any complex function, A is any element of Banach algebra B, in fact a^2 is obviously definable, generally, when f is a complex coefficient polynomial, according to B is a linear space on C and the multiplication defined on it, f (a) Definition is also clear, so when F is more complex, we also want to define an F (a).To give a simple example, for an arbitrary A to be B, we use a power series to define the e^a=∑a^n/n!, and to discuss whether the definition is meaningful only needs to discuss whet
length of the cell, the better the approximate degree; the better the approximation, the less it is. Therefore, in order to get the exact value of the area, we only need to subdivide the interval infinitely, so that the length between each cell tends to zero.
If you remember, the length of each cell tends to be 0 of the price.

What are machine learning?The definitions of machine learning is offered. Arthur Samuel described it as: "The field of study that gives computers the ability to learn without being explicitly prog Rammed. " This was an older, informal definition.Tom Mitchell provides a more modern definition: 'a computer program was said to learn from experience E with R Espect to some class of tasks T and performance measure P, if it performance at tasks in T, as measured By P, improves with experience E."Examp
interval.2. Function transformationHorizontal and Vertical transformations:Take y=ƒ (x) as an example:y=ƒ (x) +c, the function moves up the C distance;y=ƒ (x) –C, the function moves downward by a C distance;Y=ƒ (x+c), the function moves to the left of the C distance;Y=ƒ (x–c), the function moves the C distance to the right.Stretching, shrinking, and reflection transformations:Take y=ƒ (x) as an example:y=cƒ (x), the function stretches the C-fold in the vertical direction;y= (

The training data format is as follows:
The input has four dimensions, and the output is {-1, + 1 }. There are a total of 400 data records.
The question requires that the weight vector element be initialized to 0, and then "Naive Cycle" is used to traverse the training s
