Determination of suitable sampling methods for study of canopy cover in the Oak Forest
To detection of suitable sampling method to study tree canopy cover in the northern Zagros forest, Baneeh region forest, Kurdistan province, and west of Iran was selected. 40 square sample plots one hectare (100×100 m) were selected and perfect inventoried. In every sample plot the position of tree, kind of species and two diameter of crown (m) were recorded. To study of canopy cover different ...

متن کاملSampling Methods for Random Subspace Domain Adaptation
Supervised classification tasks like Sentiment Analysis or text classification need labelled training data. These labels can be difficult to obtain, especially for complicated and ambiguous data like texts. Instead of labelling new data, domain adaptation tries to reuse already labelled data from related tasks as training data. We propose a greedy selection strategy to identify a small subset o...
متن کاملSelective Sampling Using Random Field Modelling
Most existing inductive learning algorithms assume the availability of a training set of labeled examples. In many domains, however, labeling the examples is a costly process that requires either intensive computation or manual labor. In such cases, it may be beneecial for the learner to be active by intelligent selection of examples for labeling with the goal of reducing the labeling cost. In ...
متن کاملComparing power among three sampling methods for monitoring forest vegetation
We compared three methods of sampling forest vegetation for their ability to reliably estimate changes in species richness, plant abundance, and overstory basal area and composition. Methods include the US Forest Service’s Forest Inventory and Analysis (FIA) method and two other methods being considered for use in monitoring National Parks in the Northern Great Lakes ecoregion. All methods were...
