SVM support Vector Machine
support vectors: refers to the most difficult data points in the training set that are closest to the classification decision surface."Machine": that is, machine machines, is actually an algorithm. In the field of machine learning, some algorithms are often regarded as a machine (or learning machine, predictive function, learning function, etc.).
SVM is a supervised learning method, that is, the category of the known training point, and the corresponding relationship
possible to learn the true error directly, only the training error can be calculated:where [M] = {1,..., m}, starting from predictor H to minimizing LS (h) is called empirical minimization, referred to as ERM. Erm may have been fitted, LS (h) Small does not represent L d,f (h) small.

Hypothesis space and generalization ability. The meaning of generalization ability is also explained above, for the sake of emphasis, here again: generalization ability is a learning method, which is used to measure the performance of the model learned by the learning method throughout the sample space.
This is of course very important, because the data we use to train the model is only a small sample of the sample space, and if we just focus too much on them, there is the so-called "overfitting
function (the square of the difference between the quadratic loss function ); absolute loss function (absolute value of the absolute loss function) and log loss function (logarithmic loss function. The smaller the loss function, the better the model (mark does not consider overfitting ?).
Empirical risk minimization (ERM): minimizes the loss function:

1. Data View and data model data abstraction have three layers: physical layer, logical layer, and view layer. There are two types of data models used in the logic layer: one is the conceptual data model, which is mainly used for database design. It can be understood by general users and is similar to the way people think. Such a model has an entity.

dataset to normalise the data points to centre the mean into the origin, the Gaussian Distribu tion becomes a normal distribution. The term ' normal law ' is used. In my opinion, it's better to just highly the assumption of independence, since the assumption of independence was Mor E fundamental. The Gaussian distribution, is however, only a special situation of this condition. Regarding to the third point, the statement seems a little too absolute, as maximum likelihood estimation does not sta

management security, and its core is data security and management security, that is, how to use a variety of technology, means, tools and management methods to prevent the leakage of intranet data.
The realization of intranet security requires technology and management to complement each other, but whether it is "management first" or "technology first" has been debated. In fact, the problems of management and technology have been talked about for many years. Let's not talk about which should b

1. Non-probability model vs Probability Model
A non-probability model is a model represented by a decision function, and a probability model is a model represented by a conditional probability.
2. loss function (loss fun) VS risk function (cost fun)
The loss function measures the quality of a model's prediction at a time. The risk function measures the quality of a model's prediction at an average value, which is assumed the expected loss of the model under the joint distribution.
The risk

By using a specific function, the linear regression problem is transformed into a classification problem, that is, by using this function, the value of Y is within the range of 0-1.
Expected Risk (real risk)It can be understood as the average loss degree of data or the error degree of "average" when the model function is fixed. The expected risk depends on the loss function and prob
