Detection and prediction of the onset of seizures are among the most challenging problems in epilepsy diagnostics and treatment. Small electronic devices capable of doing that will improve the quality of life for epilepsy patients while also open new opportunities for pharmacological intervention. This paper presents a novel approach using machine learning techniques to detect seizures onset using electroencephalography (EEG) signals. The proposed approach was tested on EEG data recorded in rats with pilocarpine model of temporal lobe epilepsy. A principal component analysis was applied for feature selection before using a support vector machine for the detection of seizures. Hjorth's parameters and Daubechies discrete wavelet transform coefficients were found to be the most informative features of EEG data. We found that the support vector machine approach had a classification sensitivity of 90% and a specificity of 74% for detecting ictal episodes. Changing the epoch parameter from one to twenty-one seconds results in changing the redistribution of principal components’ values to 10% but does not affect the classification result. Support vector machines are accessible and convenient methods for classification that have achieved promising classification quality, and are rather lightweight compared to other machine learning methods. So we suggest their future use in mobile devices for early epileptic seizure and preictal episodes detection.

(33) Interference Minimization in Beyond-Diagonal RIS-assisted MIMO Interference Channels
I. Santamaria, M. Soleymani, E. Jorswieck, J. Gutiérrez Teran
IEEE Open Journal of Vehicular Technology 6, 1005 (2025)
DOI: 10.1109/OJVT.2025.3555425, (6G-SENSES)
This paper proposes a two-stage approach for passive and active beamforming in multiple-input multiple-output (MIMO) interference channels (ICs) assisted by a beyond-diagonal reconfigurable intelligent surface (BD-RIS). In the first stage, the passive BD-RIS is designed to minimize the aggregate interference power at all receivers, a cost function called interference leakage (IL). To this end, we propose an optimization algorithm in the manifold of unitary matrices and a suboptimal but computationally efficient solution. In the second stage, users' active precoders are designed under different criteria such as minimizing the IL (min-IL), maximizing the signal-to-interference-plus-noise ratio (max-SINR), or maximizing the sum rate (max-SR). The residual interference not cancelled by the BD-RIS is treated as noise by the precoders. Our simulation results show that the max-SR precoders provide more than 20% sum rate improvement compared to other designs, especially when the BD-RIS has a moderate number of elements (M<20) and users transmit with high power, in which case the residual interference is still significant.

DOI: 10.1016/j.microrel.2025.115630, (6G-RIC)
The in-memory computing (IMC) systems based on emerging technologies have gained significant attention due to their potential to enhance performance and energy efficiency by minimizing data movement between memory and processing unit, which is especially beneficial for data-intensive applications. Designing and evaluating systems utilizing emerging memory technologies, such as resistive RAM (RRAM), poses considerable challenges due to the limited support from electronics design automation (EDA) tools for rapid development and design space exploration. Additionally, incorporating technology-dependent variability into system-level simulations is critical to accurately assess the impact on system reliability and performance. To bridge this gap, we propose RRAMulator, a field-programmable gate array (FPGA) based hardware emulator for RRAM crossbar array. To avoid the complex device models capturing the nonlinear current–voltage (IV) relationships that degrade emulation speed and increase hardware utilization, we propose a device and variability modeling approach based on device measurements. We deploy look-up tables (LUTs) for device modeling and use the multivariate kernel density estimation (KDE) method to augment existing data, extending data variety and avoiding repetitive data usage. The proposed emulator achieves cycle-accurate, real-time emulations and provides information such as latency and energy consumption for matrix mapping and vector–matrix multiplications (VMMs). Experimental results show a significant reduction in emulation time compared to conventional behavioral simulations. Additionally, an RRAM-based discrete Fourier transform (DFT) accelerator is analyzed as a case study featuring a range of in-depth system assessments.
(42) ImSTDP: Implicit Timing On-Chip STDP Learning

DOI: 10.1109/TCSI.2024.3450958
Spike-Timing-Dependent Plasticity (STDP) is a biological-plausible learning mechanism widely adopted for building Spiking Neural Networks (SNNs). It determines plasticity polarity and synapse strength change according to the timing difference between pre-and postsynaptic spikes. The learning curves of STDP differ in temporal window size, magnitude and polarity across different synapse types and brain regions and even within a cell, in different dendritic compartments. To accelerate on-chip STDP learning, various implementations have been proposed. However, they either introduce significant latency due to costly counter-based time difference calculation and substantial area cost due to the implementation of weight change LUTs, or lose biologically-plausible timing information due to oversimplification. For low-cost and efficient on-chip learning, a high-throughput Implicit-timing STDP (ImSTDP) with optimized SR depth and a low-cost register-based Implicit-Timing Look-up (ITL) are proposed. ASIC implementation in 22 nm technology demonstrates that ImSTDP can achieve up to 2 × throughput improvement and 3.61 × power efficiency improvement at 27% less area cost compared to the cutting-edge counter-LUT on-chip STDP learning solution.

