‘We are introducing new approaches to make research more reproducible, reusable and reliable,’ Professor De Roure said. ‘Research Objects are self-contained pieces of reproducible research which we will share in the future like papers are shared today.’

Research

Page 1 says that “educators need ways to separate misinformation from genuine knowledge,” and we should be wise consumers of education research to help us “make decisions that guarantee quality instruction.” Looking for the punch line, I continued reading, drawn to riveting passages such as, “Teachers can further strengthen their instruction and protect their students’ valuable time in school by scientifically evaluating claims about teaching methods and recognizing quality research when they see it.” Translation: Good intentions are not enough. Teachers may be misled by educational hucksters. I’ve had those same suspicions myself, but the target population isn’t limited to the teaching profession.
- Progresses by investigating testable problems;
- Yields predictions that could be disproven;
- Is subjected to peer review;
- Allows for criticism and replication by other scientists;
- Is bound by the logic of true experiments.

ai ann entropy future order research

he concept of the "order" of information is important here, as it is not the same as the opposite of disorder. If disorder represents a random sequence of events, then the opposite of disorder should imply "not random." Information is a sequence of data that is meaningful in a process, such as the DNA code of an organism, or the bits in a computer program. Noise, on the other hand, is a random sequence. Neither noise nor information is predictable. Noise is inherently unpredictable, but carries no information. Information, however, is also unpredictable. If we can predict future data from past data, then that future data stops being information. We might consider an alternating pattern ("0101010. . . .") to be orderly, but it carries no information (beyond the first couple of bits).
but we have not achieved a deeper level of order

- Order is information that fits a purpose. The measure of order is the measure of how well the information fits the purpose. In the evolution of life-forms, the purpose is to survive. In an evolutionary algorithm (a computer program that simulates evolution to solve a problem) applied to, say, investing in the stock market, the purpose is to make money. Simply having more information does not necessarily result in a better fit. A superior solution for a purpose may very well involve less data.
- The concept of "complexity" is often used to describe the nature of the information created by an evolutionary process. Complexity is a close fit to the concept of order that I am describing, but is also not sufficient. Sometimes, a deeper order—a better fit to a purpose—is achieved through simplification rather than further increases in complexity.
- Thus improving a solution to a problem—which may increase or decrease complexity—increases order. Now that just leaves the issue of defining the problem. Indeed, the key to an evolution algorithm (and to biological and technological evolution) is exactly this: defining the problem.
