论文摘要
本说明提出了有关所谓椭圆势引理的新证明和新观点。该结果在在线学习中很重要，尤其是对于线性随机土匪。结果的原始证明，无论多么简短又优雅，对所考虑的潜力类型没有太大的灵活性，我们认为这种新的解释可能对该领域的未来研究感兴趣。
This note proposes a new proof and new perspectives on the so-called Elliptical Potential Lemma. This result is important in online learning, especially for linear stochastic bandits. The original proof of the result, however short and elegant, does not give much flexibility on the type of potentials considered and we believe that this new interpretation can be of interest for future research in this field.
