New active learning method tackles complex Boltzmann distributions

Researchers have developed a new Gaussian Process-based acquisition function called AB-SID-iVAR for active learning problems. This method addresses the challenge of learning an unknown function under a self-induced Boltzmann distribution, which is common in computational chemistry but difficult due to the unknown and intractable nature of the target distribution. The proposed approach approximates the Bayesian target distribution without needing to estimate the partition function, making it applicable to both discrete and continuous domains. Experimental results show improvements over existing methods on synthetic benchmarks and real-world tasks in PES modeling and drug discovery. AI
