在短视频社交平台的隐秘角落，一场基于虚拟合成技术的犯罪正悄然蔓延。记者调查发现，通过AI换 脸、深度伪造等虚拟合成技术，大量违背伦理道德的色情视频被"炮制"而出。受害者面容被恶意嫁接到 各类低俗影片中，甚至滋生出黑灰产。 转自：北京日报客户端 经参调查丨色情视频被恶意"炮制" 几元就能买到预训练模型 警惕AI换脸技术滥用滋生黑灰产 业内人士指出，这些以假乱真的换脸视频不仅突破了法律与道德的底线，更对个人安全和社会公序良俗 构成严重威胁，呼吁加强治理。 小雨是一名娱乐主播，直播内容主要是和粉丝聊天，不涉及任何擦边内容。但不法分子却将小雨的脸换 到色情影片中传播，让她无端卷入不良舆论风波。 "视频是不能P的""居然背着我们偷偷拍片"……看到直播间公屏上类似弹幕如爆炸般袭来，小雨自此不 敢再参加任何线上或线下社交活动。 后来，小雨在短视频平台又看到，有人毫不避讳地宣扬有关她的色情影片。顺着对方给的联系方式，小 雨进入了所谓的"工程设计交流群"，发现群里全是各种各样的网址和行业黑话。在这个群里，不法分子 将许多女性的脸换到色情电影中非法牟利。最终，小雨报警，五名嫌疑人被抓，相关账号和群聊也被永 久封禁。 小雨的遭遇， ...

Core Viewpoint - The article discusses the development of LucaOne, a generalized biological foundation model that can simultaneously understand and process nucleic acids (DNA and RNA) and protein sequences, marking a significant advancement in the field of life sciences [4][26]. Group 1: Introduction to LucaOne - LucaOne is the world's first foundational model capable of unifying the understanding of nucleic acids and protein sequences, likened to a "DeepSeek" for life sciences [4]. - The model was pre-trained on sequences from 169,861 species, showcasing its ability to comprehend key biological principles such as the translation of DNA into proteins [4][16]. Group 2: Technical Aspects of LucaOne - The model utilizes a vocabulary of 39 "characters" to encode nucleotides and amino acids, allowing it to read both nucleic acids and proteins [13]. - It employs semi-supervised learning, integrating known biological annotations to enhance its understanding [14]. - LucaOne has 1.8 billion parameters and has been trained on 36.95 billion biological sequence "words," enabling it to extract deep, universal patterns from nucleic acid and protein sequences [16]. Group 3: Performance and Capabilities - LucaOne demonstrated an impressive ability to understand the central dogma of molecular biology without explicit instruction, outperforming specialized models in tasks involving DNA and protein sequence matching [18]. - The model excels in generating embeddings that accurately capture the biological significance of sequences, outperforming other models in clustering similar sequences [19]. - It has shown strong performance across seven challenging bioinformatics tasks, including species classification and protein stability prediction, often using simpler downstream networks compared to specialized models [20][24]. Group 4: Significance and Future Outlook - LucaOne provides a unified framework for understanding the two core molecular carriers of life, breaking down barriers between different molecular types [26]. - The model exemplifies the potential of foundational models in bioinformatics, allowing researchers to develop various biological computational tools efficiently [26]. - It paves the way for deeper and more automated analysis of complex biological systems, such as gene regulatory networks and disease mechanisms [26].
