Early stopping
| Глоссарий по искусственному интеллекту |
A technique to avoid overfitting in neural network and other adaptive data modeling tools. essentially the data is divided into a training and validation set and the modeling technique is "detuned" to learn very slowly. as the model learns on the training set, the error in the validation set is monitored, and the learning (maximization) process is stopped when the error in the validation set starts to go up. in practice, the validation error can vary while it is still decreasing overall (and likewise can appear to decrease when the overall trend is upward). one approach to avoid this problem is to store the intermediate models while training the system to convergence and then back out to the true minimum (i.e., overshoot and correct). elaboration of this technique are available.

Ear, английский
- The organ of hearing and equilibrium in vertebrates, in humans consisting of an external ear that gathers sound vibrations, a middle ear in which the vibrations resonate against the tympanic membrane, and a fluid-filled internal ear that maintains balance
- Effective air path
- Electromagnetic activity receiver
- Electronically agile radar (program)
- Engineering analysis report
- An organ on the side of the head which is used for hearing (note: for other terms referring to ears, see auricular and words beginning with ot-, oto-.) comment: the outer ear is shaped in such a way that it collects sound and channels it to the eardrum. behind the eardrum, the three ossicles in the middle ear vibrate with sound and transmit the vibrations to the cochlea in the inner ear. from the cochlea, the vibrations are passed by the auditory nerve to the brain. ear, nose & throat ear, nose & throat /?? n??z ?n ?r??t/
- A west-country term for a place where hatches prevent the influx of the tide.

Overfitting, английский
- A term used in neural networks, recursive partitioning, and other automated modeling areas. if the training data is considered to consist both signal and noise (i.e., noisy data), a modeling technique has begun to overfit when it begins capturing the "noise" instead of the "signal." this usually occurs when a model is allowed to increase its number of "parameters`` such as regression coefficients, splits in recursive partitioning schemes, or hidden units in neural networks. the effect of overfitting is to reduce the applicability of the model to other data sets, (i.e., to limit its generalizability). in the extreme, the model can only "predict" its input. the most straight-forward way to eliminate this effect is to require a very large number of observations per parameter in the model.
- A problem in data mining when random variations in data are misclassified as important patterns. overfitting often occurs when the data set is too small to represent the real world.
Essentially, английский

- No существу; главным образом
Validation, английский
- Confirmation that particular requirements for a specific intended use are fulfilled.
- Action or process of proving that a procedure, process, system, equipment, or method used works as expected and achieves the intended results. [clsi]
- Утверждение
- Подтверждение соответствия; проверка
- Валидация. подтверждение путем экспертизы и представления объек-тивного доказательства того, что особые требования, предназначенные для конкрет-ного применения, соблюдены [4]. см. также method validation (валидация метода).
- The process of determining the correctness of a standard as to its technical completeness and lack of ambiguity. (ieee)
- The process in which microsoft tests an app to make sure it meets app requirements.
- The process of comparing files on local volumes with their associated data in secondary storage by remote storage. volumes that are validated ensure that the correct data is recalled from remote storage when a user attempts to open the file from a local volume.
- The process of confirming that data passing into the system is correct and complies with predefined rules, definitions, or parameters.
- Валидация. подтверждение путем экспертизы и представления объективного доказательства того, что особые требования, предназначенные для конкретного применения, соблюдены [4]. см. также method validation (валидация метода).

- Сходимость; схождение; сужение; конвергенция; затухание (колебаний)
- The bending of light rays toward each other, as by a positive (convex) lens.
- The ability to use both eyes as a team and to be able to turn the eyes inward to maintain single vision close up.
- The simultaneous turning in of the eyes to keep an object in sight as it comes nearer to the eye.
- N конвергенция
- A horizontal inflow of air.
- Literally, comming to a point with time. the values in the sequence 1, 1/2, 1/3, 1/4, ••• converge to zero whereas the values in the sequence all, 1/2,2/3,3/4, ••• converge to one. convergence requires that the differences between neighboring values decrease. if they do not, they may tend to infinity as in 1,2,3, ••• or end up oscillating as in ••• +1, -1, +1, -1, •••• the convergence model of communication postulates that as people communicate with each other they become more similar in knowledge and in attitudes and thus converge to form a homogeneous distribution.

Kernel regression, английский
A technique that bases predictions, or classifications, on the values of other cases that is within a given distance of the target case or observation. typically, the influence of other cases is weighted by their distance from the target. see also: classification, data mining, regression.
Bag of words representation, английский
A technique used in certain machine learning and textual analysis algorithms, the bag of words representation of the text collapses the text into a list of words without regard for their original order. unlike other forms of natural language processing, which treats the order of the words as being significant (e.g., for syntax analysis), the bag of words representation allows the algorithm to concentrate on the marginal and multivariate frequencies of words. it has been used in developing article classifiers and related applications. as an example, the above paragraph would be represented, after removing punctuation, dumplicates, and abbreviations, converting to lower-case and sorting as the following list: a algorithm algorithms allows analysis and applications article as bag been being certain classifier collapses concentrate developing for forms frequencies has in into it language learning list machine marginal multivariate natural of on order original other processing regard related representation significant syntax technique text textual the their to treats unlike
