Bat Call Identification with Gaussian Process Multinomial Probit
... We approach bat call identification as a classification problem where the class response variables yn ∈ {1, . . . C} indicate the species id for the nth call in the library and x ∈ RD is a D-dimensional vector representation of the call, e.g. features extracted from the call’s spectrogram. We will d ...

Discretization of Target Attributes for Subgroup Discovery
... The task of subgroup discovery is defined as follows. Given a data set that is representative of a particular population, find all statistically interesting subgroups of the data set for a given target attribute of interest. Target attributes may be binary, nominal, or continuous. Many subgroup disc ...

Mining Association Rules Based on Certainty
... When sup(X ⇒ Y ) ≥ min sup and min con f ≥ P(Y | X) ≥ P(Y ), we may miss some important association rules. Due to P(Y |X) ≤ min con f , output X ⇒ Y would not be strong association rule. But P(Y |X) ≥ P(Y ) shows that the probability of Y increased under the premise of X. Instance X deduced Instance ...

Expectation–maximization algorithm
In statistics, an expectation–maximization (EM) algorithm is an iterative method for finding maximum likelihood or maximum a posteriori (MAP) estimates of parameters in statistical models, where the model depends on unobserved latent variables. The EM iteration alternates between performing an expectation (E) step, which creates a function for the expectation of the log-likelihood evaluated using the current estimate for the parameters, and a maximization (M) step, which computes parameters maximizing the expected log-likelihood found on the E step. These parameter-estimates are then used to determine the distribution of the latent variables in the next E step.
