The trees in a Rotation Forest are all trained by using PCA (principal component analysis) on a random portion of the data A decision tree is considered optimal when it represents the most data with the fewest number of levels or questions.

Related Topics: algebra, cartesian coordinate, coordinate plane, data plot, function properties, functions, graph, inequality, intervals, linear equations, linear functions Investigate the Cartesian coordinate system by directing a robot through a mine field laid out on the plane.Similar analysis should be conducted to construct the remaining columns of the reliability matrix.Fractal Dimensions is one of the Interactivate assessment explorers.Related Topics: chaos, fractals, geometric sequences, iteration, pattern, pre-calculus, recursion, scale, self-similarity, sequences, symmetry, transformation Build a "floor tile" by dragging the corners of a quadrilateral.This activity allows the user to burn a virtual forest, then estimate the number, the percent, or the fraction of trees burned.The applet is similar to GraphIt, but instead allows users to explore the representation of a function in the polar coordinate system.Three levels of difficulty are available.On the tree, the value of a node can be calculated when we have the values for all the nodes following.Related Topics: assessment, cartesian coordinate, coordinate plane, function properties, functions, graph, lines, pre-calculus, vertical line test Give input to the Whole Number Cruncher and try to guess what it did from the output it generates.For simplicity, consider a case where there are only two outcomes, with one having a probability.Whenever the decision maker has some knowledge regarding the states of nature, he/she may be able to assign subjective probability verlichte dansvloer maken estimates for the occurrence of each state.Conjunctions between nodes are limited to AND, whereas decision graphs allow for nodes linked.Related Topics: agent modeling, chaos, conditional probability, experimental probability, iteration, percentages, percents, probability simulation, proportion, simulation, skewed distribution, variance Create a game spinner with variable sized sectors to look at experimental and theoretical probabilities.This is a very powerful activity with a wide range of options.Related Topics: conditional probability, events, experimental probability, outcomes, probability, probability simulation, probability without replacement, statistics, theoretical probability, theoretical value, trials Sort colored shapes into a Venn diagram based on various characteristics.Calculations can become complex when dealing with uncertainty and lots of linked outcomes.Parameters: Level of difficulty and types of questions.
This type of tree is also known as a classification tree.
If you are uncertain, and would use the expression "I really don't know the event may or may not occur with a probability.
