New KLXX Loss Function Enhances Mode Coverage in Boltzmann Generators

作者 PulseAugur 编辑部 · [1 个来源] ·

研究人员引入了一种新颖的损失函数KLXX，旨在提高归一化流玻尔兹曼生成器的模式覆盖率。该新函数结合了对数比率变化，特别是目标到推向前对数密度比的平均绝对成对差，以提高准确性和探索候选模式。KLXX的Fisher--Rao梯度流表现出非正耗散，数值测试显示与标准的正向KL损失相比，模式覆盖率和诊断准确性得到了提高。 AI

影响 引入了一种新方法来提高玻尔兹曼生成器的准确性和模式覆盖率，有可能增强其在复杂生成任务中的效用。

    arXiv:2609.09473v1 Announce Type: new Abstract: Normalizing flow Boltzmann generators retain a tractable pushforward density, but training with forward KL depends on target samples that may be biased or omit modes. As a result, a flow can miss target mass while its observed impor…
