Visualization of a social network analysis (SNA) defined by a high-dimensional parameter space (21 dimensions). Dimensionality reduction (DR) is used here to allow the reduction of the number of variable that defines a system, into a lower dimensional space (2D). In this case I’m using self-organizing maps (SOM), which represent a type of unsupervised artificial neural network, to reduce the high dimensionality of the data whilst also retain the high-dimensional non-linear associations.
Another feature extraction used (side by side image), is a linear feature extraction method -> K-means cluster analysis, (although linear methods don’t retain the associations distributed non-linearly in the high dimensional space). #owl #machinelearning #machinelearningalgorithms #artificialintelligence #nextarch #nonstandardstudio #architecture #parametricdesign #agentbasedsystems
