Abstract
This hands-on tutorial offers a practical guide to implementing Graph Neural Networks (GNNs) within the scope of Quantitative Structure-Activity Relationship (QSAR) modeling. Readers will be guided through a detailed, step-by-step process of applying a state-of-the-art GNN algorithm for activity predictions. It is anticipated that this practical tutorial will provide readers with sufficient knowledge to apply GNNs to their problems as well as to gain a good intuition of the underlying concepts. Specifically, the first part of this tutorial introduces the basic theory of GNNs for QSAR, including molecular graphs and their transformation in the GNN. The second part translates this theory into practical code, culminating in a working implementation of a QSAR model using a GNN. Basic knowledge of QSAR modeling and basic proficiency in the Python programming language and Keras deep learning framework is required. The code for the implementation detailed in this tutorial is available at https://github.com/akensert/molgraph/.

  • Pretraining has recently greatly promoted the development of natural language processing (NLP)
  • We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
  • We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
  • The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
  • Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
