What is the difference between RandomSearchCV and GridSearchCV?
RandomSearchCV has the same purpose of GridSearchCV: they both were designed to find the best parameters to improve your model. The main difference between the pratical implementation of the two methods is that we can use n_iter to specify how many parameter values we want to sample and test.
Which dataset you would use for Hyperparameter tuning?
Hyperparameter tuning is a final step in the process of applied machine learning before presenting results. You will use the Pima Indian diabetes dataset.
Where does the data come from in grid control?
Typically, the rest of the rows contain data. Generally, this data comes from database tables. Usually, when you make the grid control, you place data items in the grid. The data items can come from the BV attached to the form, or they can be based on DD items. Either way, each data item becomes a column.
What’s the difference between a grid and an update grid?
A grid can either be a browse grid or an update grid. You can use a browse grid for viewing only, and you cannot select individual cells. The find/browse, search & select, power browse, and portlet browse forms have browse grids, as do browse subforms. You can use an update grid to add, delete, or update records.
How are grid controls different from edit controls?
Unlike an edit control, grid controls can show multiple data items and multiple table rows at once. You also can use grid controls to enable users to edit table records. In end-user documentation, grid controls are referred to as detail areas. A grid can either be a browse grid or an update grid.
When do you not need to store column IDs in grid?
Every time you walk a row, check each element’s column id (which needs to be stored along with all other data for an element) against the hash table and splice it out of the row if it has been deleted. The hash table and ids are unnecessary if you have a per-column data structure that each grid element can point to.
