Mount Everest, Earth's highest mountain. A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock.Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (980 ft) above the surrounding land.

Information overload (also known as infobesity, [1] [2] infoxication, [3] or information anxiety [4]) is the difficulty in understanding an issue and effectively making decisions when one has too much information (TMI) about that issue, [5] and is generally associated with the excessive quantity of daily information.
Thus, by definition from equation (i): (Information gain) = H(t) - H(s,t) After all the steps, gain(s), where s is a candidate split for the example is: gain(s) = 0.985 – 0.857 = 0.128 The newly created tree with the root node split based on Mutation 3. Mutation 3 had the highest information gain, so it was selected as the split.
In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees.
where is the Kullback–Leibler divergence, and is the outer product distribution which assigns probability () to each (,).. Notice, as per property of the Kullback–Leibler divergence, that (;) is equal to zero precisely when the joint distribution coincides with the product of the marginals, i.e. when and are independent (and hence observing tells you nothing about ).
By definition, information is transferred from an originating entity possessing the information to a receiving entity only when the receiver had not known the information a priori. If the receiving entity had previously known the content of a message with certainty before receiving the message, the amount of information of the message received ...
