SUMMARY:Internet of Things-Based Collaborative Position-Sensing Systems for Cardiopulmonary Resuscitation and Indoor Localization
DESCRIPTION:Name: Chen\, Hsin-Chung “Andrew” \nChair: Pai Chou \nDate:  Wednesday\, March 16\, 2022 \nTime: 9:00 am \nLocation:  https://uci.zoom.us/j/93264053012 \nCommittee: Nader Bagherzadeh\, Rainer Doemer \nTitle: Internet of Things-Based Collaborative Position-Sensing Systems for Cardiopulmonary Resuscitation and Indoor Localization \nAbstract: \nThe ubiquitous IoT devices have promoted the growth of applications that require target positioning. While precise positioning remains a challenge for IoT devices\, existing methods mainly focus on optimizing the positioning algorithms or expanding the sensing modalities. One opportunity area of improvement is to leverage their wireless communication capability to exchange sensing data of different modalities with nearby devices. This work proposes collaborative sensing frameworks to enhance the accuracy of position inference. \nOur approach to collaborative sensing is divided into selection of reliable devices\, the data-exchange mechanism\, and the data-fusion algorithm. We demonstrate our approach on two different position-sensing systems: one for chest compression-depth estimation and one for indoor pedestrian localization. The key components used in the frameworks include quality assessment of sensor data using mutual information\, data-fusion algorithms based on the chest-compression model and the pedestrian-encounter model\, and the data-exchange mechanism using Bluetooth Low Energy (BLE). A real-time position-estimation method based on our chest-compression model is proposed to remove the noise and handle the cumulative error. A collaborative conditional random field algorithm is developed to reduce the convergence distance in the localization estimation. Experimental results show our collaborative-sensing approach outperforms the existing solutions in terms of real-time estimated position. \nThis dissertation proposes an alternative approach to optimizing the position-sensing systems through collaborative sensing. Our work represents the first step towards the universal positioning on IoT devices and provides research opportunities for further improvement and exploration. \n\nShort Bio: Hsinchung Chen is a Ph.D. candidate in computer engineering. His research interests include signal processing\, machine learning\, and embedded system design.

SUMMARY:Advancing Compiler and Simulator Techniques for Highly Parallel Simulation of Embedded Systems
DESCRIPTION:Name: Zhongqi Cheng\nChair: Prof. Rainer Doemer \nDate: May 29th\, 2020 \nTime: 02:00 PM \nLocation:  Zoom \nCommittee: Rainer Doemer (Chair)\, Prof. Mohammad Al Faruque and Prof. Aparna Chandramowlishwaran \nTitle: “Advancing Compiler and Simulator Techniques for Highly Parallel Simulation of Embedded Systems” \nAbstract: \nAs an Electronic System Level (ESL) design language\, the IEEE SystemC standard is widely used for testing\, validation and verification of embedded system models. Discrete Event Simulation (DES) has been used for decades as the default SystemC simulation semantic. However\, due to the sequential nature of DES\, Parallel DES has recently gained an increasing amount of attention for performing high speed simulations on parallel computing platforms. To further exploit the parallel computation power of modern multi- and many-core platforms\, Out-of-order Parallel Discrete Event Simulation (OoO PDES) has been proposed. In OoO PDES\, threads comply with a partial order such that different simulation threads may run in different time cycles to increase the parallelism of execution. The Recoding Infrastructure for SystemC (RISC) has been introduced as a tool flow to fully support OoO PDES. \nTo preserve the SystemC semantics under OoO PDES\, a compiler based approach statically analyzes the race conditions in the input model. However\, there are severe restrictions: the source code for the input design must be available in one file\, which does not scale. This disables the use of Intellectual Property (IP) and hierarchical file structures. In this dissertation\, we propose a partial-graph based approach to scale the static analysis to support separate files and IP reuse. Specifically\, the Partial Segment Graph (PSG) data structure is proposed and is used to abstract the behaviours and communication of modules within a single translation unit. These partial graphs are combined at top level to reconstruct the complete behaviors and communication of the entire model. \nWe also propose new algorithms to support the static analysis for modern SystemC TLM-2.0 standard. SystemC TLM-2.0 is widely used in industrial ESL designs for better interoperability and higher simulation speed. However\, it is identified as an obstacle for parallel SystemC simulation due to the disappearance of channels. To solve the problem\, we propose a compile time approach to statically analyze potential conflicts among threads in SystemC TLM-2.0 loosely- and approximately-timed models. A new Socket Call Path (SCP) technique is introduced which provides the compiler