Proficient Valuation and Estimation of Human Performance in Collective Learning Environments using Machine Learning

Abstract: Novel organic single Machine learning has fascinated more and more attention in the past few decades. In this paper, we have proposed machine learning-based system architecture and algorithms to find patterns of learning, interaction, and relationship and effective valuation for a complex system involving massive data that could be obtained from a proposed collective learning environment (CLE). Collective learning may take place among larger team members to find solutions for real-time events or problems, and to discuss concepts or interactions during situational judgment tasks (SJT). Modelling a collective, networked system that involves multimodal data presents many challenges. This paper focuses on proposing a Machine Learning - (ML)-based system architecture to promote understanding of the behaviours, group dynamics, and interactions in the CLE. The designed framework integrates techniques from computational psychometrics (CP) and deep learning models that include the utilization of convolution neural networks (CNNs) for feature extraction, skill identification, and pattern recognition. The proposed framework also identifies the behavioral components at a micro level, and can help us model behaviors of a group involved in learning.

2-Bromo-N'-[(Z)-2-bromo-benzyl-idene]-5-methoxy-benzohydrazide.

Abstract: In the title compound, C15H12Br2N2O2, the mol­ecule adopts an E conformation about the C=N double bond and a transoid conformation about the central N—N bond, with a C(=O)—N—N—C(H) dihedral angle of 169.4 (4)°. In the crystal, mol­ecules are linked by N—H⋯O hydrogen bonds, leading to C(4) chains. The packing also features slipped π–π stacking inter­actions, with a centroid–centroid separation of 3.838 (3) A and a slippage of 1.19 A.

Methyl 5-chloro-1H-indole-2-carboxyl­ate

Abstract: In the mol­ecule of the title compound, C10H8ClNO2, the indole ring system is planar. In the crystal structure, the mol­ecules are linked by inter­molecular N—H⋯O hydrogen bonds, forming centrosymmetric dimers.

2-Bromo-1-(4-methylphenyl)-3-4-(methylsulfanyl)phenyl]prop-2-en-1-one

Abstract: The title compound, C17H15BrOS, crystallizes in a non-centrosymmetric space group and shows significant nonlinear optical activity.

3-(Biphenyl-4-yl)-2,3-dibromo-1-(2,4-dichloro­phen­yl)propan-1-one

Abstract: The two aromatic rings of the biphenyl group of the title compound, C21H14Br2Cl2O, are not coplanar and the carbonyl group is twisted out of the plane of the adjacent dichlorophenyl ring. The crystal packing is stabilized by C-H center dot center dot center dot O and C-H center dot center dot center dot Br contacts.
