Sam to Present at MIT

As part of a collaboration wit the Digital Structures Lab, Sam has been invited to do a presentation on latest work anf thinking of his group. The talk is outlined below:

Collaboration with Computers
The work of Meta Design Lab in Singapore
There has been much talk recently about the ‘take over’ of white collar jobs by AI. However at the same time studies have shown that Architecture and design are some of the least likely to be automated jobs (2% likely or 338th of 366 most likely to be automated*). This talk discusses why this is, what is special about creative activities that resists automation, but also debates if this resistance is a good thing. If we as an industry can’t automate will we fall behind other industries, if we haven’t already? It then considers a third way, what would it mean for a collaborative creative co-design; for designers to work with computers effectively and presents the labs work investigating ways humans and machines can design together including generative meta-parametric design, mixed-initiative methods and option exploration.

The Talk will be held on Dec 4th, and more details can be found via this site:

Sam Presents at Singapore Archifest SIA Conference

The lab was honoured to be asked to explore the theme of craft in relation to developing technology and research and its impact on architecture.
The talk synopsis is below

The Crafting of Craft
The theme of Archifest this year offers an opportunity to consider what is craft now: As we are firmly cementing our position in the information age, this digital epoch like those before it is transforming the nature of what is considered craft. This talk aims to demonstrate that these digital technologies are not incompatible to classical craft, but can draw a trajectory though key society transforming moments and crafts of the 20th century and earlier. Reflecting on how these extended mankind's capabilities for manipulating its environment, whilst at the same time expanding human thought. Leading to considerations on its relation to expanding the field of architectural craft and yet still linking us to the past.

Award of Aviation Project "Horizon 2050"

Meta Design Lab are please to be able to share their new funded project. Titled "Horizon 2050" it asks what the future of aviation and specifically airport design will be over the next two decades by the year 2050.
Focusing on the rapidly expanding South East Asian region this project seeks to develop insight into the social, global, and market forces that will drive demand and design requirements for new and existing terminals.
It seeks to survey new disruptive technologies to see how this will influence teh airport and city-airport relationship, and present new approaches ideas in what airports will look like to address the their growing demands.

Over its 5 years planned duration the project aims to assess the impact and develop methods that airport terminals will adapt though five scales of concern:
1. – The global economic network : passenger growth, demographics, and changing landscape of owner-operators with its impact on airport buildings,
2. – The air city link : how the airport and connecting infrastructure will relate to the city and vice-versa,
3. – The terminal plan : what will drive new terminal configurations and what new solutions can accommodate this,
4. - Building Tectonics : how new terminal buildings can be constructed to be more efficient and sustainable,
5. – User Experience : how technology and user demands will change design requirements on the airport to improve passenger and worker experience

We look forward to developing this project with partners over the duration.
Please contact us if you are interested in the results.

SUTD IDC Talk – Generating Novelty : Exploring beyond parametric generative design.

Sam Joyce will be holding a talk at the IDC Seminar Series on research looking at approaches to computationally generating diverse parametric designs.

Abstract:
Current state of the art in Architecture often centers around the use of parametric associative design tools. These allow for wider automation of geometric operations, and exploration including optimisation of design space than possible with more analogue approaches. However with greater familiarity of these tools has begun to show inflexibly and difficulty in terms of reconfiguring the parametric models to generate new solutions. This research looks at the use of Cartesian Genetic Programming to automatically build Directed Acyclic Graphs, these can replace models as built by human users. This ‘Meta-Parametric’ method allows for a near infinite number of possibilities, potentially much wider exploration of design space; however equally this creates new challenges in how to filter out ‘deign-noise', direct, and derive meaning from an approach which now has too much design diversity. User lead interactive evolutionary optimisation is shown as potential way that also opens up new ways for human and computers to co-create.

Smart Geometry Cluster

Meta Lab's Sam Joyce and Verina Cristie are pleased to be involved in Smart Geometry 7-12th May 2018 in Toronto.

The cluster is entitled 'behavioural enviro[NN]ments' and undertaken in collaboration with Kate Jeffery a Professor of Behavioural Neuroscience and Wellcome Trust Investigator at UCL and Jonathan Irawan a Computational Designer at Hassell Studio.

