data points, which involves the mapping of non-linear data to high-dimensional to achieve the purpose of linear divisible data.Support Vector Concepts: The above sample map is a special two-dimensional situation, of course, the real situation may be many dimensions. Start with a simple understanding of what a support vector is at a low latitude. Can see 3 lines, the middle of the red line to the other two first distance is equal. The red one is

Many friends want to learn machine learning, but suffer from the construction of the environment, here is the Windows Scikit-learn Research and development environment to build steps.Step 1. Installation of PythonPython has versions of 2.x and 3.x, but many good machine learning Python libraries do not support 3.x, so

But in that era, it was a book of epoch-being. The first chapter clearly defines what is ML: essentially, a function is approximated by a given search space and computational resources. 2. The Elements of statistical learningAuthor: Trevor Hastie/robert tibshir
of energy and enthusiasm, I think this is the need to read Bo it.However, for me who just want to be a quiet programmer, in a different perspective, if you want to be a good programmer, in fact, too much of the theory is not needed, more understanding of the implementation of some algorithms may be more beneficial. So, I think this blog is more practical, because it is not in theory to do a big improvement and improve the effect, but a distributed machine

I. Introduction of supervised learningThe supervised machine learning problem is nothing more than "Minimizeyour error while regularizing your parameters", which is to minimize errors while the parameters are being parameterized. The minimization error is to let our model fit our training data, and the rule parameter is to prevent our model from overfitting our training data. What a minimalist philosophy! B

segmentation part (at this point the accuracy also reaches 100%). Then the accuracy of the model reaches 90%. The third step. We use the manual to complete the work of character recognition. Finally the accuracy of the model reached 100%. We get the following table:Analyzing the above table, we found that by upgrading the three steps in pipeline, we were able to add 17%, 1%, 10% respectively to the accuracy of the model. We have reached the upper limit of three steps in advance (the performance
recognition work, the final model of the accuracy reached 100%. We get the following table:Analyzing the above table, we find that by increasing the three steps in pipeline, we can add 17%, 1%, 10% respectively to the accuracy of the model. We have reached the upper limit of three steps in advance (the performance of three steps is optimized to 100%, not better), the resulting three sets of data is also the upper limit, this is the upper limit analysis. As a result, we know that optimization of
the master, you can think of some ideas combining, such as someone using Method 1 to solve problem A, some people use method 2 to solve problem B, then I use Method 2 to improve the method 1 to better solve problem A, this is the point of the paper.⑥ 工欲善其事 its prerequisite. From the paper review and download, document management, note management, data collection and collation, experimental tools, paper writing process and other aspects, more optimization of their own work flow, save time even t
original intention is not distorted, two definitions are given in English format:When the target variable that we'll trying to predict are continuous, we call the learning problem a regression Problem.When y can be on only a small number of discrete values,we call it a classification problem.When we understand the above basic concepts, we formally enter the machine lea

only need to use the sudo apt-get install virt-manager to install the software. The software relies on Libvirt and is automatically installed during the installation process. The effect of running Virt-manager is, note that you must run with sudo because the software requires Superuser privileges:The software automatically identifies whether the virtual machine environment in the system is QEMU+KVM or Xen. Create a new virtual
name. However, this is a standard term that people use in machine learning, so we don't have to worry about why people call it. Summary: when solving the housing price prediction problem, we actually want to "Feed" the training set to our learning algorithm, and then learn a hypothesis H, then we input the size of the house we want to predict into H as t
