current black-and-white template is placed anywhere on the entire image, and the sum of the pixels in the white area (that is, the sum of the 50 pixels covered by the white area) is subtracted from any position, and we are given the characteristics of the 50 pixels of the black pixel coverage area. A feature is actually a arithmetic of pixels within a region. The entire area refers to 100 pixels covered in black and white.The first formula and the second one must be the same.# Haar
the other side, and then send block data at a suitable rate. TCP supports an algorithm called "slow start". It observes that the rate at which the new group enters the network speed should be the same as the rate at which the other end returns confirmation. Slow Start adds another window for the sender's TCP: congestion window. When a TCP connection is established with another network, the congestion window is initialized to one packet segment (that is, the size of the packet segment advertised

· Basic selector exercises
The JQuery selector is used to find elements that meet the conditions.
The basic selector is the most commonly used selector in JQuery and the simplest selector. it searches for dom elements by element id, class, and tagName.
1. $ ("# id"): id selector, document. getElementById ("id ");
2. $ ("div"): Element selector document. getElementsByTagName ("div ");
3. $ (". myClass"): class s

can be explicitly controlled by the user. In DM, a transaction ends (normal or abnormal) in the following situations:
(1) When the attribute of a connection is set to automatic submission, each statement is submitted;
(2) When a COMMIT/ROLLBACK statement is encountered, a transaction is committed/rolled back;
(3) When the automatic DDL submission switch of the system is enabled (on by default), the DDL statement and the pre
-10 can do 1000+ depth.Simonyan and Zisserman found some difficulties in training VGG16 and VGG19 (especially the convergence of deep networks). So in order to be easier to train, they reduced the number of layers that needed to update weight (column A and C in Figure 2) to train smaller models.After a smaller network converges, weight is initialized with a smaller network to initialize a deeper network of weight, which is pre-training. This does not
Part 1 BASIC Language
[Chapter 2 variables and basic types]
C ++ built-in types include bool, Char, wchar_t, short, Int, long int, float, double, long double, the C ++ standard defines the minimum number of digits that each built-in type should occupy. The number of digits that each compiler determines depends on. In VC ++ 2008, the number of bytes occupied by each type is: 1,
The results of type checking for different types of objects, respectively, using the two methods I described. The first column of the table shows the objects that we are trying to find their type. Each two column is run typeof variable (variable is the value shown in the first column). All the results in this column are strings. Finally, the third column shows the results of running variable.constructor on the objects contained in the first column. All the results in some columns are objects.

I can write it right .. Question 3: The relationship between m people and friends was given. At first, a person had an infectious disease, and all his friends came back to visit him. Then, the next day, he got ill, all the friends are ill. The next day after the illness, they will be immune and will not be ill again .. Anyone who is ill will visit him .. After how many days, everyone will be ill. Or it will never end. Problem solving process: 1
