Why should we add noise to image for machine Learning?
In machine learning, noise refers to data errors or data which carry high proportions of meaningless information. Noise also refers to data that is not clearly understood by the user. It is sometimes called corrupt data.
Attribute noise occurs when one or more attributes is deviated from the general distribution of other attributes. The larger the deviation is for one or more observations, the more evidence there is that there is noise.
Glass noise refers to the ratio of contradictory data entries to the actual number of entries in the data being analysed. It refers to the number of duplicate entries which have been assigned different class labels.
Noise is added to increase the variability of images. This is in order to train the machine models to avoid overfitting.
When noise is added to images, it is able to manipulate the appearance of an image to seem of higher quality than it actually is. The optical illusion here is able to attract a physician or a human gaze bias.
Noise allows room for algorithm performance to be tested. This in a way helps to avoid overgeneralization.
It is a branch of artificial intelligence which trains computers to think similarly as humans, with minimal human effort. This is usually done through data exploration and pattern identification.
Supervised machine learning uses labelled datasets to train algorithms. This is for data classification or the accurate prediction of outcomes.
Unsupervised machine learning makes use of underlying patterns stemming from unlabeled datasets which have no references to labelled prediction.
Semi supervised machine learning, fuse is a large portion of unlabeled datasets in a small portion of labelled datasets.
Reinforcement is a form of machine learning which rewards a desired behavior or action and penalizes undesired ways. It makes machine learning models who make a sequence of decisions.
It is a form of optical illusion added to photos. It could be in the form of its brightness or color details.
It is the act of randomly varying the brightness or color details of an image. This is done with image sensors of a scanner or a digital camera.
But this type of noise patterns become noticeable on digital imaging sensors where they are longer exposure shots and certain pixels are prone to given more illuminating intensities beyond the average.
This kind of noise is camera dependent, as it is introduced by the camera after reading data from its digital sensor. It is most visible when there is an excessive brightness of images.
It helps in holding models accountable. Usually, learning models are only able to predict the tuning data, but unable to do so with the wider world. Training models expected to learn the patterns of the training data rather than memorizing them. This is where the addition of noise to an image plays a major role.
Also, it helps to prevent unintended results. Noises are the two images because training models exhibit a higher rigidity level in their reasoning capacity. The noise adds to the flexibility of the model, helping to prevent overly generalized results.
Noise in images ensures strategic variations of results on training data. This is owing to the fact that it is added to all images before a training model learns to make inference.
