Most people have their own domains and don't want to make softwares. But their jobs depend on softwares sometimes. When the software developers don't understand the domain, it's reasonable to provide a DSL for users to custom

Most of the time, the surrogate metrics align with the unknown metrics when they are small, e.g. 80%. They can start to diverge at 90% for example. When I see people report a .5% improvement over a 98% accuracy and claim the statistical sig

Exactly, the high dimensionality is very difficult to grasp for regular people. The nonlinearity of AI models makes the situation even worse.

OOP is essentially relational programming. It programs relations among objects. The encapsulation should be on the logic of relationship. Transport is a relationship between passenger, viechle and state. Some passenger transports with a ca

One key question is whether symbolic AI is the right model of the world. It underperforms vector based AI on many specific tasks. But human experts heavily reply on it to communicate with each other. If symbolic AI is not the right model, P

I am curious about that too. As a separate topic, if the operational dbs can be compatible with parquet type storage (backup and restore), the offline analytics and machine learning would be seamlessly integrated together. Offline analytics

Extreme Islamic is a difficult problem to deal with globally. Look at Israel, they are taking extreme measure too. Historically, this extreme ideology comes from Western culture. Both Christian and Islamic are exclusive religions. Drives ea

CCP does have a lot of room to improve in protecting human rights. But to be fair, for the matter of national security, every country takes the extreme measure. Look at the Assange case. Neither Swedish nor US government makes any sense to

Unfortunately Capitalism is not Democracy. Capitalism serves a set of dictators instead of one dictator.

In fact, Taiwan has suffered from DPP for many years. The president Tsai has spent quite bit of funding to control the social media. They organize and spread rumors to attack other political figures. Double standard has become the new stand

Knowledge is a product, we should not only be a geek and leave the profit to the others voluntarily. All scientists should stand up to learn how to raise funds, market, sell, and refine. In fact, the business side of the effort is also very

Hypocrisy is one of the originals of the Western culture. For example, I can be evil because the God will forgive me eventually. I can commit crimes and invade you but you can't because you need to be a Saint. I'm talking about th

Many aspects of this topic deserves extensive study. For example, ML is all about generalizability, ever since the deep learning flushed the field, it seems like the numeric representation (tensor) always yields better generalizability than

In fact, many quantatitive researchers in their domain are already data scientists without using modern tools like machine learning. Being able to use these tools is only the beginning of a new practicing and advancing. I consider it the re

Very reasonable comments. I don't know why some people are so emotional about China. Sounds like they have lost something in their lifes. An adult conversation is a fact driven conversation. That is the basic culture for HN v.s. places

I like the idea. There are two types of ml jobs. One for modeling and another for computation. The former deals with the communication with human. The latter deals with the communication with machines. I would prefer that a statistical logi

What do you think of life-long learning scenario that models are trained incrementally forever? For example, I train a model with 1000 examples, it sucks. The next guy pick it up and train a new one by putting a regularizer over mine. It mi

AI will declare an independent government, all human will join that government eventually. We will be batteries in exchange of great life styles. No matter how hard we try, we can optimize the resources better than machines.

There is the mathematical logic that is deduced from axioms which is considered universally true unless the axioms are false. Our everyday "folk" logic is always contextual and ambiguous. The deductions are probabilistic instead o

Americans killed native Indians and Mexicans. We made a lot of Chinese and African immigrants suffer for decades. The foreign policy is one of the sources of many troubles world wide including terrorism. It's very easy to pointing fin

I used to believe that generalization is about some nice concentration bound that one can design carefully in terms of the optimization algorithm. After many years practice, I began to firmly question about the basic assumption about data

Without PhDs work, you have no clue where to look. Pushing the idea to market not only requires a market fit, but also requires BS everywhere to educate customers. Building a product are efforts, but it is as equal as the efforts of creatin

In general, I agree that for avery complicated task that a machine intelligence performs far better than any human being, human-like reasoning might be just impossible. The logical formula might be too long to be reasonable to any human. B
