The claim that “tourism has little financial benefits to the local economy in Venice” is debatable and context-dependent. Here's a detailed breakdown addressing both why the claim may be true in some aspects, and why it may be misleadi

Algebra geometry view makes sense to me. Considering ML as a learning to approximate scheme algorithm. Tensor representation is similar to the SDP trick achieving the optimal max-sat approximation. The difference is that DL approximates fro

US was wiser than others because we were able to look at our mistakes and fix them admirably. It's only a weak character who tries to demonize others in exchange for self-comforting. Sadly, I'm seeing more and more people doing th

To be honest, many potential murders sacrifice themselves so much that I can live safely. I really should have thanked them for not killing me.

From the physics point of view, an intelligence is to keep the universe running in the perfect order, no waste of energy to increase the temperature. All accurate predictions align our current states to the future. If we look deep enough, w

If quantum reality is objective, then probabilistic reality is objective. Deterministic probability like Chaos or second law of thermodynamics imply the existence of incomplete information. This type of probabilistic reality might be subjec

Exactly. a+b should be the same as a.add.b A high level programming language should be designed for communication instead of dictating the computations.

In terms of the statistical learning framework, the Bayesian optimal classifiers are NP hard to find under distribution free conditions. The models have rather large confidence intervals to compare with each other. Scientific methods can on

If they don't buy it from the store, they have to make it themselves. Everybody are satisfied in the transaction because they played well on this trivial zero sum game instead of falling into a negative sum swirl. By the way, economic

Supervised learning algorithms assume that the input data are iid of the future. This is not valid in most of the real applications. The observation that we see men more than women in programming does not necessarily generalize to the futur

The fear is that jobs left to humans are those low level ones. Technology divide up the society into elites who control machines and labors who is controlled by machines. And gradually, the elites become less and less until the day we human

Python does have a lot of problems, but it's so far the most flexible language like English. High level programming language is meant to communicate, not to dictate the computation. Python happens to be easy to understand by humans.

Most of human knowledge are represented in logic. Semantic web is designed from description logic. A less powerful logic than first order logic.

It seems odd to me that they ended up computing the average of the word vectors which is way too simple to represent meaning. Similarity metric over this semantic vector is not accurate.

HK has been in a bad economic situation for many years. Without mainland China's support, it's even worse. The tension in the HK society is at the breaking point. Young generation has less opportunities to improve their life quali

I like the Capsule idea too. In some way, capsule network is very similar to sparse attention network. It's just the attention normalization is different. Attention is normalized on the inputs, the capsule is normalized on the output.

I prefer a user driven random walk. Like a multi-arm bandit over a hierarchical graph instead of a stuck-in-local-minimun + noise recommender. But no one does it. Years ago, there is an app stumble upon. I always find it engaging. Hard to g

I am not sure that I get the definition of skill right. Does classifying hot dog or not count as a unique skill or not? Or does object detection count as one skill? Intelligence is hard to measure. It's personal and contextual. Even th

Instead of overfitting , it's more related to exploitation vs exploration. We see more men related to programming might be just that women are not given opportunities to explore the programming as a career. When AI makes a decision, ri

Agree. Most of program languages are context free. Human language is mostly context dependent. The auto completion and auto suggestion are the tools to close the gaps of the user experience. Moreover, human communication is continuous and c

Good comment. A truly ideological person with high moral ground should help instead of blame. Media's double standard is a deal with evil.

This is a less studied senario for time series research: contextual forecasting. With enough contextual information, forecasting doesn't need to squeeze the information from its own history that hard.

Relational algebra didn't evolved into a relational programming language. SQL is merely a query language. The recursion is horribly done and there is no type systems. Imagine this, Friends(a: Person, b: Person) defines the relationship

Patent system was not meant for 21st century. Many drugs re-patented to profit higher, e.g., Albuterol. Innovation should be protected with a capped value instead of a period of time.

Human knowledge is built upon the high level logical relations. For example, 3-body problem. The equations over the variables are always right although no one can predict them accurately using those equations. Current black box AI does not