with socket binding information for precise static analysis. Based on SCP\, an algorithm is proposed to analyze entangled variable pairs for automatic and accurate conflict analysis. \nBesides the works on the compiler side\, we focus as well on increasing the simulation speed of OoO PDES. We observe that the granularity of the Segment Graph (SG) data structure used in static analysis has a high impact on OoO PDES. This motivates us to propose a set of coding guidelines for the RISC users to properly refine their SystemC model for a higher simulation speed. \nFurthermore\, in this dissertation\, an algorithm is proposed to optimize directly the event delivery strategy in OoO PDES. Event delivery in OoO PDES was very conservative\, which often postponed the execution of waiting threads due to unknown future behaviors of the SystemC model\, and in turn became a bottleneck of simulation speed. The algorithm we propose takes advantage of the prediction of future thread behaviors\, and therefore allows waiting threads to resume execution earlier\, resulting in significantly increased simulation speed. \nTo summarize\, the contributions of this dissertation include: 1) a scalable RISC tool flow for statically analyzing and protecting 3rd party IPs in models with multiple files\, 2) an advanced static analysis approach for modern SystemC TLM-2.0 models\, 3) a set of coding guidelines for RISC users to achieve higher simulation speed\, and 4) a more efficient event delivery algorithm in OoO PDES scheduler using prediction information. \nTogether\, these compiler and simulator advances enable OoO PDES for larger and modern model simulation and thus improve the design of embedded systems significantly\, leading to better devices at lower cost in the end. \n

SUMMARY:Design and Implementation of Robust Full-Duplex Wireless Network
DESCRIPTION:Name: Sergey Shaboyan\nChair: Prof. Ahmed Eltawil \nDate: March 10th\, 2020 \nTime: 09:30 AM \nLocation:  EH 3206 \nCommittee: Prof. Ahmed Eltawil (Chair)\, Prof. Ender Ayanoglu\, Prof. Zhiying Wang \nTitle: “Design and Implementation of Robust Full-Duplex Wireless Network” \nAbstract: \nRecently Full-Duplex (FD) communication has gained significant interest due to demonstrable increase in throughput and spectral efficiency. Conventional Half-duplex (HD) communication systems use either time-duplexing or frequency-duplexing to avoid self-interference. In contrast\, full-duplex systems transmit and receive simultaneously on the same frequency band\, thus optimally utilizing available resources. The main challenge in FD systems is managing the self-interference (SI) signal at each node\, which is typically orders of magnitude larger than the intended signal of interest (SOI). To achieve sufficient SI suppression\, FD systems rely on cancellation across multiple domains such as spatial\, analog\, and digital. However\, number of practical\, FD specific challenges arise impacting quality of service\, when at least one node in a network operates in full-duplex mode. \nIn this thesis\, we consider practical issues of wireless networks containing a full-duplex node. The ultimate goal of this work is to design and implement real-time\, end-to-end networks consisting of at least one FD node that is capable of improving network performance under limited available bandwidth constraint. First\, we identify synchronization issues in a network consisting of a full-duplex base station communicating with half-duplex nodes. Novel synchronization techniques specific for full-duplex networks are proposed that allow compensation of synchronization errors in time and frequency. The proposed techniques are implemented and tested experimentally on a real-time full-duplex wireless network. Second\, we characterize the dynamic environment impact on the received self-interference in the FD system\, which is equipped with a reconfigurable antenna as a passive SI suppression mechanism. The self-interference channel delay profile is measured using the FD system operating on 5MHz\, 10MHz\, and 20MHz bandwidths. The measured channel profiles collected under suppressing and non-suppressing antenna patterns are compared\, and channel changes in static\, as well as dynamic environments\, are highlighted. We then statistically model the SI channel by performing probability distribution fitting to SI channel data. Third\, the thesis proposes a Wi-Fi compliant self-interference active cancellation technique for amplify and forward\, as well as decode and forward full-duplex relays. Finally\, we design and implement an end-to-end wireless network extended with the aid of a custom-designed amplify and forward full-duplex relay. We then analyze the relay coverage limitation under the stability and transmit power constraints. The network performance is analyzed as a function of relay location for constant gain and constant transmit power modes\, consequently suggesting optimal relay location that will maximize signal to noise plus interference ratio (SINR) at the destination node. We evaluate the overall network performance by simulation\, as well as experimentally in outdoor/indoor environments.

