Presentation Notes

THE SOLUTION: DATA61 network AUSTRALIA’S DIGITAL INNOVATION POWERHOUSE Data61 is the only company with sufficient scale and reach to effect the change needed in the next 3-5 years to help Australia realise its digital, data-driven potential. We have a team of 1,146 staff, which includes 419 resident PhD students (plus summer scholars, visiting researchers and interns). We work with 31 Government partners, 91 Corporate partners, and 38 University partners. We are currently working on 193 data-driven projects, and we own 172 patents. Data61 is world leading in the domain of data-centric R&D and the early stages of commercialising data-centric solutions. And we are well placed to capture 0.1% of the Global R&D spend, across public and private sector, for both individual companies and industry sectors.

CSIRO Bracewell GPU Cluster6 |

• Bracewell consists of 114 PowerEdge C4130 servers hooked together with EDR InfiniBand.

• Aggregate memory across the entire system is 29 TB.

• Each server is equipped with four NVIDA P100 GPUs and two Intel Xeon 14-core CPUs.

• The GPUs alone represent over 2.4 petaflops of peak performance.

• Bracewell was installed over a period of just five days spanning the end of May and beginning of June 2017.

• The system came online in early July 2017

SNAP – Simulated Nanostructure Assembly using Proto-particles

SNAP9 |

Allows creation of user-defined nanoparticles, and subsequent Molecular Dynamics simulation to study aggregation.Nanoparticles are represented using a surface mesh, enabling researchers to define complex combinations of sizes, shape and facet combinations, each with specifically defined interactions.

GPU enabled to allow scaling to > 50,000 complex zonohedrons.

Includes tools for generating nanoparticle surface meshes and post simulation analysis.

Protecting Consumers by Legal/Ethical Means

“We address this issue by proposing a formal framework that can instantiate in agents’ dialogues moral/rational criteria, such as the maximin principle and impartiality, …e.g., by John Rawls’ theory or rule utilitarianism”.

Automatic Site Selection of Cultural Venues• A cGAN outputs zones from urban data as a constraint prior to a

stochastic optimisation of site locations of cultural venues.

Tian Feng & Tomasz Bednarz21 |

Automatic Site Selection of Cultural Venues• As cGANs can estimate appropriate zones for construction, the

search space is downsized and the optimiser quickly resolves issues like centralisation and lack of public access.

22 | Tian Feng & Tomasz Bednarz

Transport Network Synthesis• A cGAN is modified by replacing the binary classification function of the

discriminator with an energy-based function, and outputs functional transport networks from elevations and densities.

23 | Tian Feng & Tomasz Bednarz

Transport Network Synthesis• Instead of merely distinguishing real and fake examples, the energy-based

function aims to evaluate the traffic efficiency of a transport network using a traffic simulation model.

Presentation Notes

NetLogo-based simulation model takes five different weapons, respectively AEW&C (airborne early warning and control), jet (fighter), GBAD (ground based air defence), tank and Humvee. We collected specifications of main battle weapons used by ADF and thus applied them to NetLogo simulations.

Simulations - Properties• Weapon• Type (AEW&C, GBAD, Humvee, Jet, Tank), ID (e.g., 0, 1, 2), Colour (Blue, Red)• Coordinates (longitude, latitude, altitude), Heading, Speed• Number of sub-weapons (e.g., AGM88 for jets, AIM120 for jets and GBADs)• OnStation (only for AEW&Cs and jets), Target (only for jets)• Track• Tracker & trackee• Corresponding sensor and weapon ranges• Combat Network Adjacent Matrix• Perron-Febonius Eigenvalue (PFE)1

Presenter

Presentation Notes

Netlogo simulation outputs weapon properties, track information, and Perron-Febonius Eigenvalue per simulation tick. Perron-Febonius Eigenvalue (PFE) is calculated from the adjacent matrix from the real-time combat network of the simulation. It depicts the operational effectiveness (OE) of the target force. Generally speaking, larger the PFE, higher the OE. Operational effectiveness (OE) means performing similar activities better than rivals perform them. Operational effectiveness includes but is not limited to efficiency. It refers to any number of practices that allow a company to better utilise its inputs by, for example, reducing defects in products or developing better products faster. In contrast, strategic positioning means performing different activities from rivals’ or performing similar activities in different ways.”

Sensitivity Analysis• Regression Estimation2 of PFE and Win Probability

• y1 = PFE of Blue force, y2 = PFE of Red force, y3 = Win Probability of Blue force • x1 = no. of jets, x2 = no. of GBADs, x3 = no. of tanks and Humvees

Presentation Notes

By running NetLogo simulation for over 2000 times under various parameter settings, we trained a regression model to estimate PFE and Win Probablity.
