더 깊은 질문

How can Legion's approach be combined with other techniques to address challenges with tail labels?

Legion's approach can be complemented by incorporating techniques that excel in handling tail labels, such as ZestXML. By combining Legion's capabilities in improving the performance of Pre-trained Language Models (PTMs) on mid and head labels with ZestXML's proficiency in addressing challenges related to tail labels, a more comprehensive solution can be achieved. This synergistic approach would leverage Legion's strengths in mitigating the impact of long-tailed distributions on PTMs while also benefiting from ZestXML's effectiveness in handling less frequent topics. By integrating these two approaches, recommendation systems can achieve better overall performance across all types of GitHub topics.
