforms previous graph-based neural networks by predicting products with more than 90% accuracy, demonstrates intuitive chemical reasoning through a learned attention mechanism, and provides generalizability across various reaction types. Expand abstract.

Policy Synthesis for Factored MDPs with Graph Temporal Logic Specifications

The structure in the model and the specifications enable to develop a distributed algorithm that, given a factored Markov decision process and a graph temporal logic formula, decomposes the synthesis problem into a set of smaller synthesis problems, one for each agent. Expand abstract.

On the enhanced power graph of a group

The enhanced power graph $\mathcal{P}_e(G)$ of a group $G$ is a graph with vertex set $G$ and two vertices are adjacent if they belong to the same cyclic subgroup. Expand abstract.

On $\sigma$-arithmetic graphs of finite groups

Let $G$ be a finite group and $\sigma$ a partition of the set of all? primes $\Bbb{P}$, that is, $\sigma =\{\sigma_i \mid i\in I \}$, where $\Bbb{P}=\bigcup_{i\in I} \sigma_i$ and $\sigma_i\cap \sigma_j= \emptyset $ for all $i\ne j$. Expand abstract.

Coordinated Reasoning for Cross-Lingual Knowledge Graph Alignment

Existing entity alignment methods mainly vary on the choices of encoding the knowledge graph, but they typically use the same decoding method, which independently chooses the local optimal match for each source entity. Expand abstract.

A Construction of Uniquely Colourable Graphs with Equal Colour Class Sizes

A uniquely $k$-colourable graph is a graph with exactly one partition of the vertex set into at most $k$ colour classes. Expand abstract.

A note on purely imaginary independence roots

We show that there are infinitely many connected graphs with purely imaginary independence roots and that every graph is a subgraph of such a graph. Expand abstract.

BlastFrost: Fast querying of 100,000s of bacterial genomes in Bifrost graphs

BlastFrost queries a Bifrost data structure for sequences of interest, and extracts local subgraphs, thereby enabling the efficient identification of the presence or absence of individual genes or single nucleotide sequence variants. Expand abstract.