Detection and prediction of the onset of seizures are among the most challenging problems in epilepsy diagnostics and treatment. Small electronic devices capable of doing that will improve the quality of life for epilepsy patients while also open new opportunities for pharmacological intervention. This paper presents a novel approach using machine learning techniques to detect seizures onset using electroencephalography (EEG) signals. The proposed approach was tested on EEG data recorded in rats with pilocarpine model of temporal lobe epilepsy. A principal component analysis was applied for feature selection before using a support vector machine for the detection of seizures. Hjorth's parameters and Daubechies discrete wavelet transform coefficients were found to be the most informative features of EEG data. We found that the support vector machine approach had a classification sensitivity of 90% and a specificity of 74% for detecting ictal episodes. Changing the epoch parameter from one to twenty-one seconds results in changing the redistribution of principal components’ values to 10% but does not affect the classification result. Support vector machines are accessible and convenient methods for classification that have achieved promising classification quality, and are rather lightweight compared to other machine learning methods. So we suggest their future use in mobile devices for early epileptic seizure and preictal episodes detection.

This paper proposes a two-stage approach for passive and active beamforming in multiple-input multiple-output (MIMO) interference channels (ICs) assisted by a beyond-diagonal reconfigurable intelligent surface (BD-RIS). In the first stage, the passive BD-RIS is designed to minimize the aggregate interference power at all receivers, a cost function called interference leakage (IL). To this end, we propose an optimization algorithm in the manifold of unitary matrices and a suboptimal but computationally efficient solution. In the second stage, users' active precoders are designed under different criteria such as minimizing the IL (min-IL), maximizing the signal-to-interference-plus-noise ratio (max-SINR), or maximizing the sum rate (max-SR). The residual interference not cancelled by the BD-RIS is treated as noise by the precoders. Our simulation results show that the max-SR precoders provide more than 20% sum rate improvement compared to other designs, especially when the BD-RIS has a moderate number of elements (M<20) and users transmit with high power, in which case the residual interference is still significant.

The in-memory computing (IMC) systems based on emerging technologies have gained significant attention due to their potential to enhance performance and energy efficiency by minimizing data movement between memory and processing unit, which is especially beneficial for data-intensive applications. Designing and evaluating systems utilizing emerging memory technologies, such as resistive RAM (RRAM), poses considerable challenges due to the limited support from electronics design automation (EDA) tools for rapid development and design space exploration. Additionally, incorporating technology-dependent variability into system-level simulations is critical to accurately assess the impact on system reliability and performance. To bridge this gap, we propose RRAMulator, a field-programmable gate array (FPGA) based hardware emulator for RRAM crossbar array. To avoid the complex device models capturing the nonlinear current–voltage (IV) relationships that degrade emulation speed and increase hardware utilization, we propose a device and variability modeling approach based on device measurements. We deploy look-up tables (LUTs) for device modeling and use the multivariate kernel density estimation (KDE) method to augment existing data, extending data variety and avoiding repetitive data usage. The proposed emulator achieves cycle-accurate, real-time emulations and provides information such as latency and energy consumption for matrix mapping and vector–matrix multiplications (VMMs). Experimental results show a significant reduction in emulation time compared to conventional behavioral simulations. Additionally, an RRAM-based discrete Fourier transform (DFT) accelerator is analyzed as a case study featuring a range of in-depth system assessments.

Spike-Timing-Dependent Plasticity (STDP) is a biological-plausible learning mechanism widely adopted for building Spiking Neural Networks (SNNs). It determines plasticity polarity and synapse strength change according to the timing difference between pre-and postsynaptic spikes. The learning curves of STDP differ in temporal window size, magnitude and polarity across different synapse types and brain regions and even within a cell, in different dendritic compartments. To accelerate on-chip STDP learning, various implementations have been proposed. However, they either introduce significant latency due to costly counter-based time difference calculation and substantial area cost due to the implementation of weight change LUTs, or lose biologically-plausible timing information due to oversimplification. For low-cost and efficient on-chip learning, a high-throughput Implicit-timing STDP (ImSTDP) with optimized SR depth and a low-cost register-based Implicit-Timing Look-up (ITL) are proposed. ASIC implementation in 22 nm technology demonstrates that ImSTDP can achieve up to 2 × throughput improvement and 3.61 × power efficiency improvement at 27% less area cost compared to the cutting-edge counter-LUT on-chip STDP learning solution.
