Principle analysis of TLD target tracking

Fern are judged, multiple posteriori probabilities are given. It's like we let a lot of people make decisions, see if this thing is a positive sample, and each person corresponds to a fern. Finally we calculate the posterior mean of this series of fern output to see if it is greater than the threshold value, and ultimately determine whether it is a positive sample. The author skillfully combines the idea of random forest with Orb thought to form its own classifier.

The proof of the whole permutation algorithm generated by the dictionary order method

string is an ordered string from small to large."123456789"and the largest string is the ordered string from large to small" *987654321”。 This is for the123456789all permutations, sorting them out, that you can get an ordered set of all permutations sorted by dictionary order. So, when we know the current arrangement, to get the next permutation, we can range the next number in the ordered collection (just bigger than him). For example, the current arrangement is "123456879"And then the next ar

InnoDB UTF8 Character Set varchar index length problem in MySQL

The limit for total index length is: The InnoDB internal maximum key length is 3500 bytes, but MySQL itself restricts this to 3072. (1024 bytes for non-64-bit builds before MySQL 5.0.17, and for all builds before 5.0.15.) In the UTF8 character set, the [data portion] of varchar (255) occupies 255*3=765 bytes, the closest 767bytes, 256*3 = 768bytes, already over 767.

Required to query the quotation information of the latest day of the corresponding child type in a certain region, if you place the quotation information and date of the last day of all child types in a certain type of region in the temporary table, and then query the corresponding latest date in the History Table, timeout will appear: Make the following
