because it takes a long time to make a principled decision, but because they do not have to make too many decisions, he has designed a set of rules and policies to solve frequent incidents. If a manager needs to make decisions every day and make decisions from time to time, it means he is a lazy and ineffective person. The so-called "boundary condition" refers to the minimum goal of decision-making? What conditions should be met. For important decisions, it is not enough to determine the

believes that the world can be divided into facts, facts can be divided into atomic facts, and atomic facts are composed of objects and things. an atomic fact corresponds to a proposition. true or false when the proposition is consistent with the reality. the true and false propositions cannot be judged. Just like the

initial hypothesis (method)In creating the initial assumptions, you don't need all the facts, just enough to have a good overall understanding of the industry and the problem. At the start of the project, it takes two hours to go through the industry's publications-mainly to absorb some of the flavor of the industry.Structuring the initial assumptions begins with the key drivers that divide the problem into its constituent parts. For example, if corp

In general, it is assumed that technical decisions are based on technical factors such as facts, measurable values, matters to be considered in the application. But the reality is that, such as feeling, opinion, intuition, prejudice, etc., will affect the decision-making or the solution of the problem, these are the factors that people are unavoidable in doing things. Although some people try to deny, control and suppress these irrational factors, the

vector presented,Without realizing its importance, it is obvious that it is invisible, and if you can perceive it, you can also locate the cause of the error. There are two reasons why people miss the opportunity to find a solution to the problem. through the exploration of four fields, the cognition of people's thinking can break through the common logic level, have a broader and deeper horizon, and enter the real face of the world. Clearly visible areas: sensory, information, knowledge, ori

content return 1 The RETE algorithm mainly improves the match processing process by constructing a network to match. Algorithm detailed description RETE Network is divided into two parts,Alpha network and beta Network. As shown (images refer to other sites). (1 ) alpha network: filtering working memory alphamemory (satisfies the collection of this pattern). There are two types of nodes, filtering type Nodes and other conditions that are filtered by the node. (2)bet

the outcome of both sides. In physics, physicists have hardly taken into account the fact that a large number of observational experimental facts have long been accumulated and a fairly mature theory has been established, and if a new idea differs from all existing ideas and is incompatible with all the theories proven in the observed experiments. So whether you learn a new idea from anyone or anywhere, you may be willing to accept it, but you have n

aggregates are the cause and the birth law, the cause and the birth law all has no self-body, is the real phase, the real phase is the empty phase. Empty meaning there are four kinds: (a) empty nonsense, the cause of life, no self-nature, self-reality, after all, is empty, this meaning understandable. (ii) The void, the absence of a coarse phase and the subtle color, the nominal, and all the law. (c) The emptiness and righteousness of the Heart (d). Heart empty is a slightest dye is none, in th

In this article, we use a free Bayesian software called Winbugs, which makes it easy to estimate and compare the likelihood-based multivariable stochastic volatility (SV) model. By fitting the two-variable time series data of the weekly exchange rate, nine multivariate SV models, including Granger causality in volatility, time-varying correlation, heavy-tailed error distribution, additive factor structure and multiplication factor structure, illustrate the idea. The univariate stochastic vo

expressed explicitly and concisely, and the facts, characteristics and relationships related to the entity can be deduced from the corresponding nodal arcs. (2) because the concept-related attributes and links are organized in a corresponding node, so that the concept is easy to visit and learn. (3) Performance problems more intuitive, easier to understand, suitable for knowledge engineers and field experts to communicate. (4) Semantic interpretation

Expert system (RBEs)The expert system is a branch of artificial intelligence that imitates human reasoning, uses exploratory methods for reasoning, and interprets and proves its inference by using terms that humans can understand. Expert systems have many classifications: neural networks, case-based reasoning, and rule-based systems.RBEs consists of three parts: rule base (Knowledge Base), Working Memory (fact base), and inference Engine (inference engine). Their structure is as follows:Figure

is closely related to the Data warehouse and the RDBMS. But it never stood up and claimed it wasn't as simple as it seemed at first. Hadoop interrupted the conversation by claiming it was a data warehouse in the Hadoop field. Hadoop seems to give up the best marketing PR rep, and after a simple conversation, it turns out that Hive and Hadoop are saving the world. The description is fascinating and interesting. But is it true? is somewhat similar. Data Warehouse Building a real Data warehouse

"The speed of light in a vacuum was about 35 miles per hour, and Jeff Dean spent a weekend optimizing basic physics. "--from" facts about Jeff Dean "In fact, the "facts about Jeff Dean", as described in this g+ post, are not true. But it was unusual for him to build a website similar to "The fact about Chuck Norris." This is because Jeff Dean is a software engineer, and software engineers are usually not li

three stages, the first stage is to change ideas into products, the most streamlined products embody the core value, the second stage of further market segmentation, in-depth product focus, the formation of the core product value recognition; The third stage is based on the user base, in-depth understanding of the market and rapid response, expand love and speed, Form a product belief.In the case of high uncertainty of market and demand, we should use the smallest feasible prototype product to

1.sensitivity, also known as recall,true positive rate, means that the predicted positive case is proportional to (true positive) and all facts are positive.2.specificity, also called, true negative rate, meaning is the proportion of case that is predicted to be negative (true negative) and all facts are negative.3.roc (receiver operating characteristic)ROC can be used to evaluate the classification algorit

information? Careful analysis of the characteristics will find, date, personnel, nature, whether the field can be classified, such as the date of the year-month-day level, the staff also have a subordinate relationship, the field and normal work is also two types of work attendance record, and the length of work and overtime is not such a sense. So we generally list the attributes that can be categorized, become dimension tables, and maintain the referential relationship between

Package Diagram 5 Information Package Diagram (Conceptual Model) Information Package diagram: it is the first or highest level of the data model of the data warehouse. Large Most business data is multidimensional, but the traditional data model represents a number larger than three dimensions. It is difficult to argue. The information package diagram simplifies this process and allows users to design Multi-dimensional information package and establish contact with developers and other users. Th
