🍸【 春酒之夜｜Cheers 】

期待已久的 BIIC 2026 春酒終於登場啦！上週五BIIC 大家庭難得聚在一起享受一年一度的團聚時刻。謝謝李祈均老師贊助大家參與這場充滿驚喜的春酒饗宴。Biicers在百忙之中抽空交流同樂，真是實驗室幸福的美好回憶˶ˊᵕˋ˵

今年的抽獎流程設計細節滿滿，現場戰況也超級激烈！從基本的藍色入場券到喝酒換來的粉色調酒券，還有金色校友券，層層加碼讓中獎率不斷洗牌。惡魔小獎環節大家都希望不要抽到自己，還有 Kahoot 實驗室小遊戲，第一名竟然可以丟掉別人的抽獎券，補投自己的，真的太刺激了><

最後恭喜所有抱走大獎的幸運兒，沒抽到的也有師母加碼的哈哈獎安慰，BIIC 真的太暖了っ ̫ •̥⸝⸝ 希望大家都玩得開心，我們明年春酒見！🍻

── ✦── ✦ ── ✦ ── ✦ ──

The long-awaited BIIC 2026 Spring Dinner is finally here! Last Friday, the whole BIIC family gathered for our once-a-year reunion, enjoying a rare night to relax and catch up together.

Huge thanks to Prof. Chi-Chun Li for making this amazing and surprise-filled night possible. Taking a break from our busy schedules to hang out like this truly felt special ˶ˊᵕˋ˵

This year’s raffle was next level! Starting from basic blue tickets, to pink cocktail tickets earned from drinks, and even golden alumni tickets—each round kept reshuffling everyone’s chances.

The “devil prize” had everyone praying not to get picked, and the Kahoot game was wild—the winner could literally throw away someone else’s tickets and add to their own. So intense ><

Congrats to all the lucky winners who took home the big prizes! And for those who didn’t, there were still extra “haha prizes” from the professor’s wife—BIIC is seriously too wholesomeっ ̫ •̥⸝⸝ Hope everyone had a great time, see you again next year! 🍻

📑【碩士口試｜Graduate Defense 】

恭喜允彣順利通過口試！

他以「利用多實例學習實現異常呼吸音事件的時間定位」為題，
探討如何在僅具錄音層級標註的情況下，精準辨識異常呼吸音發生的時間位置。

本研究提出一套弱監督多實例學習（MIL）框架，
透過滑動視窗切分音訊，在不依賴昂貴事件標註的前提下，
同時實現錄音分類與時間定位，大幅提升模型的實用性與可擴展性。

此外，研究結合元數據感知嵌入與類別一致性實例混合（CCIM），
有效降低不同錄音設備與臨床環境所帶來的偏差，
提升模型在跨資料集與真實臨床場域中的穩健性與泛化能力。

研究成果為自動化肺部聽診提供一個具成本效益且具解釋力的解決方案，
在臨床輔助診斷與智慧醫療應用上具有重要潛力。

再次恭喜Winson順利完成碩士學位，祝福他迎向人生下一段精彩旅程 ꕀ .* 🎓

──────── ✦ ────────

Congratulations to Yun-Wen on successfully passing the defense!

This thesis, titled “Multiple Instance Learning for Temporal Localization of Abnormal Respiratory Sounds,” explores how to accurately identify when abnormal breathing events occur using only recording-level labels.

The study proposes a weakly supervised Multiple Instance Learning (MIL) framework that segments audio into sliding windows, enabling both recording-level classification and temporal localization without the need for costly event-level annotations—significantly improving practicality and scalability.

In addition, the integration of metadata-aware embeddings and Class-Consistent Instance Mix (CCIM) helps reduce variability caused by different recording devices and clinical conditions, enhancing robustness and generalization across datasets and real-world scenarios.

This work presents a cost-effective and interpretable solution for automated lung auscultation, with strong potential for clinical support and smart healthcare applications.

Congratulations again to Winson on completing his master’s degree and stepping into a new chapter ahead ꕀ .* 🎓

🤖【 智慧質檢｜AI 】

BIIC Lab 很高興與全球人壽展開產學合作，共同推動「AI 智能語音質檢」系統正式上線。此次合作也受到五家媒體報導。系統結合語音辨識與語意分析技術，協助檢查電訪內容是否符合規範，讓服務流程更加透明與可追溯，也讓研究成果真正落地到金融保險場域中。

透過系統化的質檢機制，電訪內容能從過去的抽樣檢查提升到更全面的檢視，也能更快發現異常並啟動後續改善。不僅提升作業效率，也強化整體服務品質與內控流程，讓科技在實務應用中發揮更大的價值。

═══ ◇ BIIC x TG ◇ ═══

BIIC Lab is pleased to collaborate with TransGlobe Life on an industry–academia project to launch an AI-powered voice quality assurance system. The collaboration has also been featured by five media outlets. By combining speech recognition and semantic analysis technologies, the system helps review telemarketing calls for regulatory compliance, making service processes more transparent and traceable while bringing research into real-world financial and insurance applications.

Through a more systematic quality assurance approach, call reviews can move beyond traditional sampling toward broader coverage, allowing potential issues to be identified and addressed more quickly. This not only improves operational efficiency but also strengthens service quality and internal control processes, demonstrating how technology can create real value in practical applications.
