A sampler is an electronic musical instrument that records and plays back samples (portions of sound recordings). Samples may comprise elements such as rhythm, melody, speech, sound effects or longer portions of music.
Orange is a powerful platform to perform data analysis and visualization, see data flow and become more productive. It provides a clean, open source platform and the possibility to add further functionality for all fields of science.
The work of samplers is aimed at taking onsite samples, either in open-cast or underground workings of the mine. They visit different sections of the mine on a daily basis to take ore samples. This is a specialised task, since the information obtained from the ore is vital for planning.
The Data Sampler widget implements several means of sampling data from an input channel. It outputs a sampled and a complementary data set (with instances from the input set that are not included in the sampled data set). The output is processed after the input data set is provided and Sample Data is pressed.
Loading your data Orange can import any comma, . xlsx or tab-delimited data file or URL. Use the File widget and then, if needed, select class and meta attributes. To specify the domain and the type of the attribute, attribute names can be preceded with a label followed by a hash.
Double-click the feature label in the function row and select target instead. This will set function attribute as our target (class) variable. You can also change attribute type from nominal to numeric, from string to datetime, and so on. Naturally, data values have to suit the specified attribute type.