A synopsis of the cluster aims are below:
Autonomous, hyper adaptive and responsive buildings and environments have been a topic of obsession for many designers and architects since the 1960s. Nicholas Negroponte envisioned a system that enables an architect to create an intelligence to design the building themselves. Within the Architecture Machine Group at MIT, they created The ‘Seek’, a computer-controlled landscape environment full of small blocks which were inhabited by gerbils. It was the task of the machine to analyse the variation between reality and virtual models with the responsibility of keeping the original plan intact if possible, which was then used to predict the future behaviour of the gerbils. Unfortunately however, the system was not successful, due to an unclear criteria and high number of permutations in variables of disruptions and behaviour. The cluster will revisit the project, incorporating modern advancements in Machine learning algorithms and techniques to transform our own version of the dynamic environment itself into a neural network. The environment, in an attempt to predict the occupancy behaviour and usage pattern preferences of gerbils, will utilise reinforcement functions based on movement(navigational) patterns and spatial usage. The final aim is to create a landscape that would best suit the daily behaviour or activities of the small animal subjects.

Meta Parametric Design : Interactive Website
Exploring the evolution convergence of parametric models

Work presented at ACADIA 2017 in MIT, Massachusetts. The research investigates the effect of applying genetic programming applied to parametric models. We look into measuring the geometric and parametric complexity of models which are derived through evolutionary optimisation. Parametric models are defined as genomes using Cartesian Genetic Programming a method of developing logical structures which are consistent with parametric definitions. These enable machine learning processes to manipulate and define autonomously parametric models.
This work has a complimentary website, where you are invited to explore the process. Using basic parametric components and automatically generated designs, which are optimised both based on hard objectives and also user interaction.

Parametric Design Space Exploration Site On-Line

We have some initial work by Nazim on exploring on the web how we can see the development of models which have been evolved. Here we look at 'Meta-parametric' models a higher level computational representation of parametric model which could open the doors to A.I. based creativity in architectural design. The aim is to understand the effects of application of Cartesian Genetic Programming (CGP) [Miller, Julian F. 2011] as a mechanism to construct and control parametric models generatively using an evolvable digital genome. Initial results are exciting as the point to effects on the performance and complexity of the parametric model and resultant output geometry.

This tool allows one to see the effects of a chosen number of iterations of evolution on a chosen population size, using a selectable 'palette' of components under different mating and selection criteria.

The research is ongoing and being developed for publication.

Discovering Design Change Pattern Through Versioning and Entropy Measurement

Abstract:
Despite the plenty of data collected through collaborative design exercises in pedagogy settings, very few of these data were utilized for further studies. This occurrence is in contrast with the software development settings where software repositories are often mined to find insights on programmer's software building pattern. In this work, we implemented exploratory time-series data analysis through design versions data collected from a parametric design workshop of 44 students in groups of five. A framework to discover design change pattern through in-between change count and its entropy calculation was developed. The result revealed three different change patterns the group exhibit: premature fixation, constant change, and last-minute work. Furthermore, a moderately strong correlation was found between design change entropy score and instructor's given final design score.

Machine Learning for Comparative Urban Planning at Scale: An Aviation Case Study

Abstract:
Aviation is in flux, experiencing 5.4% yearly growth over the last two decades, however with COVID-19 in aviation was hard hit, this along with its contribution to global warming has lead to louder calls to limit its use. This situation puts emphasis on how urban planners and technologists could contribute to understanding and responding to this change. This paper explores a novel workflow of performing image-based Machine Learning (ML) on satellite images of over 1000 world airports which were algorithmically collated using European Space Agency Sentinel2 API. From this the top 350 US airports were analysed with land use parameters extracted around the airport using Computer Vision, which were mapped against their passenger footfall numbers. The results demonstrate a scalable approach to identify how easy and beneficial it would be for certain airports to expand or contract and how this would impact the surrounding urban environment in terms of pollution and congestion. The generic nature of this work- flow makes it possible to potentially extend this method to any large infrastructure, and also compare and analyse specific features across large number of images while being able to understand the same feature through time. This is critical in answering key typology based urban design challenges at a higher level and without having the need to perform on-ground studies which could be expensive and time consuming.

Examining Design-Centric Test Participants in Graphical Perception Experiments

Abstract:
In this paper, we replicate a foundational study in graphical perception, and compare our findings from using design-centric participants with that of previous studies. We also assess the visual accuracy of two groups, students and professionals, both with design backgrounds, to identify the potential effects of participants‘ backgrounds on their ability to accurately read charts. Our findings demonstrate that results for reading accuracy for different chart types of previous empirical studies are applicable to participants of design backgrounds. We also demonstrate that besides significant differences in response time, there are no significant differences in reading accuracy between the student and professional groups in our study. This indicates that, despite bias in research participants for visualization research, previous conclusions about graphical perception are likely applicable across different populations and possibly work fields.

