Energy
Sustainability via LLM Right-sizing
Haase, Jennifer, Klessascheck, Finn, Mendling, Jan, Pokutta, Sebastian
Large language models (LLMs) have become increasingly embedded in organizational workflows. This has raised concerns over their energy consumption, financial costs, and data sovereignty. While performance benchmarks often celebrate cutting-edge models, real-world deployment decisions require a broader perspective: when is a smaller, locally deployable model "good enough"? This study offers an empirical answer by evaluating eleven proprietary and open-weight LLMs across ten everyday occupational tasks, including summarizing texts, generating schedules, and drafting emails and proposals. Using a dual-LLM-based evaluation framework, we automated task execution and standardized evaluation across ten criteria related to output quality, factual accuracy, and ethical responsibility. Results show that GPT-4o delivers consistently superior performance but at a significantly higher cost and environmental footprint. Notably, smaller models like Gemma-3 and Phi-4 achieved strong and reliable results on most tasks, suggesting their viability in contexts requiring cost-efficiency, local deployment, or privacy. A cluster analysis revealed three model groups -- premium all-rounders, competent generalists, and limited but safe performers -- highlighting trade-offs between quality, control, and sustainability. Significantly, task type influenced model effectiveness: conceptual tasks challenged most models, while aggregation and transformation tasks yielded better performances. We argue for a shift from performance-maximizing benchmarks to task- and context-aware sufficiency assessments that better reflect organizational priorities. Our approach contributes a scalable method to evaluate AI models through a sustainability lens and offers actionable guidance for responsible LLM deployment in practice.
The best battery-powered doorbell camera is down to just 55 from 99 right now at Amazon
A few years ago, I hired an electrician to install a wired video doorbell in my house. He quoted me 1,500 because my house has a "unique" shape and it would require a lot of work to get wiring over there. The following week, I bought a battery-powered video doorbell for 99 and installed it myself in five minutes. You can live out this DIY smart home improvement scenario and save even more money by grabbing the Ring Battery Doorbell for just 55 right now at Amazon. This is the cheapest it has been since Black Friday last year, and a ton of other Ring accessories, including the excellent Floodlight Cam, are also on sale if you want to jump into an entire system.

Natural Policy Gradient for Average Reward Non-Stationary RL
Jali, Neharika, Pathak, Eshika, Sharma, Pranay, Qu, Guannan, Joshi, Gauri
We consider the problem of non-stationary reinforcement learning (RL) in the infinite-horizon average-reward setting. We model it by a Markov Decision Process with time-varying rewards and transition probabilities, with a variation budget of $\Delta_T$. Existing non-stationary RL algorithms focus on model-based and model-free value-based methods. Policy-based methods despite their flexibility in practice are not theoretically well understood in non-stationary RL. We propose and analyze the first model-free policy-based algorithm, Non-Stationary Natural Actor-Critic (NS-NAC), a policy gradient method with a restart based exploration for change and a novel interpretation of learning rates as adapting factors. Further, we present a bandit-over-RL based parameter-free algorithm BORL-NS-NAC that does not require prior knowledge of the variation budget $\Delta_T$. We present a dynamic regret of $\tilde{\mathscr O}(|S|^{1/2}|A|^{1/2}\Delta_T^{1/6}T^{5/6})$ for both algorithms, where $T$ is the time horizon, and $|S|$, $|A|$ are the sizes of the state and action spaces. The regret analysis leverages a novel adaptation of the Lyapunov function analysis of NAC to dynamic environments and characterizes the effects of simultaneous updates in policy, value function estimate and changes in the environment.
High-performance training and inference for deep equivariant interatomic potentials
Tan, Chuin Wei, Descoteaux, Marc L., Kotak, Mit, Nascimento, Gabriel de Miranda, Kavanagh, Seรกn R., Zichi, Laura, Wang, Menghang, Saluja, Aadit, Hu, Yizhong R., Smidt, Tess, Johansson, Anders, Witt, William C., Kozinsky, Boris, Musaelian, Albert
Machine learning interatomic potentials, particularly those based on deep equivariant neural networks, have demonstrated state-of-the-art accuracy and computational efficiency in atomistic modeling tasks like molecular dynamics and high-throughput screening. The size of datasets and demands of downstream workflows are growing rapidly, making robust and scalable software essential. This work presents a major overhaul of the NequIP framework focusing on multi-node parallelism, computational performance, and extensibility. The redesigned framework supports distributed training on large datasets and removes barriers preventing full utilization of the PyTorch 2.0 compiler at train time. We demonstrate this acceleration in a case study by training Allegro models on the SPICE 2 dataset of organic molecular systems. For inference, we introduce the first end-to-end infrastructure that uses the PyTorch Ahead-of-Time Inductor compiler for machine learning interatomic potentials. Additionally, we implement a custom kernel for the Allegro model's most expensive operation, the tensor product. Together, these advancements speed up molecular dynamics calculations on system sizes of practical relevance by up to a factor of 18.
