Top 5 Graph Neural Network Datasets for Machine Learning

Are you looking for the best graph neural network datasets for your machine learning project? Look no further! In this article, we will introduce you to the top 5 graph neural network datasets that are widely used by researchers and practitioners in the field of machine learning.

But first, let's briefly discuss what graph neural networks are and why they are important.

What are Graph Neural Networks?

Graph neural networks (GNNs) are a type of neural network that can operate on graph-structured data. In other words, they can learn from and make predictions on data that is represented as a graph, where nodes represent entities and edges represent relationships between them.

GNNs have become increasingly popular in recent years due to their ability to handle complex and irregular data structures, such as social networks, biological networks, and recommendation systems. They have been applied to a wide range of tasks, including node classification, link prediction, and graph classification.

Now, let's dive into the top 5 graph neural network datasets for machine learning.

1. Cora

Cora is a citation network dataset that contains scientific papers from different research areas. Each paper is represented as a node in the graph, and edges represent citations between papers. The task is to classify each paper into one of seven categories based on its content.

Cora is a popular dataset for benchmarking graph neural network models, and many state-of-the-art models have been evaluated on it. It is relatively small, with only 2,708 nodes and 5,429 edges, but it is still challenging due to its sparsity and class imbalance.

2. Citeseer

Citeseer is another citation network dataset that is similar to Cora. It contains 3,312 scientific papers from six different research areas, and the task is to classify each paper into one of six categories based on its content.

Citeseer is also a popular benchmark dataset for graph neural network models, and it has been used in many research papers. It is slightly larger than Cora, with 4,732 edges, but it is still relatively small compared to other graph datasets.

3. Reddit

Reddit is a social network dataset that contains posts and comments from the popular online forum Reddit. Each post or comment is represented as a node in the graph, and edges represent replies between them. The task is to classify each post or comment into one of 41 different subreddits based on its content.

Reddit is a challenging dataset for graph neural network models due to its large size (over 230,000 nodes and 11 million edges) and the complexity of the relationships between nodes. However, it is also a valuable dataset for studying social networks and online communities.

4. PPI

PPI (Protein-Protein Interaction) is a biological network dataset that contains interactions between proteins in the human body. Each protein is represented as a node in the graph, and edges represent physical interactions between proteins. The task is to predict whether two proteins interact or not.

PPI is a challenging dataset for graph neural network models due to its size (over 24,000 nodes and 200,000 edges) and the complexity of the relationships between proteins. However, it is also a valuable dataset for studying protein interactions and developing new drugs.

5. Yelp

Yelp is a recommendation system dataset that contains user reviews and ratings for businesses on the Yelp platform. Each user or business is represented as a node in the graph, and edges represent relationships between them (e.g., a user has reviewed a business). The task is to predict the rating that a user would give to a business.

Yelp is a challenging dataset for graph neural network models due to its size (over 2.2 million nodes and 6.6 million edges) and the complexity of the relationships between users and businesses. However, it is also a valuable dataset for studying recommendation systems and developing personalized recommendations.

Conclusion

In conclusion, these are the top 5 graph neural network datasets for machine learning. Each dataset presents unique challenges and opportunities for researchers and practitioners in the field of machine learning. By using these datasets, you can develop and evaluate new graph neural network models that can handle complex and irregular data structures.

We hope that this article has been helpful in introducing you to these datasets and inspiring you to explore the exciting world of graph neural networks. Stay tuned for more articles and updates on gnn.tips, your go-to source for all things related to graph neural networks!