User Directed Meta Parametric Design for Option Exploration

Abstract:
The potential of parametric associative models to explore large ranges of different designs is limited by our ability to manually create and modify them. While computation has been successfully used to generate variations by optimizing input parameters, adding or changing ‘components’ and ‘links’ of these models has typically been manual and human driven. The intellectual overhead and challenges of manually creating and maintaining complex parametric models has limited their usefulness in early stages of design exploration, where a quicker and wider design search is preferred. Recent methods called Meta Parametric Design using Cartesian Genetic Programming (CGP) specifically tailored to operate on parametric models, allows computational generation and topological modification for parametric models. This paper proposes the refinement of Meta Parametric techniques to quickly generate and manipulate models with a higher level of control than existing; enabling a more natural human centric user-directed design exploration process. Opening new possibilities for the computer to act as a co-creator: able to generate its own novel solutions, steered at a high-level by user(s) and able to develop convergent or divergent solutions over an extended interaction session, replicating in a faster way a human design assistant.

Seeing Numbers: Considering the Effect of Presentation of Engineering Data in Design

Abstract:
Computing has made detailed design analysis across all engineering domains types easier to produce, this has as a result generated significantly more design data than before. Similarly, tools like parametric modelling, and BIM have also allowed for differentiated design options to be generated faster and at lower human effort than previous design methods. This is leading to what the authors call “big- design-data”; large amounts of data which rather than being passively collected, have been generated during design and analysis of options. This data suffers from the same issues of data volumes and complex relationships (albeit not as large as classical big-data) and so in need of visualisation and interpretation to allow for meaningful insight which in turn can result in effective decisions. This paper explores the details of the issues and considerations of visualising data for designers and engineers specifically in relation to design decision making; identifying relevant research that supports how one may approach sense making in this big-design-data context.

GHShot: a collaborative and distributed visual version control for Grasshopper parametric programming

Abstract:
When working with parametric models, architects typically focus on using rather structuring them (Woodbury, 2010). As a result, increasing design complexity typically means a convoluted parametric model, amplifying known problems: `hard to understand, modify, share and reuse' (Smith 2007; Davis 2011). This practice is in contrast with conventional software-programming where programmers are known to meticulously document and structure their code with versioning tool. In this paper, we argue that versioning tools could help to manage parametric modelling complexity, as it has been showing with software counterparts. Four key features of version control: committing, differentiating, branching, and merging, and how they could be implemented in a parametric design practice are discussed. Initial user test sessions with 5 student designers using GHShot Grasshopper version control plugin (Cristie and Joyce 2018, 2017) revealed that the plugin is useful to record and overview design progression, share model, and provide a fallback mechanism.

GHShot: 3D Design Versioning for Learning and Collaboration in the Web

Abstract:
During the process of design, copies of files are often stored to track changes and design development or to ensure that previous work will not be lost. In software design field, such process is supported using versioning system, where source code is saved intermittently when features are added or modified for individual or group use. We argue that similar versioning system will also benefit the design community when applied to 3D design files, to see how their designs progress and collaborate. In this paper we outline a implemented web based open ecosystem allows designers to similarly collaborate but with a lower bar for adoption than comparable software versioning system. Our system is to be applied to a classroom setting, where architecture students learn to make structural designs; they are then able to see, modify, and give feedback to each other's work.

Exploring the Evolution of Meta Parametric Models

Abstract:
Parametric associative logic can describe complex design scenarios but are typically non-trivial and time consuming to develop. Optimization is being widely applied in many fields to find high-performing solutions to objective design needs, and this is being extended further to include user input to satisfy subjective preferences. However, whilst conventional optimization approaches can set good parameters for a model, they cannot currently improve the underlying logic defined by the associative topology of the model, leaving it limited to predefined domain of designs. This work looks at the application of Cartesian Genetic Programming (CGP) as a method for allowing the automatic generation, combination and modification of valid parametric models, including topology. This has value as it allows for a much greater range of solutions, and potentially computational "creativity," as it can develop unique and surprising solutions. However, the application of a genome-based definition and evolutionary optimization, respectively, to describe parametric models and develop better models for a problem, introduce many unknowns into the model generation process. This paper explains CGP as applied to parametric design and investigates the difference between using mating, mutating and both strategies together as a way of combining aspects of parent models, under selection by a genetic algorithm under random, objective and user (Interactive GA) preferences. We look into how this effects the resultant over iterated interaction in relation to both the geometry and the parametric model.

