Pareto Set Learning (PSL) is efficient in Multi-objective Learning (MOL) to obtain the complete optimal solution.Approach addresses the challenge of making diverse Pareto solutions while maximizing hypervolume value.Proposed method SVH-MOL uses Stein Variational Gradient Descent (SVGD) to approximate entire Pareto set.Method validated through experiments on multi-objective problems and multi-task learning, showing superior performance.
