Abstract:

Machine Learning Meets Genome Assembly 

With the recent advances in DNA sequencing technologies, the study of the genetic composition of living organisms has become more accessible for researchers. Several advances have been achieved due to it, especially in the health sciences. However, many challenges which emerge from sequencing projects complexity remain unsolved. Among them is the task of assembling DNA fragments from previously unsequenced organisms, which is classified as an NP-hard problem, for which no efficient computational solution with reasonable execution time exists. However, several tools that produce approximate solutions have been used with results that, although needing improvement, have facilitated scientific discoveries. As with other NP-hard problems, machine learning algorithms have been one of the approaches used in recent years in an attempt to solve the DNA fragment assembly problem, although still at a low scale. In this talk we present a broad review of pioneering literature comprising artificial intelligence-based DNA assemblers — particularly the ones that use machine learning — to provide an overview of state-of-the-art approaches and to serve as a starting point for further study in this field.
