Generative modeling has undergone a transformative journey in recent times, thanks to the emergence of powerful neural networks. These networks possess an unprecedented ability to capture intricate relationships among diverse variables, revolutionizing our capacity to create coherent models for high-resolution images and complex data. This shift is attributed to the art of decomposing joint distributions […]
We all love our new best friend – the large language model. However, this friendship can be a costly one due to the high price of inferences. A novel architecture proposed by Sun et al. holds promise to optimize the return the investment. Retentive Networks (RetNet – https://arxiv.org/pdf/2307.08621.pdf) is a pioneering architecture that combines recurrence […]
Introduction In the realm of pharmaceutical research, the quest to unlock groundbreaking insights often requires navigating through a vast sea of diverse data modalities. Imagine a powerful tool that can seamlessly process and integrate information from text, images, audio, 3D point clouds, video, graphs, and more, transcending the limitations of conventional AI approaches. Enter “Meta-Transformer: […]
In a new paper, researchers at IBM Research recently presented a novel approach to retrosynthesis. In chemical synthesis, the retrosynthesis problem involves determining the optimal sequence of steps to synthesize a given molecule starting from readily available building blocks, known as precursors. In retrosynthesis, a chemist or computational model must first identify a suitable disconnection […]
Molecular docking is a critical task in drug design, as it involves predicting the binding structure of a small molecule ligand to a protein. Traditional methods for molecular docking rely on search-based algorithms and scoring functions to estimate the correctness of a proposed structure. However, these methods can be slow and inaccurate, especially for high-throughput […]
RFDiffusion is a new method for protein design that leverages the power of denoising diffusion probabilistic models (DDPMs) to generate protein sequences and protein structures. This approach represents a significant advance in the field of protein design, as it allows for the design of complex protein architectures and functions from simple molecular specifications. Figure 1: RFDiffusion […]
Molecular docking tools are commonly used in drug discovery to computationally identify new molecules through virtual screening. However, these tools often suffer from inaccurate scoring functions that can vary in performance across different proteins. To address this issue, researchers at Brigham Young University have developed MILCDock, a machine learning consensus docking tool that uses predictions from […]
I thoroughly enjoyed meeting Andreas Bender at the recent BioTechX conference in Basel. He gave a very honest and thought-provoking presentation on a series of papers released in Drug Discovery Today, titled: Artificial intelligence in drug discovery: what is realistic, what are illusions? Let’s recap his main findings: Artificial intelligence (AI) has had a profound impact on many areas […]
In the past two months, DALL·E 2 has taken over the internet. From Bart Simpson edited into Egyptian art to Donald Trump as the Lorax, text-to-image AI produces amazing results. Caption: “Panda weaving a basket made of cyclohexane”, DALL·E 2 Are these an impressive-but-gimmicky party trick? Or can these innovations be harnessed for applications in scientific domains? Many […]
