times times the weight of those defaulting clients). Modeling shows that as the model becomes more and more complex, the accuracy of discriminating clients is more and more high, but the rate of miscarriage of normal customers increases. (The problem is the partitioning of the data set.) When the original data set is divided into training and test sets, the weights of default customers in the original dataset have been increased.Workaround: First the data set division, and then improve the trai

medical attention in timeExpert introduction: "Dysmenorrhea is divided into pathological dysmenorrhea and physiological dysmenorrhea." Female menstruation mainly by the hypothalamus-pituitary-ovary reproductive axis regulation, menstruation normal or not with the female physiological state is closely related, but unfortunately many girls because do not know the menstrual pain behind may hide the disease that affects fertility, always put dysmenorrhea improper return to matter. Every dysmenorrhe

that such a simple activity would actually fail.I think it is very important to carry out the actual activities and write code is very different, in the virtual world, there are many things can be replaced, or circuitous implementation, but the reality of a lot of things are irreplaceable.Non-substitution causes all nodes to be concatenated, and the entire system will not function as long as any of the nodes are faulty.OK, about the front-end interest group such activities, in fact, a little an

clear and orderly. If there are too many similar colors, the distinction becomes difficult, on the other hand, strong color conflicts will appear messy and unattractive.To ensure better readability and overall usability, colors should not go out of bounds. There should be a color harmony between each other, so that the site will not appear abrupt and unsightly. Whether it is web design or classic art design, attention to color balance has a great impact on the overall appearance. For starters,

conversion is performed between class hierarchies;In the downstream conversion, dynamic_cast has the function of type checking, which is more secure than static_cast.Also note: A should have virtual function, otherwise it will compile error; static_cast does not have this limitation.This isbecause run-time type checking requires run-time type information, this information is stored in the class's virtual function table(With regard to the concept of virtual function tables, in detail #include (i

Remedial direction: The strength is stronger, the weight is relatively high website, the proposal does not carry on the link tr

data is only the quicksand that is analyzed, now it becomes our well-cultivated object. We want to keep the overlay of the sample, and when it represents the matrix, all the reasoning knowledge is generated by it. We are not afraid of it making mistakes, where they make mistakes, and where they stack up, it is a step closer to the real mother. A mature sample, that is, no longer or rarely make

satisfactory, you can choose "Eraser" to erase, and then use the "Zoom pen" processing. Operation Tip: 1. The magnifying pen is best to approach and slightly larger than the size of the eye. 2. Will enlarge the intensity slightly to adjust the big point, achieves the mouse to click once to complete the eye to become big. In this way, the eye be

analysis process. In the process of building a sharing platform, there are several points to note:L Personnel attention mechanism . Because the enterprise operation is different from the Internet, there are certain closed characteristics, not recommended the use of Weibo attention to openness, but should use a friend circle similar "concern-consent" of the friend mechanism, to avoid inappropriate attention to bring about the disclosure of information;L share range control . Because of the parti

one meets your requirements. We recommend that you use IPython Notebook, Rodeo, and Spyder at the beginning. Like a variety of Ides, Python also provides a variety of data visualization libraries, such as Pygal, Bokeh, and Seaborn. Matplotlib is the most essential tool for data visualization. it is a simple and effective numerical drawing class library. All these databases are included in Anaconda, so after downloading them, you can study which tool combinations can better meet your needs. You

, both arm and DSP are in the small-end mode by default, but many of them can change the size of the end mode by setting. At present, many complier are small-end models, but you writeCodeBoth modes should be supported at the same time, and macro should be used for switching. This test should be added to your test plan. This is necessary and will be analyzed below. How to test the core or complier size-end mode. There is a simple way to add the following code (Google, some are simpler) Short

basics of Python, you need to know how it works and what you need for the data Science library. The key points include NumPy, a base class library that provides advanced mathematical computing capabilities, SciPy, a reliable class library focused on tools and algorithms, Sci-kit-learn for machine learning, and pandas, a set of tools to provide operational dataframe functionality. In addition to the class library, it is also necessary to know that Python is not recognized as the best integrated

, and I think the third shift is the top priority of the book. Big data tells us "what" rather than "why", in the big data age, we sometimes don't need to know the reason behind the phenomenon, we just have to let the data speak for themselves and the relationship will shine.The relationship can predict the occurrence of events, the trend of the situation, in short, to predict the future, the book mentions
