I cannot recommend strongly enough this video of Minute Physics about Artificial Intelligence (AI), in less than 5 minutes covers the most important concern about the AI and what research are doing to overcome them. The final conclusion is not new; Technology is not scary or dangerous, it is how some humans use it the problem. About the same topic, if you have more curiosity and time, I also recommend a series of post wrote by Tim Urban some time ago. Waitbywhy AI
We live surrounded by smart machines, indeed there are several algorithms to mimic a mind and provide a machine of intelligence. These magic software are applied in many fields, from finance to medicine. In fact, those algorithms are not new, the foundation of several of them were establish in the early 60. However, they are far from being a thinking mind and in fact each one has its own weaknesses that limit them to achieve the complete mimic of a human mind. So, the magic formula has not been written yet. Pedro Domingos talk about all this in his book “The master algorithm“. I strongly recomend the following video were the author makes a brilliant summary about the state-of-the-art in the field and makes an introduction to the master algorithm – the code capable of conceive a real mind. There is no need of any special knowledge to follow the talk and might motivate you to read the book.
Do a chart with two variables to measure the degree of correlation between them, It is probably the most used statistical tools. And like any other analysis, We must be very careful drawing conclusions because it does not always reflect reality. Two variables can be strongly correlated in many ways. For example, the number of libraries in a city is strongly related with the absolute number of crimes. However, that does not mean that libraries encourage crime. This example is very clear, and it sure is easy to find more examples of this kind, but I would like to mention the spurious correlations. These correlations ocurre when two variables with no logical connection have a strong correlation coefficient. For instance, the annual number of PhD in computer science in the United States and annual revenue of Americans arcades. …… In Tyler Vigen’s website you can find more of those correlations and if you are really interest, you can buy his book on the subject, Spurious Correlations.
