Latest 41 papers on energy efficiency: Feb. 14, 2026
The relentless march of AI and Machine Learning has brought unprecedented capabilities, but it’s also ushered in a silent, yet significant, challenge: energy consumption. From training colossal Large Language Models (LLMs) to deploying intelligent agents on tiny edge devices, the power footprint of modern AI is a growing concern. But fear not, innovation is surging! Recent research is tackling this challenge head-on, unveiling ingenious solutions that promise to make AI not just smarter, but dramatically greener and more sustainable.
The Big Idea(s) & Core Innovations
The central theme across these cutting-edge papers is a multi-faceted approach to energy efficiency, integrating hardware design, algorithmic optimization, and novel architectural paradigms. Researchers are reimagining everything from the fundamental building blocks of computation to the orchestration of complex distributed systems.
One significant thrust is in neuromorphic and optical computing, seeking to emulate the brain’s inherent efficiency. For instance, Anika Tabassum Meem et al. from the University of Liberal Arts Bangladesh and Pennsylvania State University introduce an energy-aware framework for continual learning in Spiking Neural Networks (SNNs) in their paper, “Energy-Aware Spike Budgeting for Continual Learning in Spiking Neural Networks for Neuromorphic Vision”. They demonstrate that explicitly using energy budgets as a control signal can improve accuracy while strategically managing spike activity to reduce dynamic power. Complementing this, Radib Bin Kabir et al. from Islamic University of Technology, Dhaka, and Southeast University, Dhaka, in “From Lightweight CNNs to SpikeNets: Benchmarking Accuracy-Energy Tradeoffs with Pruned Spiking SqueezeNet”, show that pruned spiking SqueezeNets can achieve near-CNN accuracy with an impressive 88.1% lower energy consumption, indicating that lightweight CNNs are inherently more compatible with energy-efficient spiking conversions. Further advancing neuromorphic efficiency, Chenyu Wang et al. from Sun Yat-sen University and National University of Singapore introduce Kirin in “Kirin: Improving ANN efficiency with SNN Hybridization”, a framework for lossless ANN-to-SNN conversion that achieves significant energy and latency reductions through integer-spike hybridization and a ‘Silence Threshold’ mechanism. On the optical front, Yingjie Li et al. present HoloGraph in “HoloGraph: All-Optical Graph Learning via Light Diffraction”, the first all-optical graph neural network that leverages light diffraction for energy-efficient message passing. This is echoed by Yi Zhang and Jingwen Li in “All-Optical Segmentation via Diffractive Neural Networks for Autonomous Driving”, who propose diffractive neural networks for real-time, energy-efficient scene understanding in autonomous vehicles.
Hardware acceleration and co-design are also critical. Chun-Hao Lin et al. from National Taiwan University unveil a high-utilization DNN accelerator in “A 16 nm 1.60TOPS/W High Utilization DNN Accelerator with 3D Spatial Data Reuse and Efficient Shared Memory Access” that achieves 1.60 TOPS/W through 3D spatial data reuse and shared memory optimization. In “Area-Efficient In-Memory Computing for Mixture-of-Experts via Multiplexing and Caching”, Ghyslain Giguère et al. from the University of Montreal and University of Science and Technology of China optimize in-memory computing for Mixture-of-Experts (MoE) models, achieving high performance density with reduced hardware area. Another breakthrough comes from Alessandro Pierro et al. from LMU Munich and Intel with “Evolutionary Mapping of Neural Networks to Spatial Accelerators”, an evolutionary framework that optimizes neural network deployment on spatial accelerators like Intel Loihi 2, showing up to 40% energy efficiency improvements. For LLM inference specifically, Author One and Author Two from the Institute of Advanced Computing and National Institute for AI Research introduce Harmonia in “Harmonia: Algorithm-Hardware Co-Design for Memory- and Compute-Efficient BFP-based LLM Inference”, significantly reducing memory and compute costs through an algorithm-hardware co-design approach. Even beyond traditional silicon, Alexander J. Edwards et al. from the Laboratory for Physical Sciences and The University of Texas at Dallas present “Magnetic Field-Mediated Superconducting Logic”, a novel superconducting switch that promises ultra-energy-efficient and scalable logic families by eliminating precision bias circuits and AC clocking.
Software-defined and system-level optimizations are also making huge strides. A. Aneggi et al. from the University of XYZ, Institute for Advanced Computing, and GreenTech Research Group introduce PPTAMη in “PPTAMη: Energy Aware CI/CD Pipeline for Container Based Applications”, an energy-aware CI/CD pipeline for containerized applications, integrating performance assessment with energy monitoring for sustainable cloud computing. For communication networks, M. Bordin et al. from Eurecom and the University of Bologna propose EExApp in “EExApp: GNN-Based Reinforcement Learning for Radio Unit Energy Optimization in 5G O-RAN”, using GNNs with reinforcement learning for 5G O-RAN energy optimization. Similarly, Author A and Author B from University X and Research Institute Y explore joint sleep mode activation and load balancing in “Joint Sleep Mode Activation and Load Balancing with Dynamic Cell Load: A Combinatorial Bandit Approach” for improved wireless network efficiency. Hiari Pizzini Cavagna et al. from the University of Bologna and Cineca delve into “Determining Energy Efficiency Sweet Spots in Production LLM Inference”, revealing that LLM inference has distinct ‘sweet spots’ for input/output lengths that can dramatically reduce energy consumption. Further, Haoyuan Zhu et al. from the University of Sheffield, Cambridge AI+ Ltd., and Ranplan Wireless Network Design Ltd. introduce the Degree of Information Abstraction (DIA) in “Information Abstraction for Data Transmission Networks based on Large Language Models”, enabling a 99.75% reduction in transmitted data volume for LLM-guided video transmission while preserving semantic fidelity.
