GFlowNets were introduced at NeurIPS in 2021 by Emmanuel Bengio and co-authors. GFlowNets are a deep learning technique for \u201cbuilding objects\u201d at a frequency proportional to the expected reward of those objects in an environment.<\/p>\n

The motivating example in their first paper is the discovery of new chemical structures (or I\u2019ll also refer to them as \u201cmolecules\u201d). Chemical structures, or molecules, are \u201ccompositional\u201d in the sense that they consist of discrete building blocks (atoms). A chemical structure can be tested for a quality of interest, such as antibiotic activity. Some molecules are strong antibiotics \u2014 when tested against bacteria in a laboratory, most bacteria die, and a measurement is obtained that we can think of as a large \u201creward\u201d. Most molecules do not kill bacteria, and so, return a small \u201creward\u201d value from a lab test.<\/p>\n
