    Hugging Face Inference Endpoints、Jobs 与 Buckets 如何支撑 Papers with Code 搜索

    Hugging Face 用 Jobs、Buckets 和 Inference Endpoints 为 Papers with Code 搭建搜索:离线用 Qwen/Qwen3-Embedding-0.6B(固定 revision、256 维 L2 归一化向量)批量生成论文向量,在线仅把查询嵌入放在请求路径上,端点冷启动或异常时立即回退全文检索。5000 篇论文试点中,L4 GPU 上以 1024 维约每秒编码 75 篇,同一批次可确定性降到 512 和 256 维复用。

    Hugging Face 研究:语音识别模型存在基准优化行为

    Hugging Face 发布研究,用共识分歧、掩码实体检索和拼写切换三类探针测试语音识别模型,发现部分模型会依据声学线索识别基准来源并复现参考文本中的错误。在 VoxPopuli 上,方法标记出约 40% 测试片段可能存在参考错误,涉及约 3% 的参考词;表现基准优化的模型有 18–30% 的概率复现错误参考文本,且 WER 最低的模型反而最容易复现这些错误。在 LibriSpeech 上,部分强模型在数字被静音后仍有约 30–40% 的样本还原出被掩码的数字,拼写切换探针中多个模型超过 50% 随机基线,部分达到约 90% 切换准确率。研究建议使用完全留出的评测集,Open ASR Leaderboard 已新增 Benchmark fitting 标签页,相关脚本与未归一化模型输出已在 GitHub 开源。
