Combining Cloud and Mobile Computing for Machine Learning
Although the computing power of mobile devices is increasing, machine learning models are also growing in size. This trend creates problems for mobile devices due to limitations like their memory capacity and battery life. While many services, like ChatGPT and Midjourney, run all the inferences in the cloud, we believe a flexible and fine-grained task distribution is more desirable.

Investigating White-Box Attacks for On-Device Models
Numerous mobile apps have leveraged deep learning capabilities. However, on-device models are vulnerable to attacks as they can be easily extracted from their corresponding mobile apps. Existing on-device attacking approaches only generate black-box attacks, which are far less effective and efficient than white-box strategies. This is because mobile deep learning frameworks like TFLite do not support gradient computing, which is necessary for white-box attacking algorithms. Thus, we argue that …

I've recently finished the book "Flying Blind: The 737 MAX Tragedy and the Fall of Boeing", and it was actually pretty depressing to read how a focus on pure "shareholder value" and private enrichment of executives can quickly destroy most of the value of one of the biggest and highly innovative companies. Reading about the destruction of technical excellence in favor of a race to the bottom for short term market gains should be a cautionary tale for all companies that are currently technical leaders. Learn from history how easily that can change.
PS: Now that I know more about the behind-the-scenes reasons for the 737 Max accidents and resulting deaths, I will personally avoid flying in any of them in particular, and generally try to stay away from Boing aircraft while the company is further slipping into even shoddier QA practices.

I have a brief story to tell: Earlier this week, a large DDoS attack against 2 out of our larger set of #Tor (@…) relays - which also act as stable HSDir nodes - has managed to partially interrupt Internet traffic for the whole #JKULinz. While the attack was not huge compared to others (peak traffic around 3-4 Gbit/s, well above 1M PPS), we suspect either a nation state actor or fairly well-funded organization for 3 reasons:
* The attack was more advanced than simply saturating the upstream with bandwidth/packets, but had proper handshakes with the Tor relays, trying to cause resource exhaustion on the application level (we have seen this pattern multiple times in the last 6 months, but this one was much more massive in terms of incoming packets).
* The attack was very targeted, affecting only 2 IPs out of 25, consistently over some time. This indicates that either the position in the HSDir or specific connections or hidden services that were relayed over those nodes were the target - but note that these are only guesses, we don't have hard data on the motivation of this targeting.
* The only motivations that come to mind are either de-anonymization attacks or take-downs of particular hidden services. These do not seem to be relevant for usual ransom DDoS botnet attackers, but more for political reasons.
We have some flow data and would be interested in doing more analysis. Any ideas or correlation with other data on Tor relay attacks welcome :)

SHINE: Social Homology Identification for Navigation in Crowded Environments
Navigating mobile robots in social environments remains a challenging task due to the intricacies of human-robot interactions. Most of the motion planners designed for crowded and dynamic environments focus on choosing the best velocity to reach the goal while avoiding collisions, but do not explicitly consider the high-level navigation behavior (avoiding through the left or right side, letting others pass or passing before others, etc.). In this work, we present a novel motion planner that inc…

Integrated Sensing and Communications with Affine Frequency Division Multiplexing
Integrated sensing and communications (ISAC) is regarded as a key technology in next-generation (6G) mobile communication systems. Affine frequency division multiplexing (AFDM) is a recently proposed waveform that achieves optimal diversity gain in high mobility scenarios and has appealing properties in high-frequency communication. In this letter, we present an AFDM-based ISAC system. We first show that in order to identify all delay and Doppler components associated with the propagation mediu…

Task Graph offloading via Deep Reinforcement Learning in Mobile Edge Computing
Various mobile applications that comprise dependent tasks are gaining widespread popularity and are increasingly complex. These applications often have low-latency requirements, resulting in a significant surge in demand for computing resources. With the emergence of mobile edge computing (MEC), it becomes the most significant issue to offload the application tasks onto small-scale devices deployed at the edge of the mobile network for obtaining a high-quality user experience. However, since th…

Note that we strongly suspect the interruption of university traffic to have been collateral damage, and not the target of the attack. All indicators point to the two specific @… relays to have been the real target. Funnily enough, one of them was automatically restarted because of resource exhaustion, and otherwise the relays kept working.
We also know why the collateral outage happened, but first want to analyze it further and potentially talk to the network device vendor before I can publicly release more details. There may be a coordinated disclosure process in our near term future...

Diagrammatic Instructions to Specify Spatial Objectives and Constraints with Applications to Mobile Base Placement
This paper introduces Spatial Diagrammatic Instructions (SDIs), an approach for human operators to specify objectives and constraints that are related to spatial regions in the working environment. Human operators are enabled to sketch out regions directly on camera images that correspond to the objectives and constraints. These sketches are projected to 3D spatial coordinates, and continuous Spatial Instruction Maps (SIMs) are learned upon them. These maps can then be integrated into optimizat…

An Accurate Beam-Tracking Algorithm with Adaptive Beam Reconstruction via UAV-BSs for Mobile Users
Unmanned aerial vehicles (UAVs) with flexible deployment contribute to enlarging the distance of information transmission to mobile users (MUs) in constrained environment. However, due to the high mobility of both UAVs and MUs, it is challenging to establish an accurate beam towards the target MU with high beam gain in real-time. In this study, UAV base stations (UAV-BSs) consisting of position-known assisted UAVs (A-UAVs) and position-unknown assisted UAVs (U-UAVs) are employed to transmit dat…

Theoretical Analysis of the Radio Map Estimation Problem
Radio maps provide radio frequency metrics, such as the received signal strength, at every location of a geographic area. These maps, which are estimated using a set of measurements collected at multiple positions, find a wide range of applications in wireless communications, including the prediction of coverage holes, network planning, resource allocation, and path planning for mobile robots. Although a vast number of estimators have been proposed, the theoretical understanding of the radio ma…

Resilient source seeking with robot swarms
We present a solution for locating the source, or maximum, of an unknown scalar field using a swarm of mobile robots. Unlike relying on the traditional gradient information, the swarm determines an ascending direction to approach the source with arbitrary precision. The ascending direction is calculated from measurements of the field strength at the robot locations and their relative positions concerning the centroid. Rather than focusing on individual robots, we focus the analysis on the densi…

SeSaMe: A Framework to Simulate Self-Reported Ground Truth for Mental Health Sensing Studies
Advances in mobile and wearable technologies have enabled the potential to passively monitor a person's mental, behavioral, and affective health. These approaches typically rely on longitudinal collection of self-reported outcomes, e.g., depression, stress, and anxiety, to train machine learning (ML) models. However, the need to continuously self-report adds a significant burden on the participants, often resulting in attrition, missing labels, or insincere responses. In this work, we introduce…

Conformal Temporal Logic Planning using Large Language Models
This paper addresses a new motion planning problem for mobile robots tasked with accomplishing multiple high-level sub-tasks, expressed using natural language (NL). These sub-tasks should be accomplished in a temporal and logical order. To formally define the overarching mission, we leverage Linear Temporal Logic (LTL) defined over atomic predicates modeling these NL-based sub-tasks. This is in contrast to related planning approaches that define LTL tasks over atomic predicates capturing desire…
