Python Machine Learning Theory and Practice (4) Logistic regression and python Learning Theory From this section, I started to go to "regular" machine learning. The reason is "regular" because it starts to establish a value function (cost function) and then optimizes the value function to obtain the weight, then test and verify. This entire process is an essential part of machine learning. The topic to lear

Category (category) is not only a mathematical language, but also a philosophical point of view. The essence of algebraic thought is: abstract, but concise. The generalization is very high. 0. Preliminary concept: morphism, the most common example of such a process is a function or mapping that maintains a structure in a sense. In set theory, for example, the state ejection is a function, in group theory, t

Relational Database Standardization Theory functional dependency and paradigm theory the relational model can be formally represented as R (U, D, dom, F); U: Attribute Set, D: indicates the attribute domain, dom: ing set of attributes like domains. F: indicates the dependency set of data between attributes. 1. function dependencies are defined as follows: assume that the relational mode R (U), X, and Y are

have disks, and in many systems, one disk saves files for many users at the same time. Allocating disk space and documenting who is using which disk block is a typical task for operating system resource management. The combination of these two approaches is a multi-channel technique.The biggest problem with spatial multiplexing is that memory must be split between programs, which needs to be implemented at the hardware level and controlled by the operating system. If the memory is not split, on

(Learning for most of the month, hurriedly put something in the head to pour a little bit out, otherwise forget.) See other people's PPT is logical, one go, see how much I can tell how many things)1 Queue theoryQueues are ubiquitous in life, such as queuing up for tickets, queuing for meals, waiting in line for subways and so on. That will be such a queue abstraction, can be summed up in the 3 to: the total number of queues can be accommodated (for example, the canteen space is only so large, t

Relationship Pattern Design Theory and Pattern Design Theory Normalization: A low-level paradigm can be transformed into a relational model of several advanced paradigms through Mode Decomposition, that is, normalization. Paradigm: Currently, relational databases have six paradigms. The most common ones are the first and third paradigms. The higher the standard, the smaller the data redundancy. First parad

game theory (i): Nim Games Key conclusion: For a Nim game situation (A1,a2,..., an), it is p-position when and only A1^a2^...^an=0, where ^ represents a bitwise XOR or (XOR) operation. Nim game is one of the most classic models in game theory. , it has a very simple rule and a very beautiful conclusion, from the game began to understand the game theory is probab

[SignalR Learning Series] 1. SignalR theory introduction, signalr TheoryWhat is SignalR? ASP. NET SignalR is a development library that allows ASP. NET developers to easily add instant messaging functions to their programs. The instant messaging function can send data directly from the server to the online client without waiting for the client to request data to return data. SignalR provides a simple api to create remote engineering call protocol (RPC

. This is why humans love flowers. This is also the root cause of making flowers a messenger of love. In fact, not only is the beauty of flowers because of the sexual needs of humans (specifically, it should be the needs of reproduction), including the evaluation of beauty. Women with big breasts and big buttocks are considered to be better able to give birth and nurture future generations. So it was later called beauty. That is, the intention of a beauty is to be good at raising future generati

Ancient naive theory People in the ancient age were over years old. Why?Because they adapt to the laws of natural changes in the world, understand the number of skills, have a certain degree of diet restraint, work and rest have a certain degree of Convention, do not over labor. People who understand the principles of health care in the old age often teach people what?In such a case, we should avoid the attacks against the attackers and thieves in a
