健康资讯 美媒：巴西公布中国的”科兴疫苗”实验有效性
美国彭博新闻社官网1月7日报道：在巴西进行的后期试验中，中国科兴生物科技有限公司(China’s Sinovac Biotech Ltd.)开发的实验疫苗，对新冠病毒的有效率为78%。这是迄今为止疫苗效力最明确的结果，此前的数据引发了”混淆和怀疑”(the most definitive result so far>
Only a handful of contemporary computer scientists, such as MIT professor Josh Tenenbaum, are seriously attempting to incorporate this type of self-organization into artifcial intelligence. Tenenbaum and his Colleagues are working on the "virtual baby project" -a system that would come into the world with the ability to self-generate millions of thoughts and images. These internally generated data would then serve as a basis for learning in the rest of the system, without the need to provide any additional extenal data. According to this radical vision, even before birth, the foundations of our core brain circuits arise through self-organization, by bootstrappring themselves from a database generated inside the system. Most of the initial groundwork occurs internally, in the absence of any interaction with the outside world; only the final adjusmernts are left to learning, shaped by the additional data that we receive from our environment.
只有少数几个当代的计算机科学家，例如麻省理工的Josh Tenenbaum教授在认真尝试将这类自组织纳入人工智能。Josh Tenenbaum和他的同事们正在研究“虚拟宝贝项目”---这个项目是能在现实世界中自动产生数百万想法和形象的能力。然后呐，这些内生的数据充当着系统其余部分学习的基础，无须提供任何额外的外部数据。根据这一根本观点，甚至出生前，我们大脑的核心回路就是通过自组织的建立，通过从产生于系统内部的数据库中自我提取而形成的。大部分原始的基础工作 是发生在内部的，没有任何外部世界的参与；只剩下最终的判断需要学习，需要我们从环境中接收到的额外的数据来塑造。
