Moreover, the numerical speed tasks were strongly correlated with verbal and figural reasoning. This indicates that in this sample the basic numerical skills were not overlearned in many cases, changing the character of the tasks from perceptual speed to reasoning tasks.

Modeling of Artificial Intelligence

From this view, the demonstrated problems are owing to a great extent to the limited area of validity of this test. The BIS-4 Test was originally developed for persons with medium to higher education level. It is necessary to adapt many tasks before the test is given to broader samples.

Nevertheless, it is an illusion that the variance components can be balanced completely as the model suggests.

In so far, there will always be a disjunction between theory and empirical results. Guttman originally introduced a facet referring to the level of complexity of tests.

Guttman predicted that complex tests would be located at the periphery of the radex because complex tests would have fewer components in common with each other than simple tests as they diverge in different directions of complexity. The most complex tasks of the BIS are probably the reasoning tasks, the simplest tasks are surely the speed tasks.

However, the "g" loadings of the operation factors in Figure 4 and the "g" loadings of the cells in Figure 5 are rather similar. Thus, the present results do not support Guttman's complexity facet. The analyses presented here also point to the fact that there are different ways to represent faceted hierarchical models within confirmatory factor analysis. On the one hand, identification problems occur when a "g"-factor is modeled at the top of the hierarchy together with operation and content factors loading on "g".

These identification issues could be solved by means of an equality constraint on two loadings of operation factors on "g". This was only a slight modification, but this equality constraint is not part of the BIS. Another aspect of this model that is not explicitly part of the BIS is that "g" has only indirect effects on intellectual performance through the content and operation factors.

In order to allow for direct effects of "g" on performance, a nested factor model was investigated. In this model the variances of the cells are decomposed into the variances represented by orthogonal content factors, operation factors, and "g". This type of modeling has greater emphasis on the first BIS assumption all intellectual abilities contribute to every intellectual performance, but with different weights because the loading of the cells on "g" represent the common variances that are represented by the cells, but not by the specific content and operation factor of the cell.

However, these analyses revealed that the amount of performance variance directly explained by "g" is not substantially larger than the amount of performance variance that is indirectly explained by "g" through the content and operation factors. One can therefore conclude that there is no relevant "g"-variance that is directly related to the task and that nearly all the "g" -variance in the performance variables is indirect. From a more general point of view it should be noted that it is impossible to represent the hierarchical relation between "g" and the operation and content factors third BIS assumption and the second assumption intellectual abilities contribute to every intellectual performance with different weights simultaneously within a single CFA model.

This indicates that the large number of parameters to be estimated limits the flexibility of the representation of faceted models by means of CFA models. In spite of these limitations, the BIS provides a useful framework in intelligence assessment. This classification can be used for assembling a test battery but need to be validated firstly. Two aspects are of critical importance for assembling a test battery for the BIS: 1 the balance of the content of every operational construct.

We recommend at least three tasks verbal, numerical, figural for each BIS cell. In our view, it is more important to use several independent measures with limited reliability than only one task with strong reliability. The first option strengthens the validity because test takers need to prove their intelligence in different situations. The second option again strengthens the task reliability under the risk that task specific variance is dominating the ability score; 2 In order to measure "g" and the content-related abilities, a full test battery including tasks for every of the twelve tests is needed.

Moreover, it would be an improvement to provide unspeeded measures of reasoning, but this would require additional testing time. Beauducel, A.

Structural Equation Modeling. Integrated Model. With this system, it is possible to quickly make calculations for analyses and reporting, two important elements in the decision-making process. The system has access to centralised business data which it rapidly analyses. The insights formed here are used in the decision-making process. Think of bank employees who analyse what the online banking behaviour of their customers looks like.

OLAP first requests data from the bank accounts of all customers, analyses user activity, and then presents the insights in a uncomplicated way. The software needs to access a lot of data, centralised or decentralised, for the use described above. Data comes in different shapes and sizes. Some data comes from systems, other comes from a database that was managed by a certain department, etc. It often concerns automatically generated reports, or manually kept lists in Excel. Business Intelligence BI is often considered to be more difficult than it really is.

Naturally, the collecting and processing of business or market sensitive information is a delicate process, but it becomes easier with the six-step roadmap from the Business Intelligence Model BIM. The first step is collecting the data and connecting them to the Business Intelligence BI system.

A Model for the Life of an Artificial Intelligence. As the technology matures we need to start thinking about how our understanding of the software engineering aspects of it need to mature to allow us to capture and share knowledge and experience.

Depending on which system is used, the system can be ordered to get as much relevant data from a centralised database as possible, but Excel documents can also be added. There is a high diversity in types of sources and data and those all have their own way of requesting and input. Following input, not all data is available in the correct format. This is especially the case when multiple types of data, for example qualitative and quantitative information, are to be used together.

What the NIM does

This means the data must often be prepared for the analysis. This happens in the preparation phase. Here, raw data is transformed into a clear collection of data. This phase generally takes a lot of time, but it is essential for reliable and efficient analysis. If the data sets are large, as is the case with Big Data, other, advanced technologies are needed.

Now that all the data has been collected, cleaned, and entered, a selection must be made with relevant data. It may be the case that the customer behaviour data of the past five years are available, but the manager only wants to use the data of the past two years. Once the data are in a workable format, actual analysis can start.

This it where it is decided which cross-section must be made of the data.
