These versatile models are pre-trained on vast datasets such as biological sequences, protein structures, single-cell transcriptomics, biomedical images, and text. This extensive pretraining allows FMs to achieve general learning goals, enabling them to be fine-tuned for specific applications like disease detection, drug design, and the discovery of novel therapies without reinitializing their parameters. This adaptability has positioned FMs as state-of-the-art tools across various AI-driven domains.
Building effective foundation models requires sophisticated architectures like transformers, convolutional neural networks (CNNs), graph neural networks (GNNs), and more importantly, high-quality training datasets. These datasets must be diverse, well-curated, and annotated to capture the complexity of biological systems. The models' ability to generalize across multiple downstream tasks depends heavily on the quality and scale of these datasets. For instance, FMs trained on noisy or incomplete data may struggle to provide reliable insights or require extensive customization to function effectively. (1)
Creating AI-ready datasets is therefore an important factor influencing the success of foundation models. Ensuring that the data is clean, consistent, and representative of the biological diversity at hand is crucial to making FMs work efficiently. This blog delves into the importance of such datasets, discussing challenges in their preparation and offering solutions to overcome them for seamless integration with foundation models.
