Beyond Static

Exploring Machine Learning for Adaptive Geometries in Expandable Structures

DigitalFUTURES International Workshop – 2023 | Computation, Assembly, Modules, Geometry, Machine Learning 

Type: Individual work

Software: Rhino, Grasshopper, Kangaroo 2, Kohonen Map & Voxeltools

Instructors: Hesham Shawqy & Esther Rubio Madronal

This study draws inspiration from grasshopper biomechanics and contemporary innovations, such as the Yaheetech Sideline Bench, to explore modularity and adaptability in design. Starting with foundational principles, it seamlessly integrates advanced techniques for a harmonious fusion guided by expansion and assembly strategies. The methodology refinement incorporates Machine Learning, specifically Self-Organizing Maps (SOM) by Teuvo Kohonen, diverging from conventional neural networks for a fresh perspective on design optimization.

Module & Geometry Rules

Basic Rules

Revised Rules (Adapted from the Basic)

The application of these principles in the assembly system, ensuring a thorough check of module assembly and a harmonious integration of designs with adaptability strategies.


For the next rounds of SOM iterations, 
create 20 varied input models using a randomizer with a Gene Pool component, ensuring diversity in architectural elements for optimized design outcomes. 

Aggregation – Assembly System

Machine Learning – SOM

In the ML process with SOM, cycles are performed, reducing dimensions until colors are well-defined, as seen in the iteration steps in the image, with the cycle reaching a maximum at 37. By the 36th cycle, the results have already repeated. 

Cycle #1 – #35.

Cycle #37 (final).

After 37 cycles, 10-dimensional ’glyphs’ condense into a two-dimensional map, resembling the image from Cycle 37. Each circle represents the central value of each dimension, and 10 models are selected based on the RGB map as representatives.