Connecting the dots: using Twitter for design insights into social behaviour around metro transport nodes in Singapore and beyond

Abstract:
There is increasing interest in understanding the use of urban space around heavily trafficked areas like transport interchanges; both in terms of their cultural social commercial use (Cha, 2001) but also in the context of ‘last mile’ journeys. However, this type of use is often not captured in traditional census, survey or transportation data. This research focuses on the use of social media data to develop insight into how spaces around public transportation stations are used in a comparative study of metro stations in several Asian cities. It focuses on finding similarities and differences between such spaces, including how different master planning and key urban amenities affect use. Specifically, this research aids in devising strategies to promote wider use and interconnectedness of area around stations and to understand the impact of large dense agglomerated building typologies, which are becoming a feature especially in Asian cities (Frampton et al., 2012).

Cloud Based Design Option Control Systems a Discussion and Implementation

Abstract:
The paper discusses a newly developed cloud based design-model version control system for supporting manual and semi-automated generative design via a web-based platform which enables exploration and retrieval of designs and the solicitation of users' evaluations of them to enable interactive genetic algorithms to produce preference optimised design options. The current needs of a commercial building engineering-design context is considered and relevant state-of-the-art computational design software is appraised, the review also covers software development based version-control-systems, identifying unmet needs in the former which could be solved by the latter which is the motivation for this work. A description of the new system's rational and current developmental architecture and technical components derived in response to these needs follows. Principal features include an online repository of design options, a parity between of users (human and machine) creating and acting upon the design options which align with existing tasks and processes undertaken by a design team. An example structural frame design problem is explored, discussing how the system functions to support performance based creative design via exploration, including visualisation and data dashboard of a design session. We discuss further work that could be undertaken to improve and widen the impact of this repository and collaborative human machine approach. We conclude that such systems addresses pressing software infrastructure requirements for the AEC industry especially for expanding the range of design options considered and managed particularly for early-stage design activities.

Ecological and Economic Concepts for a Mixed Initiative Networked Design Infrastructure

Abstract:
This paper describes the conceptual underpinnings of a infrastructure currently in development which aims to provide a computational environment for productive and creative human and computer co-creation of architectural design artefacts in an open, networked collaborative system. It identifies some key collaborative activities in design and looks to combine these within a system geared towards the productive utilisation of various agents involved towards developing a range of good design options. It takes as a conceptual foundation the application and hybridisation of evolutionary, ecological and economic principles. This approach is outlined with special emphasis on aligning with, and maximising the benefit of, an internet/network based infrastructure, connecting the design agents, supporting human/machine parity. The contribution for this paper is to assess the creative design context of the AEC industry, especially at early conceptual and ideation stages, and compare this against existing tools and paradigms used during creative design, to propose a new technological intervention to support these activities.

IJAC article - Generating freedom: questions of flexibility in digital design and architectural computation out now...

In response to the call for papers of the special edition of the International Journal of Architectural Computing entitled Design with Freedom we have written an article considering the flexibilities and limitations afforded by 'manual' design and prevalent computational design paradigms.

Abstract:
Generative processes and generative design approaches are topics of continuing interest and debate within the realms of architectural design and related fields. While they are often held up as giving designers the opportunity (the freedom) to explore far greater numbers of options/alternatives than would otherwise be possible, questions also arise regarding the limitations of such approaches on the design spaces explored, in comparison with more conventional, human-centric design processes. This article addresses the controversy with a specific focus on parametric-associative modelling and genetic programming methods of generative design. These represent two established contenders within the pool of procedural design approaches gaining increasingly wide acceptance in architectural computational research, education and practice. The two methods are compared and contrasted to highlight important differences in freedoms and limitations they afford, with respect to each other and to ‘manual’ design. We conclude that these methods may be combined with an appropriate balance of automation and human intervention to obtain ‘optimal’ design freedom, and we suggest steps towards finding that balance.

Thinking Topologically at Early Stage Parametric Design

Research into the use of parametric modelling in the creative and optimisation process. Limits are identified with respect to topological differentiation on the parametric models and thus the variation of the resultant models. Novel methods of increasing the topological variability are discussed in the cortex of early stage design along with it's implication.
