(a) noise will have an impact on VC bound?The answer is no.When noise is added to the signal, it has no intrinsic effect on what we have learned before.Did machine learning really work before? is based on the following: the source of training DataSet D is: (X,f (x)). where x is subordinate to a certain probability distribution p.What impact does noise have on data now? Previously, F (x) was determined. Now f (x) is uncertain. Because the presence of noise affects the value of f (x). At this poin

Object (the instance object of the Class). In short, it's a piece of data in memory that holds the value of an attribute through an instance variable . The use of the object. Create object------Send Message---------Release object (sets the variable that points to the object to nil)Note: The use of objects is not the direct manipulation of the object itself, but the manipulation of pointers to Objects!!! ( For example, the object contained in the array is not the object itself, but a pointer t

Responsive web Design responsive web DesignsThis concept was introduced in May 2010 by famous foreign web designer Ethan Marcotte.

Responsive The concrete practice way is composed of many aspects, including elastic grid and layout, picture, CSS Media query use and so on. Whether the

Code written with a generic mechanism has better security and readability in code that enforces type conversions than those that are cluttered with variables that use the type object.Generic class:The type variable t is placed after the class name, with Generic methods:The generic is placed after the modifier and returns the front of the type.Qualification of generic type variables:Whether a generic type is defined appropriately, a corresponding primitive type erase type variable is automaticall

connected using buffers as bridges, and producers onlyYou need to throw data into the buffer, you can continue to produce the next data, and consumers just need to get the data from the buffer, so that there is no blockage due to the speed of each other's processing.3. Support free and busy unevenIf the speed of manufacturing data is fast and slow, the benefits of the buffer are reflected. When data is made fast, consumptionThe unhandled data can be temporarily present in the buffer. Slow down
