[뉴스스페이스=이종화 기자] 펜실베이니아대학교 공과대학 연구진이 역편미분방정식(inverse PDE) 문제를 기존보다 6~10배 적은 메모리와 시간으로 풀어내는 새로운 인공지능(AI) 기법 ‘몰리파이어 레이어(Mollifier Layers)’를 개발했다. phys.org, arxiv.org, tun.com에 따르면, 이 소식이 알려지면서 수학·과학계의 이목이 쏠리고 있다. 이번 연구는 머신러닝 분야 국제 학술지인 《Transactions on Machine Learning Research》에 게재됐으며, 2026년 인공지능 최고 권위 학회 가운데 하나인 NeurIPS 2026에서 발표될 예정이다. 역편미분방정식, ‘연못 물결로 돌 위치 찾기’ 난제 역편미분방정식은 “결과를 보고 원인을 역추적하는” 전형적인 역문제다. 고전적인 편미분방정식(PDE)이 ‘법칙(방정식)과 초기조건을 알 때 미래 상태를 예측’하는 순방향 문제라면, 역편미분방정식은 온도, 압력, 농도, 이미지 등 관측 데이터를 기반으로 그 뒤에 숨겨진 계수, 반응속도, 경계조건을 되짚어내는 작업이다. 연구 책임자인 비벡 쉬노이(Vivek Shenoy) 교수는 이를 두고 “연못의 물결만 보고, 어디에
[News Space=Reporter seungwon lee] Bathroom specialist Daelim Bath (formerly Daelim B&Co, CEO Kang Tae-sik) has completely escaped the sluggish performance of 2023, where it recorded a consolidated net loss of 5.55 billion KRW, by posting 300.6 billion KRW in revenue and 13.5 billion KRW in net profit. However, behind the flashy turnaround figures, the company is still tagged with the lowest investment-grade credit rating (BBB-). With 56.9 billion KRW in short-term borrowings weighing down as current liabilities, its current ratio stands at a mere 105.4%, revealing the limits of its financ
[News Space=Reporter seungwon lee] BR Korea (CEO Do Se-ho), the operator of Baskin Robbins and Dunkin', continues to suffer from a abnormal profit structure, posting operating losses for two consecutive years in 2025.

[News Space=Reporter seungwon lee] While GL&Co (CEO Choi Hyun) saw a temporary return to profit in 2025 with stagnant revenue, the reality behind these figures reveals a crisis of cash depletion, supported by 23.8 billion KRW in short-term borrowings and cash reserves of only 76 million KRW at year-end. Furthermore, despite a 'Qualified Opinion' in the previous year's audit regarding 2.75 billion KRW in receivables from related parties, the loss allowance for this debt remains unchanged. This raises serious doubts about internal controls and the transparency of fund management. GL&Co’s
[News Space=Reporter seungwon lee] Global Sae-A Co., Ltd. (CEO Kim Ki-myung) reported 2025 operating revenue of 179 billion KRW, a 47.9% increase from the previous year. Operating profit surged by 101.1% to 133 billion KRW, and net profit skyrocketed by 128.3% to 107.5 billion KRW. However, behind these figures, a serious crack in the company's financial structure is hidden. While 88.1% of operating revenue comes from 'paper profits' (equity method gains), actual cash flow from operating activities worsened to -23.2 billion KRW. With short-term borrowings surging by 52.5% and the current ratio
