The paper introduces a lightweight neural network inspired by insect olfaction that classifies raw gas sensor readings using a sparse, high‑dimensional binary representation. It operates online, handling random sequences of single gases and binary mixtures, and dynamically incorporates new samples while providing class‑level frequency estimates to differentiate familiar from novel stimuli. The architecture, built with binary weights and Hebbian local learning, outperforms a linear SVM on mixtures, matches an optimized nonlinear SVM, and was demonstrated on the TEXEL neuromorphic chip with 74.6% accuracy, 482 nJ per inference, and 27 µW static power.

arXiv:2606. 24075v1 Announce Type: cross Abstract: Although deep learning-based methods can achieve high accuracy in automatic modulation recognition (AMR) tasks, their high computational cost makes it difficult to strike a balance between accuracy and power consumption, thereby limiting their application on resource-constrained platforms.

LDAC‑Net is a learnable multi‑lag differencing attention‑convolution network designed for drift‑robust recognition with low‑cost metal‑oxide (MOX) gas sensors. It replaces fixed first‑order temporal differencing with a front‑end that applies window‑conditioned statistical affine normalisation and learnable multi‑lag differencing, followed by an attention‑convolution backbone that captures both local transients and long‑range temporal dependencies. On the 50‑class SmellNet‑Base task, LDAC‑Net attains 68.2 % top‑1 accuracy, outperforming the best fixed‑lag model by about 14 percentage points and a raw‑input Transformer by over 30 points, and it also transfers well to other benchmarks such as SmellNet‑Mixtures and eNose‑Drift.

The paper explores how the number of bird species (target classes) affects the compressibility of neural networks for passive acoustic monitoring on microcontroller units (MCUs). By training and compressing models with varying class counts, the authors show that significant compression can be achieved with minimal performance loss. They also benchmark different hardware platforms and assess the feasibility of deploying energy‑autonomous monitoring devices.

The paper introduces an Embodied Neurocomputation framework that tackles the challenge of encoding and decoding between silicon computers and biological neural networks (BNNs). Using a large‑scale parameter sweep, the authors optimized over 1,300 encoding configurations for a BNN agent navigating an odor‑style gradient in a simulated grid‑world, running more than 4,000 hours of real‑time interactions. Twelve configurations consistently outperformed silicon‑based DQN agents within the same interaction budget, demonstrating the framework’s potential for scalable, goal‑oriented learning with BNNs.

The paper introduces a lightweight AI framework for vibration-based condition monitoring of consumer rotating devices. It transforms 1‑D vibration signals into 2‑D time‑frequency maps using continuous wavelet transform and Hilbert‑Huang transform, then applies compact deep learning models such as MobileNetV3‑Small, ConvNeXt‑Tiny, and YOLOv11‑cls. Experiments on public bearing datasets show that CWT with YOLOv11‑cls delivers high diagnostic accuracy, while MobileNetV3‑Small offers a low‑latency alternative suitable for edge deployment, and the study emphasizes the need to avoid data leakage in model evaluation.

Low-resolution infrared (IR) array sensors represent an interesting solution for privacy-preserving human sensing in embedded systems. In this letter, we describe a smart multi-pixel IR sensor integrating a 16$\times$16 thermal MOSFET (TMOS) array and a RISC-V microcontroller extended with low-precision SIMD instructions, capable of on-device learning and continual adaptation for pose and gesture recognition tasks under tight memory and power constraints ($<$32kB on-chip memory, $\approx$1.
