The two-volume set LNAI 7120 and LNAI 7121 constitutes the refereed court cases of the seventh foreign convention on complex information Mining and purposes, ADMA 2011, held in Beijing, China, in December 2011. The 35 revised complete papers and 29 brief papers offered including three keynote speeches have been rigorously reviewed and chosen from 191 submissions. The papers conceal quite a lot of issues proposing unique examine findings in information mining, spanning purposes, algorithms, software program and structures, and utilized disciplines.

**Swarm Intelligence for Multi-objective Problems in Data Mining**

The aim of this publication is to assemble contributions which are on the intersection of multi-objective optimization, swarm intelligence (specifically, particle swarm optimization and ant colony optimization) and knowledge mining. one of these assortment intends to demonstrate the potential for multi-objective swarm intelligence thoughts in information mining, with the purpose of motivating extra researchers in evolutionary computation and desktop studying to do learn during this box.

**Best Practices for Dust Control in Metal-Nonmetal Mining**

Compiled by means of the U. S. Dept of healthiness and Human prone, CDC/NIOSH workplace of Mine security and future health examine, this 2010 instruction manual was once constructed to spot to be had engineering controls that may help underground and floor metal/nonmetal mining operations in decreasing employee publicity to respirable silica dirt.

**Effective Database Design for Geoscience Professionals**

Geotechnical facts administration performs a key position in challenge fixing for oil corporation exploration and improvement operations. handling geotechnical facts frequently takes a distinct expert - one with either an engineering and IT heritage. potent Database layout for Geoscience pros is a whole handbook that geoscientists can use to supply a easy creation to facts administration options.

None of these objects are similar on all attributes, therefore we could consider two objects to be similar overall if they have similar evaluations on a majority of attributes. For example objects a and b have close evaluations on three out of four attributes, therefore they are considered to be globally similar. Objects c and d have also three attributes out of four on which they are similar. But on the ﬁrst attribute, they show a very large diﬀerence in evaluations (4 cm compared to 20 cm). Here, we would rather like to say that we are not sure if they are similar or not.

10) y∈X If x is mostly similar to K and compares to the rest of the objects in X mostly the same as the objects in K then f ∗ (x, K) will be high. Finally we deﬁne the ﬁtness of a partition, with respect to the crisp similarity relation, as the outcome of the clustering method through fP∗ : O(X) → [−n2 , n2 ], where O is the set of all possible partitions of X: fP∗ (K) := s∗ (x, y) + K∈K x,y∈K −s∗ (x, y). (11) K1 =K2 ∈K x∈K1 ,y∈K2 As the clustering result will be a partition, we wish to maximize this ﬁtness function and therefore will use it as the criterion to be optimized.

Let us deﬁne now the ﬁtness an alternative x would have as part of a cluster K through function f ∗ : X × P(X) → [−n2 , n2 ] as: f ∗ (x, K) := s∗ (x, y) · smm∗ (x, K). (10) y∈X If x is mostly similar to K and compares to the rest of the objects in X mostly the same as the objects in K then f ∗ (x, K) will be high. Finally we deﬁne the ﬁtness of a partition, with respect to the crisp similarity relation, as the outcome of the clustering method through fP∗ : O(X) → [−n2 , n2 ], where O is the set of all possible partitions of X: fP∗ (K) := s∗ (x, y) + K∈K x,y∈K −s∗ (x, y).
