«This can be immensely empowering, and can improve public trust: it’s hard (and unwise) to give yourself over to a technology that won’t tell you how it works, particularly when its predefined settings allow only for meagre approaches to “user privacy”. As I ask my students, if you could develop an AI at your own home, and programme it to reflect your values and prioritise your safety, wouldn’t you trust it more? Well, the idea isn’t so outlandish – it only feels impossible because big tech fir…

TransLink’s PrideBus returns in playful 16-bit style
Extra SkyTrain service and bus detours on Sunday for Pride Parade
TransLink’s iconic PrideBus will be featured in the 47th annual Vancouver Pride Parade on Sunday, August 3. TransLink staff will also be marching alongside the PrideBus to celebrate the 2SLGBTQIA communities.

- I found my love in Portofino / Dalida
I found my love in Portofino
Perché nei sogni credo ancor
Lo strano gioco del destino
A Portofino m'ha preso il cuor

Nel dolce incanto del mattino
Il mare ti ha portato a me
Socchiudo gli occhi e a me vicino
A Portofino rivedo te
Ricordo un angolo di cielo
Dove ti stavo ad aspettar
Ricordo il volto tanto amato
E la tua bocca da baciar

The Triangle Friendship Paradox
We consider the generalised friendship paradox, focussing on the number of triangles at a vertex as the relevant attribute. We show that, contrary to the setting where the attribute is the number of edges at a vertex or the number of wedges at a vertex, the average friendship-bias of the number of triangles at a vertex is not always non-negative. We identify classes of finite deterministic graphs for which the bias is non-negative, and provide examples of finite deterministic graphs for which i…

I'm making my SmartHome dumb again.
I got rid of my Google Assistants, smart lights, and plugs, and switched to LED bulbs to save energy. On top of this, I got a portable solar panel to charge my small devices.
For the evening, I now have a USB rechargeable LED light.
I’m doing this to reduce the cost of my electricity bill. Plus, it’s a good way to get rid of big tech products.

End-to-End Large Portfolio Optimization for Variance Minimization with Neural Networks through Covariance Cleaning
We develop a rotation-invariant neural network that provides the global minimum-variance portfolio by jointly learning how to lag-transform historical returns and how to regularise both the eigenvalues and the marginal volatilities of large equity covariance matrices. This explicit mathematical mapping offers clear interpretability of each module's role, so the model cannot be regarded as a pure black-box. The architecture mirrors the analytical form of the global minimum-variance solution yet …

Neuro-Informed Joint Learning Enhances Cognitive Workload Decoding in Portable BCIs
Portable and wearable consumer-grade electroencephalography (EEG) devices, like Muse headbands, offer unprecedented mobility for daily brain-computer interface (BCI) applications, including cognitive load detection. However, the exacerbated non-stationarity in portable EEG signals constrains data fidelity and decoding accuracy, creating a fundamental trade-off between portability and performance. To mitigate such limitation, we propose MuseCogNet (Muse-based Cognitive Network), a unified joint …

The Hybrid Renewable Energy Forecasting and Trading Competition 2024
The Hybrid Energy Forecasting and Trading Competition challenged participants to forecast and trade the electricity generation from a 3.6GW portfolio of wind and solar farms in Great Britain for three months in 2024. The competition mimicked operational practice with participants required to submit genuine forecasts and market bids for the day-ahead on a daily basis. Prizes were awarded for forecasting performance measured by Pinball Score, trading performance measured by total revenue, and com…