SUMMARY:"Answering Multi-Dimensional Analytical Queries under Local Differential Privacy"
DESCRIPTION:Name: Tianhao Wang\nDate and Time: Thursday\, February 27\, 2020 \nLocation: Engineering Hall 2430 \nAbstract: \nWhen collecting information\, local differential privacy (LDP) relieves users’ privacy concerns\, as it adds noise to users’ private information.  The LDP technique has been deployed by Google\, Apple\, and Microsoft for data collection and monitoring.  In this talk\, I will share the key algorithms we developed in a Chinese e-commercial company Alibaba.  We study the problem of answering multi-dimensional queries under LDP.  Several algorithms are proposed to handle queries with different types of predicates and aggregation functions.  We built a prototype that enables different departments to collect\, share\, and analyze data within the company. \nBiography: \nTianhao Wang is a Ph.D. candidate in the department of computer science\, Purdue University\, advised by Prof. Ninghui Li. He received his B.Eng. degree from software school\, Fudan University in 2015. His research interests include differential privacy and local differential privacy. He is a recipient of the Bilsland Dissertation Fellowship and the Emil Stefanov Memorial Fellowship. He was a member of DPSyn\, which won the second-place award in the NIST PSCR Differential Privacy Synthetic Data Challenge.

SUMMARY:Novel Monitoring\, Detection\, and Optimization Techniques for Neurological Disorders
DESCRIPTION:Name: Seyede Mahya Safavi\nChair: Prof. Pai Chou \nDate: February 20th\, 2020 \nTime: 10:00 AM \nLocation:  EH 3404 \nCommittee: Prof. Pai Chou (Chair)\, Prof. Beth Lopour\, Prof. Phillip Sheu \nTitle: “Novel Monitoring\, Detection\, and Optimization Techniques for Neurological Disorders” \nAbstract: \nThe advancement in chronically implanted neural recording devices has led to advent of assisting devices for rehabilitation and restoring lost sensorimotor functions in patients suffering from paralysis. Electrocorticogram (ECoG) signal can record high-Gamma sub-band activity known to be related to hand movements. In the first part of this work\, we Propose a finger movement detection technique based on ECoG source localization. In fact\, the finger flexion and extension are originating in slightly different areas of motor cortex. The origin of the brain activity is used as the distinctive feature for decoding the finger movement. \nThe real-time implementation of brain source localization is challenging due to extensive iterations in the existing solutions. In the second part of this work\, we have proposed two techniques to reduce the computational complexity of the Multiple Signal Classification (MUSIC) algorithm. First the cortex surface is parsed into several regions. Next\, a novel nominating procedure will pick a number of regions to be searched for brain activity. In the second step\, an electrode selection technique based on the Cramer-Rao bound of the errors is proposed to select the best set of an arbitrary number of electrodes. The proposed techniques lead to 90% reduction in computational complexity while maintaining a good concordance in terms of localization error compared to regular MUSIC algorithm. \nEpilepsy is a neurological disorder with multiple comorbid conditions including cardiovascular and respiratory disorders. The cardiovascular imbalance is of great importance since the mechanisms of Sudden Unexpected Death in Epilepsy (SUDEP) is still unknown. The ictal tachycardia is the most well-known cardiac imbalance during the seizure. In the third part of this dissertation\, we used an optical sensor called photoplethysmogram (PPG) to investigate the variations in ictal blood flow in limbs. Six different features related to hemodynamics were derived from PPG pulse morphology. A consistent pattern of ictal change was observed across all the subjects/seizures. These variations suggest an increase in vascular resistance due to an increase in sympathetic tone. The timing analysis of the PPG features revealed some PPG feature variations can precede the ictal tachycardia by 50 seconds. These features were used to train a neural network based on Long Short Term Memory LSTM architecture for automatic seizure detection. We were able to reduce the False Alarm rate by 50% compared to other heart rate variability based detectors.

