BioPlanner: Automatic Evaluation of LLMs on Protocol Planning in Biology

1 code implementation16 Oct 2023 Odhran O'Donoghue, Aleksandar Shtedritski, John Ginger, Ralph Abboud, Ali Essa Ghareeb, Justin Booth, Samuel G Rodriques

Here we present an automatic evaluation framework for the task of planning experimental protocols, and we introduce BioProt: a dataset of biology protocols with corresponding pseudocode representations.

PlanE: Representation Learning over Planar Graphs

1 code implementation NeurIPS 2023 Radoslav Dimitrov, Zeyang Zhao, Ralph Abboud, İsmail İlkan Ceylan

Graph neural networks are prominent models for representation learning over graphs, where the idea is to iteratively compute representations of nodes of an input graph through a series of transformations in such a way that the learned graph function is isomorphism invariant on graphs, which makes the learned representations graph invariants.

Shortest Path Networks for Graph Property Prediction

1 code implementation2 Jun 2022 Ralph Abboud, Radoslav Dimitrov, İsmail İlkan Ceylan

Most graph neural network models rely on a particular message passing paradigm, where the idea is to iteratively propagate node representations of a graph to each node in the direct neighborhood.

Temporal Knowledge Graph Completion using Box Embeddings

1 code implementation18 Sep 2021 Johannes Messner, Ralph Abboud, İsmail İlkan Ceylan

Temporal knowledge graph completion (TKGC) is an extension of this task to temporal knowledge graphs, where each fact is additionally associated with a time stamp.

The Surprising Power of Graph Neural Networks with Random Node Initialization

1 code implementation2 Oct 2020 Ralph Abboud, İsmail İlkan Ceylan, Martin Grohe, Thomas Lukasiewicz

In this work, we analyze the expressive power of GNNs with RNI, and prove that these models are universal, a first such result for GNNs not relying on computationally demanding higher-order properties.

BoxE: A Box Embedding Model for Knowledge Base Completion

1 code implementation NeurIPS 2020 Ralph Abboud, İsmail İlkan Ceylan, Thomas Lukasiewicz, Tommaso Salvatori

Knowledge base completion (KBC) aims to automatically infer missing facts by exploiting information already present in a knowledge base (KB).
