Thomas W. Edgar, David O. Manz, in Research Methods for Cyber Security, 2017. Illustration of the input nodes, hidden layer, and output layer of a neural network. This type of research includes theorizing or defining how a cyber system and its environment behave and then exploring or playing out the implications of how it is defined. This involves a realistic evaluation of individual priorities, environmental demands, and biological capacity. Before a researcher can acceptably write about their research, they need to establish it within existing theory. Published on October 14, 2015 by Sarah Vinz. Indeed, more research effort has been devoted to fast computing for neural networks than to their theoretical properties. New communication protocols and paradigms are often simulated to test their behavior in a broad range of cases before it becomes worth the cost to manufacture and test new communication devices. ; You can frame your study by presenting the theoretical framework, reflecting that you have enough knowledge about your topic, relevant models, and theories. Several key terms are often used when discussing theory. For example, classic work has divided memory into three different stages, each with its own specific properties: (1) a sensory buffer, with a very large capacity but very brief duration, which uses a veridical code, with no translation of the input format (e.g., retinal image); (2) a short-term memory system, with a very limited capacity (7 ± 2) and relatively short duration, using a phonological code (i.e., sound) to assist the internal rehearsal process that avoids the decay of the trace over time (e.g., when whispering a telephone number between hearing it and dialing it); and (3) a long-term memory system, with an unlimited capacity (lifelong learning!) In a sense, a neural network is a black box, and it is hard to open the box. Second, neural network models do not admit a mathematical or computational description that is at once transparent and precise, so it is difficult to understand their behavior except phenomenologically, by looking at results such as misclassification tables. He wanted to make a contribution to knowledge in the field to which he was applying his methods not just to show that they ‘worked,’ but so he would set out to master the field. The three processes are also operative in institutions. His statistical contributions can be divided into ways of arranging numerical facts—univariate and multivariate—and methods of inference—estimation and testing. This is the creation of a theoretical cyber model. I assume you mean “literature reviews.” A theoretical literature review is included in pretty much every research paper you will see. Simulation provides the ability to produce automated sampling of a large variable space to test and understand a theoretical model with enough confidence to move forward, while also reducing the test space enough to be computationally possible. You should not document every proof; only highlight significant or interesting proofs as theorems. Theoretical research is a logical exploration of a system of beliefs and assumptions. There are many different lenses, such as psychological theories, social theories, organizational theories and economic theories, which may be used to define concepts and explain phenomena. Each term is defined and summarized in Box 4-1. However, it is also profoundly embedded in many studies of webs of activities. The three components—selection, optimization, and compensation—are regarded as fundamental processes or strategies to ensure adaptive development (P. B. Baltes 1997). PAR is a theoretical and methodological research paradigm involving both researcher(s) and communities under study as collaborative participants in generating knowledge that ultimately informs action (Coghlan & Brydon-Miller, 2014). Theoretical definition: A theoretical study or explanation is based on or uses the ideas and abstract principles... | Meaning, pronunciation, translations and examples Revised on October 22, 2020. Figure 1. A theoretical model will enable you to investigate how a cyber system would react under certain stimuli. Pearson was a tireless worker for whom empirical research and theoretical research went hand in hand. The discrepancy DN for a random number set {s1, s2, s3,…} with respect to the interval [a,b] is defined as. The initial stage of data collection depends largely on a general subject or problem area, which is based on the analyst's general perspective of the subject area. In addition, the user must select the particular nonlinear transfer functions to be applied at the nodes, and there are many choices for these as well. A theoretical approach is what you would use to drive your study, whereas an analytical approach is what drives your methodology. These models can be used to help develop and inform questions for other types of cyber science. Existing only in concept and not in reality: In cyber security research, theoretical work often overlaps with mathematics, logic, or theory of computation; cryptography, of course, is a great example of this. Two related, yet distinct, meanings of theory Synonym Discussion of theory. The process of selection refers to a reduction or transformation of domains of functioning in which the individual strives to perform efficiently. But note should be taken that none of these figures of merit can guarantee the performance of the generator in the real applications. In the results section of your paper, explain what you found after you performed your analysis. Essentially this means to compute optimal values for the many weight parameters (coefficients); this is done iteratively, by comparing the network's output to the known classifications of cases in the learning sample, and then adjusting the coefficients until the closest possible match is obtained. First, admission age has raised considerably. This is primarily due to the fact that theoretical work is in logical space where theories must be modeled and represented in some language. Another issue that has attracted a lot of interest and research effort is whether certain internal operations are performed sequentially (in serial stages) or simultaneously (in parallel). Test your knowledge - and maybe learn something along the way. Formal methods is another example of formal theory. Kotler and Keller (2003, p.60) rely on this definition, stating that"customer satisfaction is determined by the degree to which someone is happy or disappointed with the observed behavior of a product in relation to their expectations." First, complex models require complex computation. Given a specific architecture, transfer function, etc., the computing task is to train the network on the existing data. Generally, all cryptography and formal methods papers will fall into this class of research. For example, while not the only way, theoretical models are a good way to develop hypotheses. In the study, fatherhood researchers, practitioners, family members, and the fathers themselves developed a research agenda leading to policy recommendations to support fathers' well-being. Its key goal is to create a strong foundation for your future academic project. By theoretical evaluation, bad generators can be rejected immediately. As it is illustrated in figure below, theoretical sampling is systematically applied throughout the research processup to the generation of the grounded theory. Neural network models are typically nonlinear, with hundreds or thousands of parameters, and fitting these models to data presents a formidable computational challenge. Studies of computer artifacts in use need to focus on the narrow-use activity and the handling of the computer artifact, as well as on the wider context of use and design. Researchers must design clever experiments, with well-chosen experimental and control conditions, as well as manipulated and registered variables, to derive the internal representations and processes from observable responses such as response times and error rates.
