Nuemann therefore developed an algorithm to mechanically simulate the scrambling aspect of randomness as follows.įirst a truly random numbers called the seed (which could come from measurement of noise or the current time in milliseconds) is selected which is then provided as input to a very simple calculation where the seed is multiplied by itself, the middle of this output becomes the seed for the next step and the process repeated as many times as required. In 1946 while involved in running computations for the military, John Neumann required quick access to randomly generated numbers that could be repeated if necessary but as the computers of the time had very limited memory it could not store long random sequences. Random processes are nondeterministic since they are impossible to determine in advance whereas machines are deterministic because their operation is predictable and repeatable. Random walks have no pattern at all as the next point is always unpredictable. Such random sequences could be visualised using a random walk where a path is drawn that changes direction according to each number. Truly random numbers could be generated by measuring or sampling this noise such as the electric current of tv static over time. The physical world contans many truly random fluctuations everywhere. Khan Academy has a video that gives a very good overview of how seeds are used in random number generators at Khan academy random vs pseudorandom number generators from which the following notes are based. That is, it is a prime number of the form Mn = 2n − 1 for some integer n.). According to wikipedia, the Mersenne Twister is a pseudorandom number generator (PRNG) and is by far the most widely used general-purpose PRNG whose name derives from the fact that its period length is chosen to be a Mersenne prime (a prime number that is one less than a power of two. Python uses the Mersenne Twister as the core generator. There are many different ways to generate pseudo-random numbers. So by-default current system time is used as a seed value. However, When the first time you use the random generator, there is no previous value. Generally the seed value is the previous number generated by the generator. Setting a seed will produce the same sequence of random numbers each time. Computer random number generation algorithms are based on patterns which generate numbers that follow particular probability distributions. Psuedorandom numbers are suitable for purposes such as simulating datasets, testing machine learning algorithms etc as well as ensuring reproducibility of code for code sharing, teaching and demonstration purposes. Pseudorandom number generators should therefore not be used for cryptographic purposes because their predictability could be used to break the encryption but there are times when the exact same sequences of numbers may be required. Therefore if you know this seed then you can predict the next number to be generated in a sequence. This all means that the outputs can be repeated by following the same set of steps and given the same inputs. If you reinitialise a random number generator with the same seed, the default seed is ignored and the same sequence of pseudorandom numbers will be produced. These pseudorandom numbers contain no real randomness at all - randomness is just being imitated - but they can take the role of random numbers for certain applications. This means that while the numbers generated look random they are not truly random but pseudorandom. To recreate the exact same sequence of random numbers, then you can just explicitly supply the seed as an input to the random number generator. Pseudo random number generators can be seeded which makes them deterministic. This ensures that the same random sequence won’t be repeated unless you actually want it to. The random seed can be any number but it usually comes from seconds on the computer system’s clock which counts in seconds from January 1, 1970. The seed used is typically the time in milliseconds on the computer when the code was run and is used as the starting point of the process.Īccording to statisticshowto, a random seed specifies the start point when a computer generates a random number. Pseudorandom numbers are generated in a sequence according to some deterministic algorithm from an input called a seed which is a number that is used to initialise the pseudorandom number generator.

Within this group of apps, diet-tracking apps are very popular, with some downloaded as much as 50 million times (based on MyFitnessPal for Android market, April 2017). These apps have the potential to facilitate tracking of health-related behaviors and weight management. In 2017, a total of 325,000 mobile health (mHealth) apps were available in major app stores, and the number of users of mHealth apps will continue to rise in the upcoming years. Comparing the apps with the USDA reference for a 3-day diet, the average differences were 1.4% for calories, 1.0% for carbohydrates, 10.4% for protein, and −6.5% for fat.Ī large number of apps focused on health and fitness have emerged on the smartphone market. The exception to this was features related to the Reinforcement domain, which were correlated with less usability. The presence of behavior change domain features tended to be weakly correlated with greater usability, with R 2 ranging from 0 to. None of the apps allowed for tracking of emotional factors that may be associated with diet patterns. App features varied considerably, yet all of the apps had features consistent with Beliefs about Capabilities and thus have the potential to promote self-efficacy by helping individuals track their diet and progress toward goals. Some variations in features were noted between Android and iOS versions of the same apps, mainly for MyDietCoach, which affected the SUS score. Of the apps that were reviewed, LifeSum had the highest average SUS score of 89.2, whereas MyDietCoach had the lowest SUS score of 46.7. |
