One of the main reasons why there is no focus on robustness today is because it is hard to do in a general way. Regardless, complex systems should still handle any errors encountered gracefully. Some of the most robust systems are evolvable and can be easily adapted to definition of robustness new situations.

definition of robustness

In computer science, robustness is the ability of a computer system to cope with errors during execution and cope with erroneous input. Robustness can encompass many areas of computer science, such as robust programming, robust machine learning, and Robust Security Network. Formal techniques, such as fuzz testing, are essential to showing robustness since this type of testing involves invalid or unexpected inputs.

However, the difficulties in a theoretical explanation of robustness within the linguistic modelling suggested the adoption of an empirical notion. The word in the example sentence does not match the entry word. So the authors tried several different analysis techniques to test the robustness of the observed trend. The «robustness of coherence» of the input probe quantifies the quantum advantage. Improve your vocabulary with English Vocabulary in Use from Cambridge. There exists algorithms that tolerate errors in the input or during the computation.

Household balance sheets remain healthy, consumer spending is robust, and credit-card delinquencies are low. Your larger agency is probably more robust with its resourcing for projects—including project managers, account managers, multiple designers, creative directors, etc. Healthy implies full strength and vigor as well as freedom from signs of disease.

Definition of robustness – What it is, Meaning and Concept

This would be the case, for example, of “World of Warcraft”. In this sense, we should also emphasize that it leads to the determination of the robustness of a work method, which will be based on characteristics such as the influence function or what has been called the breaking point. The first step we have to take, before proceeding to analyze in depth the meaning of the term robustness, is to determine its etymological origin. In doing so we discover that it is a word that comes from Latin, and more specifically from the word “robustus” which in turn emanates from “robur”, which can be translated as “oak”.

definition of robustness

This is particularly due their vulnerability to adverserial attacks. In general, building robust systems that encompass every point of possible failure is difficult because of the vast quantity of possible inputs and input combinations. Since all inputs and input combinations would require too much time to test, developers cannot run through all cases exhaustively. Some selected inputs might consist of a negative number, zero, and a positive number. When using these numbers to test software in this way, the developer generalizes the set of all reals into three numbers. This is a more efficient and manageable method, but more prone to failure.

Robust machine learning

Sliding modes are used to determine best values for parameters in neural network learning rules, thereby robustness in learning control can be improved. Technical Analysis The technical analysis definition is a trading tool and method of analysing… If you are an investor you will have used many financial models.

This is meant to look like something that’s been around for a little longer and has a lot of durability and robustness to it. Nevertheless, the wear test alone is not sufficient to determine the robustness of the superhydrophobic surface. The respondents were polled again in 2012 to assess the robustness of their answers.

  • This would be the case, for example, of “World of Warcraft”.
  • This is a more efficient and manageable method, but more prone to failure.
  • However, observations in systems such as the internet or biological systems demonstrate adaptation to their environments.
  • When using these numbers to test software in this way, the developer generalizes the set of all reals into three numbers.
  • Recently, consistently with their rise in popularity, there has been an increasing interest in the robustness of neural networks.

For example, comparing similar species, rats have robust body types while mice are gracile. Male and female members of the same species may display sexual dimorphism and have robust and gracile morphologies. There are obviously specific signs for many words available in sign language that are more appropriate for daily usage. Similarly, change in the column temperature can affect the viscosity of the flow rate and thus influence the results by e.g. different retention times. Whether you’re a teacher or a learner, Vocabulary.com can put you or your class on the path to systematic vocabulary improvement.

It is an ability that not only allows the character to continue living but also to deal with the fulminating blows that his rivals try to land on him. A computer systemOn the other hand, it can boast of its robustness if it can execute several processes simultaneously without generating crashes or crashing . An example of a robust system is one for the creation of 3D graphics that makes it possible to work with very heavy images without problems. If he Program it hangs when loading the first image, it is a not very robust application.

definition of robustness

In a sense, robustness in network design is broad just like robustness in software design because of the vast possibilities of changes or inputs. The robustness of the phylogenetic analyses was assessed by trying various tree-building methods and several different evolutionary models. It’s an attribute of financial markets where they continue to perform as expected despite the change of certain parameters in an economic model of that market. It means that a model of a market works even as conditions change beyond the original ones. Hence, evaluation of robustness during development makes sense as parameters that affect the method can be identified easily when manipulated for optimization purposes.

Where have you heard about robustness?

Keep in mind, that particularly critical materials such as the column type used in a HPLC method or precast gels in a SDS-PAGE from a certain supplier might be no longer available one day in the future. It may therefore be advisable right from the beginning to consider such materials from different suppliers during initial validation. As can be seen from these examples, robustness does not always refer to the material. From the point of view of building learning abilities into artificial agents, simple mechanisms have obvious advantages in terms of robustness and design cost. Currently, computer science practices do not focus on building robust systems.

Is the ability of a computer system to cope with errors during execution and cope with erroneous input. Here are all the possible meanings and translations of the word robustness. Within the mathematical and statistical field, we have to emphasize that there is what is known as robust statistics. Robustness can refer to physical or symbolic characteristics.

You have requested a machine translation of selected content from our databases. This functionality is provided solely for your convenience and is in no way intended to replace human translation. Needs to review the security of your connection before proceeding. I examine the robustness of monetary equilibria in a random-matching model, where a more efficient mechanism for trade is available. The effectiveness and robustness characteristics of our proposed method were verified successfully in both simulations and experiments. By examining children who come to the task of language development facing environmental risks, the robustness of these sequences becomes evident.

When applying the principle of redundancy to computer science, blindly adding code is not suggested. Blindly adding code introduces more errors, makes the system more complex, and renders it harder to understand. Code that doesn’t provide any reinforcement to the already existing code is unwanted.

A construction that has been standing for several centuries shows its robustness by having withstood the passage of weather. This may be possible due to the quality of the materials and the ability of builders. On the other hand, if a construction begins to have structural failures five years after its birth, no one could highlight its robustness, since it is a weak and fragile building. These example sentences are selected automatically from various online news sources to reflect current usage of the word ‘robust.’ Views expressed in the examples do not represent the opinion of Merriam-Webster or its editors. Complex performance extends the analysis from individual environmental problems to larger issues of sustainability, fairness, efficiency, and robustness. Add robustness to one of your lists below, or create a new one.

The new code must instead possess equivalent functionality, so that if a function is broken, another providing the same function can replace it, using manual or automated software diversity. To do so, the new code must know how and when to accommodate the failure point. But as a system adds more logic, components, and increases in size, it becomes more complex. Thus, when making a more redundant system, the system also becomes more complex and developers must consider balancing redundancy with complexity. Robustness is the evaluation of an analytical method wherein the results obtained are found to be reliable even when performed in a slightly varied condition. It is the ability of a method to remain unaffected when slight variations are applied.

In that case, the computation eventually converges to the correct output. Robust programming is a style of programming that focuses on handling unexpected termination and unexpected actions. It requires code to handle these terminations and actions gracefully by displaying accurate and unambiguous error messages.

It is based on the perceived strength and robustness of our economy. We look at reliability, robustness, and performance as features of the design. This is unhealthy for the political robustness of the alliance and unfairly apportions the burden for the common defense. More examples We have several options for improving the robustness of the market. However, there are other games of this type that, in the same way, establish robustness as a quality for the participants.