Hessian Riemannian Flow For Multi-Population Wardrop Equilibrium
Bakaryan, Tigran, Aoun, Christoph, Ribeiro, Ricardo de Lima, Hovakimyan, Naira, Gomes, Diogo
Abstract-- In this paper, we address the problem of optimizing flows on generalized graphs that feature multiple entry points and multiple populations, each with varying co st structures. We tackle this problem by considering the multi - population Wardrop equilibrium, defined through variation al inequalities. We rigorously analyze the existence and uniq ueness of the Wardrop equilibrium. Furthermore, we introduce an efficient numerical method to find the solution. In particula r, we reformulate the equilibrium problem as a distributed optimization problem over subgraphs and introduce a novel Hessian Riemannian flow method--a Riemannian-manifold-projected Hessian flow--to efficiently compute a solution. Fi - nally, we demonstrate the effectiveness of our approach thr ough examples in urban traffic management, including routing for diverse vehicle types and strategies for minimizing emissi ons in congested environments. In traffic management, each driver--whether operating a car, SUV, or truck--selects the route they perceive to be the shortest.
Adversarial Observations in Weather Forecasting
Imgrund, Erik, Eisenhofer, Thorsten, Rieck, Konrad
AI-based systems, such as Google's GenCast, have recently redefined the state of the art in weather forecasting, offering more accurate and timely predictions of both everyday weather and extreme events. While these systems are on the verge of replacing traditional meteorological methods, they also introduce new vulnerabilities into the forecasting process. In this paper, we investigate this threat and present a novel attack on autoregressive diffusion models, such as those used in GenCast, capable of manipulating weather forecasts and fabricating extreme events, including hurricanes, heat waves, and intense rainfall. The attack introduces subtle perturbations into weather observations that are statistically indistinguishable from natural noise and change less than 0.1% of the measurements - comparable to tampering with data from a single meteorological satellite. As modern forecasting integrates data from nearly a hundred satellites and many other sources operated by different countries, our findings highlight a critical security risk with the potential to cause large-scale disruptions and undermine public trust in weather prediction.
Trustworthy Decentralized Autonomous Machines: A New Paradigm in Automation Economy
Castillo, Fernando, Castillo, Oscar, Brito, Eduardo, Espinola, Simon
Decentralized Autonomous Machines (DAMs) represent a transformative paradigm in automation economy, integrating artificial intelligence (AI), blockchain technology, and Internet of Things (IoT) devices to create self-governing economic agents participating in Decentralized Physical Infrastructure Networks (DePIN). Capable of managing both digital and physical assets and unlike traditional Decentralized Autonomous Organizations (DAOs), DAMs extend autonomy into the physical world, enabling trustless systems for Real and Digital World Assets (RDWAs). In this paper, we explore the technological foundations, and challenges of DAMs and argue that DAMs are pivotal in transitioning from trust-based to trustless economic models, offering scalable, transparent, and equitable solutions for asset management. The integration of AI-driven decision-making, IoT-enabled operational autonomy, and blockchain-based governance allows DAMs to decentralize ownership, optimize resource allocation, and democratize access to economic opportunities. Therefore, in this research, we highlight the potential of DAMs to address inefficiencies in centralized systems, reduce wealth disparities, and foster a post-labor economy.
Multi-Modal Fusion of In-Situ Video Data and Process Parameters for Online Forecasting of Cookie Drying Readiness
Food drying is essential for food production, extending shelf life, and reducing transportation costs. Accurate real-time forecasting of drying readiness is crucial for minimizing energy consumption, improving productivity, and ensuring product quality. However, this remains challenging due to the dynamic nature of drying, limited data availability, and the lack of effective predictive analytical methods. To address this gap, we propose an end-to-end multi-modal data fusion framework that integrates in-situ video data with process parameters for real-time food drying readiness forecasting. Our approach leverages a new encoder-decoder architecture with modality-specific encoders and a transformer-based decoder to effectively extract features while preserving the unique structure of each modality. We apply our approach to sugar cookie drying, where time-to-ready is predicted at each timestamp. Experimental results demonstrate that our model achieves an average prediction error of only 15 seconds, outperforming state-of-the-art data fusion methods by 65.69% and a video-only model by 11.30%. The proposed model is extensible to various other industrial modality fusion tasks for online decision-making. Introduction Drying is a fundamental process in the food industry that plays a critical role in both food production and preservation. By removing moisture, it transforms raw ingredients into their final, consumable forms while enhancing texture, flavor, and structural integrity [1]. However, food drying is a highly time-and energy-intensive process which accounts for 15% of energy consumption in U.S. industrial processes [2]. As a result, advancing drying technologies and improving product quality are key strategies for minimizing waste and enhancing energy efficiency [3].
Real-Time Optimal Design of Experiment for Parameter Identification of Li-Ion Cell Electrochemical Model
Mikesell, Ian, da Silva, Samuel Filgueira, Ozkan, Mehmet Fatih, Idrissi, Faissal El, Ramesh, Prashanth, Canova, Marcello
Abstract: Accurately identifying the parameters of electrochemical models of li-ion battery (LiB) cells is a critical task for enhancing the fidelity and predictive ability. Traditional parameter identification methods often require extensive data collection experiments and lack adaptability in dynamic environments. This paper describes a Reinforcement Learning (RL) based approach that dynamically tailors the current profile applied to a LiB cell to optimize the parameters identifiability of the electrochemical model. The proposed framework is implemented in real-time using a Hardware-in-the-Loop (HIL) setup, which serves as a reliable testbed for evaluating the RL-based design strategy. The HIL validation confirms that the RL-based experimental design outperforms conventional test protocols used for parameter identification in terms of both reducing the modeling errors on a verification test and minimizing the duration of the experiment used for parameter identification.
