I have a friend with a net worth of several hundred million dollars.
Once at a party, somebody suggested to him that he should replace his Timex watch with a Rolex so he would “look rich”. He said, “ I am rich.”
He drives a very nice, well-maintained, several-year-old Volvo, though, and he gives several million dollars to charity each year.
One time he announced a million dollar gift to a charity at their annual fund raising ball. He didn’t tell anybody in advance, just went up to the mic. It really buoyed the spirits of the people who were committed to the cause. Kind of jump-started future donations.
His entire net worth is destined to charity at his death.
Pretty much upper class, I’d say.
Europe has been expensive for NetJets – far more expensive than I anticipated – but it is essential to building a flight operation that will forever be in a class by itself. Our U.S. owners already want a quality service wherever they travel and their wish for flight hours abroad is certain to grow dramatically in the decades ahead. Last year, U.S. owners made 2,003 flights in Europe, up 22% from the previous year and 137% from 2000. Just as important, our European owners made 1,067 flights in the U.S., up 65% from 2003 and 239% from 2000.
To the Shareholders of Berkshire Hathaway Inc.:
Our decrease in net worth during 2008 was $11.5 billion, which reduced the per-share book value of both our Class A and Class B stock by 9.6%. Over the last 44 years (that is, since present management took over) book value has grown from $19 to $70,530, a rate of 20.3% compounded annually.*
To the Shareholders of Berkshire Hathaway Inc.:
Our gain in net worth during 2000 was $3.96 billion, which increased the per-share book value of both our Class A and Class B stock by 6.5%. Over the last 36 years (that is, since present management took over) per- share book value has grown from $19 to $40,442, a gain of 23.6% compounded annually.∗
Overall, we had a decent year, our book-value gain having outpaced the performance of the S&P 500. And, though this judgment is necessarily subjective, we believe Berkshire’s gain in per-share intrinsic value moderately exceeded its gain in book value. (Intrinsic value, as well as other key investment and accounting terms and concepts, are explained in our Owner’s Manual>
Csharp 对xml的支持，那是一等一的友好。很多人不用CSharp，所以不知道。但其实微软耕耘了多年。对企业级应用喜欢的XML，支持的非常到位。举个例子，我们知道序列化，在Java下面不是很好搞，第三方类库很多。官方也不内置一个。
微软官方为.net内置了丰富的XML 类库，你可以把数据从class，转换成为XML文件。
生成的XML文件，其实可读性要比JSON好太多。跟HTML 非常接近，
在eXtended DER-verse中的类增量持续学习
人类智能的主要特征是能够不断地获取知识。与此形成鲜明对比的是，深层网络的遗忘是灾难性的，因此，类增量持续学习的子领域支持的方法是逐步学习一连串的任务，将连续获得的知识融合到一个综合预测中。 这项工作旨在评估和克服我们之前提出的 "黑暗经验重放"（DER）的缺陷，这是一种简单而有效的方法，结合了预演和知识提炼。受我们的大脑不断重写过去的回忆并设定对未来的期望的启发，我们赋予我们的模型以下能力：i）修改它的重放记忆，以迎接有关过去数据的新信息；ii）为学习尚未见过的类别铺路。 我们表明，这些策略的应用导致了显著的改进；事实上，所产生的方法--被称为eXtended-DER（X-DER）--在标准基准（如CIFAR-100和miniImagenet）和这里介绍的一个新的基准上都优于现有的技术水平。为了获得更好的理解，我们进一步提供了广泛的消减研究，以证实和扩展我们以前的研究结果（例如，在持续学习设置中的KnowledgeDistillation和更平坦的minima的价值）。

PPCD-GAN：用于大规模条件性GANs压缩的渐进式修剪和类意识蒸馏法
我们通过利用大规模条件生成对抗网络（GANs）压缩这一新颖的挑战任务来推动神经网络压缩研究。为此，我们通过引入渐进修剪残余块（PP-Res）和经典意识蒸馏法，提出了一种逐渐缩小的GAN（PPCD-GAN）。PP-Res是传统残差块的扩展，每个卷积层后面都有一个可学习的掩膜层，随着训练的进行逐步修剪网络参数。另一方面，class-aware distillation通过指导性的注意力图将巨大的知识从训练有素的教师模型中转移出来，从而增强了训练的稳定性。我们在一个著名的GAN架构上以端到端方式同时训练剪枝和蒸馏过程。训练结束后，所有多余的参数和掩码层都被丢弃，产生了一个更轻的网络，同时保留了性能。我们全面展示了在ImageNet 128x128数据集上，PPCD-GAN比最先进的技术减少了5.2倍（81%）参数，同时保持了更好的性能。
