Molecular Shapes

Molecular Shapes

Molecules have characteristic shapes that are crucial for their function. The arrangement of various electron groups around the central atom dictates their molecular geometry. Electron pairs in the valence shell of a central atom will adopt an arrangement that minimizes repulsions between the electron pairs by maximizing the distance between them. The valence electrons form either bonding pairs, located primarily between bonded atoms, or lone pairs.

Molecular Models

Molecular Models

Physical models representing molecular architectures of chemical compounds play essential roles in understanding chemistry. The use of molecular models makes it easier to visualize the structures and shapes of atoms and molecules.

Newman Projections

Newman Projections

Different notations are used to represent the three-dimensional structure of molecules on two-dimensional surfaces. One of the most commonly used representations is the dash-wedge formula. The dashed wedges, solid wedges, and the plane lines indicate the groups situated behind the plane, coming out of the plane, and in the plane, respectively.
The organic molecules rotate across the single bonds leading to numerous temporary three-dimensional structures of varying energy known as...

Protein Organization

Protein Organization

Proteins are polymers of amino acid residues. They are versatile and responsible for different cellular functions, including DNA replication, molecular transport, catalysis, and structural support. Proteins have a hierarchical structure comprising at least three levels of organization: primary, secondary, and tertiary structure. Some large proteins have a quaternary structure where individual protein subunits are linked together.
The primary structure of a protein is its amino acid sequence....

Background:

Representation-based classifiers (RCs) are popular in pattern recognition and computer vision.
Existing RCs often process test samples independently, neglecting inter-sample correlations.
A unified framework, Atomic Representation-based Classifier (ARC), has been proposed.

Purpose of the Study:

To present a general framework, Atomic Representation-based Classifier (ARC), unifying existing representation-based classifiers.
To develop a Structural ARC (SARC) that leverages correlations among test samples.
To improve the performance of classification tasks by incorporating structural information.

Main Methods:

Developed a general framework termed Atomic Representation-based Classifier (ARC).
Introduced Structural ARC (SARC) using Bayesian analysis.
Generalized a Markov random field-based multilevel logistic prior for SARC.

Main Results:

Demonstrated that most popular RCs are special cases of ARC.
Showcased SARC's ability to utilize structural information among test data.
Achieved improved classification performance on synthetic and real datasets.

Conclusions:

The proposed ARC framework provides a systematic unification of various representation-based classifiers.
SARC effectively incorporates structural information among test samples, enhancing classification accuracy.
The SARC framework offers a promising direction for advancing representation-based classification methods.
