Earlier this year, I noticed something in China that really surprised me.  I realized I felt more comfortable discussing controversial ideas in Beijing than in San Francisco.  I didn’t feel completely comfortable—this was China, after all—just more comfortable than at home. That showed me just how bad things have become, and how much things have changed since I first got started here in 2005. It seems easier to accidentally speak heresies in San Francisco every year.  Debating a […]

arXiv:2402.13662v3 Announce Type: replace-cross Abstract: We present a method for upper and lower bounding the right and the left tail probabilities of continuous random variables (RVs). For the right tail probability of RV $X$ with probability density function $f (x)$, this method requires first setting a continuous, positive, and strictly decreasing function $g (x)$ such that $-f (x)/g’ (x)$ is a decreasing and increasing function, $forall x>x_0$, which results in upper and lower bounds, respectively, given in the […]

The widespread deployment of 5G networks, together with the coexistence of 4G/LTE networks, provides mobile devices a diverse set of candidate cells to connect to. However, associating mobile devices to cells to maximize overall network performance, a.k.a. cell (re)selection, remains a key challenge for mobile operators. Today, cell (re)selection parameters are typically configured manually based on operator experience and rarely adapted to dynamic network conditions. In this work, we ask: Can an agent automatically learn and adapt cell […]

arXiv:2601.05483v1 Announce Type: new Abstract: Understanding urban environment change is essential for sustainable development. However, current approaches, particularly remote sensing change detection, often rely on rigid, single-modal analysis. To overcome these limitations, we propose MMUEChange, a multi-modal agent framework that flexibly integrates heterogeneous urban data via a modular toolkit and a core module, Modality Controller for cross- and intra-modal alignment, enabling robust analysis of complex urban change scenarios. Case studies include: a shift toward small, community-focused parks in […]

Body (unchanged, already compliant): If you just got an RTX 5090 / 5080 / 5070 and CuPy (or downstream libraries) is failing, this is why. TL;DR Blackwell GPUs require CUDA 13.1 Pre-built CuPy wheels do not support compute capability 10.0 You must build from source CuPy setup pip uninstall cupy cupy-cuda12x -y Install CUDA Toolkit 13.1, then: pip install cupy –no-binary cupy Windows note: Add the following to PATH: C:Program FilesNVIDIA GPU Computing ToolkitCUDAv13.1binx64 DLLs are not in […]

arXiv:2601.02526v1 Announce Type: new Abstract: This work presents a microscopic model to describe pedestrian flows based on the social force theory. The aim of this study is twofold: (1) developing a realistic model that can be used as a tool for designing pedestrian-friendly infrastructure, and (2) verifying a social science theory using a model with sufficient data. The investigation of the pedestrian model shows that despite simple individual behavior patterns, complex spatial and temporal structures emerge through the […]

arXiv:2601.00156v1 Announce Type: new Abstract: In this paper, we introduce an underexplored problem in facial analysis: generating and recognizing multi-attribute natural language descriptions, containing facial action units (AUs), emotional states, and age estimation, for arbitrarily selected face regions (termed FaceFocalDesc). We argue that the system’s ability to focus on individual facial areas leads to better understanding and control. To achieve this capability, we construct a new multi-attribute description dataset for arbitrarily selected face regions, providing rich region-level annotations […]

For a few weeks now I have been working on a new idea: an autonomous robot photographer. My ultimate goal is to build a fully autonomous robot which could take well-composed pictures in various social events: conferences, open days, weddings and so on. In the process I am also hoping to build a scalable system that could be extended to more complicated tasks and, potentially, used as a teaching tool at an undergraduate level. I am planning to […]