SUMMARY:Efficient Offline and Online Training of Memristive Neuromorphic Hardware
DESCRIPTION:Name: Mohammed Fouda\nChair: Prof. Ahmed Eltawil \nDate: February 6th\, 2020 \nTime: 9:30 AM \nLocation:  EH 3206 \nCommittee: Ahmed Eltawil (Chair)\, Prof. Fadi Kurdahi\, Prof. Nikil Dutt\, Prof. Emre Neftci \nTitle: “Efficient Offline and Online Training of Memristive Neuromorphic Hardware” \nAbstract: \nBrain-inspired neuromorphic systems have witnessed rapid development over the last decade from both algorithmic and hardware perspectives. Neuromorphic hardware promises to be more energy- and speed- efficient as compared to traditional Von-Neumann architectures. Thanks to the recent progress in solid-state devices\, different nanoscale-nonvolatile memory devices\, such as RRAMs (memristors)\, STT-RAM and PCM\, support computations based on mimicking biological synaptic response. The most important advantage of these devices is their ability to be sandwiched between interconnect wires creating crossbar array structures that are inherently able to perform matrix-vector multiplication (MVM) in one step. Despite the great potential of RRAMs\, they suffer from numerous nonidealities limiting the performance\, including\, high variability\, asymmetric and nonlinear weight update\, endurance\, retention and stuck at fault (SAF) defects in addition to the interconnect wire resistance that creates sneak paths. This thesis will focus on the application of RRAMs for neuromorphic computation while accounting for the impact of device nonidealities on neuromorphic hardware. \n\n\n\n\nIn this thesis\, we propose software-level solutions to mitigate the impact of nonidealities\, that highly affect the offline (ex-situ) training\, without incorporating expensive SPICE or numerical simulations. We propose two techniques to incorporate the effect of sneak path problem during training\, in addition to the device’s variability\, with negligible overhead. The first technique is inspired by the impact of the sneak path problem on the stored weights (devices’ conductances) which we referred to as the mask technique. This mask is element-wise multiplied by the weights during the training. This mask can be obtained from measured weights of fabricated hardware. The other solution is a neural network estimator which is trained by our SPICE-like simulator. The test validation results\, done through our SPICE-like framework\, show significant improvement in performance\, close to the baseline BNNs and QNNs\, which demonstrates the efficiency of the proposed methods. Both techniques show the high ability to capture the problem for multilayer perceptron networks for MNIST dataset with negligible runtime overhead. In addition\, the proposed neural estimator outperforms the mask technique for challenging datasets such as CIFAR10. Furthermore\, other nonidealities such as SAF defects and retention are evaluated. \nWe also develop a model to incorporate the stochastic asymmetric nonlinear weight update in online (in-situ) training. We propose two solutions for this problem; 1) a compensation technique which is tested on a small scale problem to separate two Laplacian mixed sources using online independent component analysis. 2) stochastic rounding and is tested on a spiking neural network with deep local learning dynamics showing only a 1~2% drop in the baseline accuracy for three different RRAM devices. We also propose Error-triggered learning to overcome the limited endurance problem with only 0.3% and 3% drop in the accuracy for N-MNIST and DVSGesture datasets with around 33X and 100X reduction in the number of writes\, respectively. \nFinally\, the prospects of this neuromorphic hardware are discussed to develop new algorithms with the existing resistive crossbar hardware including its nonidealities.
