Small data in the big Data age

What is small data? Small data is the individual data, the digital information of each individual. For example, I drink one or two wine every day, suddenly one day after drinking stomach pain, I think, this day and before what is different? It turns out that this day's drink is a new brand. This is the "little data" of my life, it's not as vast as the big data, but it's important to me.

The first to realise the importance of "small data" is Depohal Ais Austin, a professor at Cornell University in the United States. Esting's father died last year, and a few months before his father's death, the computer science professor noticed a slight difference in the social pulse of the old man-he stopped sending emails and not http://www.aliyun.com/zixun/aggregation/ 38323.html "> Supermarket to buy vegetables, to walk around the distance is also getting shorter."

However, this gradually weakened state, to the hospital to check the electrocardiogram, but not necessarily can be seen, whether it is to test the pulse or check the medical records, the 90-year-old did not show a particularly obvious abnormalities. But in fact, tracking his personal data every moment of the day, his life is clearly different from before. This warning and insight into the life messages of this daily little data has inspired the professor of computer science-small data can be seen as a new medical evidence, which is "your row of misspelling data" (the line in their data that belongs to you).

If you are a patient, a small, individualized data may help you answer: what dose should I use every time I take a pill? Of course, there will be a medication instruction on the drug manual, but that number is based on statistical analysis of massive numbers of patients, and is it suitable for you at this moment So you need to know about your own "little data".

Another example is cancer therapy. The same tumor cell DNA causes different patients different changes, so the treatment can not only be "the right remedy", but also "drug". These individualized therapies need to record and analyze the regularity of individual behavior over time, which is the meaning of small data.
