Both classification methods require that one know the land cover types within the image, but unsupervised allows you to generate spectral classes based on spectral characteristics and then assign the spectral classes to information classes based on field observations or from the imagery. The user specifies the various pixels values or spectral signatures that should be associated with each class. }] Supervised Classification supervised classification. iframe: { Supervised classification is based on the idea that a user can select sample pixels in an image that are representative of specific classes and then direct the image processing software to use these training sites as references for the classification of all other pixels in the image.

Clinical management and basic research of heterogeneous diseases, such as cancer, increasingly covers sophisticated technical systems and laboratory assays that may generate large volumes of high-dimensional data. (2008a,b) presented results of a supervised classification (maximum likelihood) applied to reconnaissance (acquired with 5000 m line spacing) AGRS data ( Figure 29 ). Supervised learning classified into two categories of algorithms: Classification: A classification problem is when the output variable is a category, such as “Red” or “blue” or “disease” and “no disease”. translation and definition "Supervised Classification", Dictionary English-English online. Training and Test Set: The whole data is usually divided into two parts, one used by the learning algorithm to learn a model (called training data) and the other one to evaluate the performance of the learnt model (called test data).For more details see the below posts. In supervised classification the user or image analyst “supervises” the pixel classification process. googletag.pubads().setTargeting("cdo_pt", "entry"); In the case of classification , the model will predict which groups your data falls into—for example, loyal customers versus those likely to churn.

Supervised classification is the process in which an artificial system (usually a computer program) is used to generate a predictive model (Classifier) based on numerical feature descriptions of real-world observations (samples) that are grouped in at least two different categories (classes).
