<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">1996年北京的秋天美轮美奂。我从南方考到北京交通大学信息所读硕士，师从当时的所长袁老师。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">信息所聚焦学术<span style="color: black;">科研</span>：主动视觉，<span style="color: black;">设备</span>人，语音处理，自然语言学习是几个重点<span style="color: black;">科研</span><span style="color: black;">行业</span>。所里博士，博士后<span style="color: black;">亦</span>一大堆。袁老师百忙中和<span style="color: black;">咱们</span>见面，问我线性代数学的怎么样（我说不错），把矩阵论自己补一补，别急着“进实验室上机”。<span style="color: black;">【1】</span></p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">当时人工智能的学术气氛很浓，1997年LSTM<span style="color: black;">亦</span><span style="color: black;">已然</span>发明了<span style="color: black;">【2】</span>。<span style="color: black;">都数</span>硕士<span style="color: black;">朋友</span>还是热衷于更"HOT"的通信(ATM，以太网)和互联网计算机应用软件热潮。很少有人能用神经网络<span style="color: black;">处理</span>现实问题，并且<span style="color: black;">挣钱</span>。人工智能还不是一个<span style="color: black;">公众</span>词汇，我<span style="color: black;">亦</span>和人工智能擦肩而过。<span style="color: black;">【3】</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">我记得我就曾花费<span style="color: black;">海量</span>时间在学校和首都图书馆查阅三维电磁模型定位癫痫病灶算法，帮紫竹院<span style="color: black;">周边</span>一家民营医疗器械<span style="color: black;">机构</span>做<span style="color: black;">开发</span>。（质量<span style="color: black;">欠好</span>，有时候会把病灶定位在脑外）。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">当时的高等教育一个是类似于“证书”<span style="color: black;">或</span>某种“信号”功能，<span style="color: black;">便是</span>你在某某大学硕士毕业<span style="color: black;">能够</span>找份每月发薪水的按部就班的工作。像<span style="color: black;">咱们</span>学校毕业想留北京<span style="color: black;">通常</span>都能有北京户口。还有一个<span style="color: black;">便是</span>当时的互联网和网上教育学术资源还<span style="color: black;">无</span><span style="color: black;">此刻</span>这么发达，高校还主导或垄断<span style="color: black;">有些</span>学术和<span style="color: black;">行业</span>知识技能，无论是师资还是硬件环境，<span style="color: black;">例如</span>设备，图书等等。<span style="color: black;">此刻</span>的高等教育<span style="color: black;">已然</span>走向了新时代的分岔口，<span style="color: black;">再也不</span>主导<span style="color: black;">或</span>垄断学习资源。Bryan Caplan<span style="color: black;">这般</span>问道：“Would you rather have a Princeton diploma without a Princeton
education, or a Princeton education without a Princeton diploma? If you
pause to answer, you must think signaling is pretty important.”</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">十年后的大学<span style="color: black;">亦</span>许与今天非常<span style="color: black;">区别</span>。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><img src="data:image/svg+xml,%3C%3Fxml version=1.0 encoding=UTF-8%3F%3E%3Csvg width=1px height=1px viewBox=0 0 1 1 version=1.1 xmlns=http://www.w3.org/2000/svg xmlns:xlink=http://www.w3.org/1999/xlink%3E%3Ctitle%3E%3C/title%3E%3Cg stroke=none stroke-width=1 fill=none fill-rule=evenodd fill-opacity=0%3E%3Cg transform=translate(-249.000000, -126.000000) fill=%23FFFFFF%3E%3Crect x=249 y=126 width=1 height=1%3E%3C/rect%3E%3C/g%3E%3C/g%3E%3C/svg%3E" style="width: 50%; margin-bottom: 20px;"></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">好吧，回到主题。没想到毕业20年，线性代数，矩阵论穿着人工智能的华贵<span style="color: black;">商场</span>套装，和国家战略契合到<span style="color: black;">一块</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">2. 上市<span style="color: black;">机构</span>业绩暴雷财务一瞥</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">花开两朵，各表一枝。2018年中国A股股市的一大热点<span style="color: black;">便是</span>“业绩暴雷”。上市<span style="color: black;">机构</span>在业务顺利和牛市时粉饰财务报表，在特定情景和时点一次性减记<span style="color: black;">或</span>冲销巨额财产“重新<span style="color: black;">起始</span>”。这些<span style="color: black;">机构</span>有的走在了违法边缘或是<span style="color: black;">已然</span>违法，有的过度<span style="color: black;">运用</span>会计政策的空间迎合市场<span style="color: black;">爱好</span>（<span style="color: black;">例如</span>对成长的追求等等），<span style="color: black;">最后</span>业绩大变脸巨额一次亏个够。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">康得新曾经是一个明星上市<span style="color: black;">机构</span>企业。成长性和股价<span style="color: black;">连续</span><span style="color: black;">报答</span>令人艳羡。我记得当年还曾浏览过这家<span style="color: black;">机构</span>的财报，无奈缺乏起码的行业知识放弃了。2018年康得新<span style="color: black;">已然</span>ST了。当年浓眉大眼的家伙怎么和丑闻和业绩洗澡纠缠在<span style="color: black;">一块</span>了！？</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">媒介</span><span style="color: black;">热榜</span>，康得新账上巨额现金，<span style="color: black;">然则</span>有息负债率<span style="color: black;">亦</span>相当高。<span style="color: black;">倘若</span><span style="color: black;">无</span>其他猫腻，巨额现金和<span style="color: black;">巨额</span>负债只能是一个<span style="color: black;">科研</span>的线索。<span style="color: black;">例如</span>苹果<span style="color: black;">机构</span>现金<span style="color: black;">非常多</span>，<span style="color: black;">然则</span>正在<span style="color: black;">增多</span>有息负债回购股份等等。巴菲特在股东的信里谈到苹果的<span style="color: black;">目的</span>是达到“现金中性”，<span style="color: black;">亦</span><span style="color: black;">便是</span>扣除必要营运资本考量后的净现金为0。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">上表<span style="color: black;">能够</span>看出，康得新<span style="color: black;">连续</span><span style="color: black;">数年</span>高成长的<span style="color: black;">背面</span>，<span style="color: black;">应收账款超出比例的增长</span>，<span style="color: black;">ROE的<span style="color: black;">显著</span>波动</span>都是警示信号。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">由此静安笔记想到，能否应用时下伟大的人工智能技术，<span style="color: black;">经过</span>对上市<span style="color: black;">机构</span>的历史财务数据进行<span style="color: black;">设备</span>学习，大数据预警业绩暴雷<span style="color: black;">或</span>个别上市<span style="color: black;">机构</span><span style="color: black;">反常</span>的财务数据呢!?</p>
