Title: A Potpourri of Ideas and Results in DRAM, FPGA Infrastructures, and RISC-V Processors

Abstract: In this talk, I will give an overview of some recent ideas and results in DRAM based random number generation, FPGA based DRAM testing and evaluation infrastructures, undervolting in FPGAs, and RISC-V processor design. This presentation will cover innovative advancements in True Random Number Generators (TRNGs) and FPGA efficiency. Specifically, the talk describes QUAC-TRNG, a high-throughput TRNG that can be implemented in commodity DRAM chips, demonstrating substantial improvements in throughput and utilization compared to state-of-the-art DRAM-based TRNGs. It also introduces DR-STRaNGe, an end-to-end system design addressing the key challenges associated with DRAM-based TRNGs, achieving significant improvements in performance, fairness, and energy consumption. The talk will outline a new experimental infrastructure, DRAM Bender, and briefly discuss the Processing-in-DRAM framework (PiDRAM) to facilitate in-memory processing. The presentation will further explore the effects of undervolting FPGAs on the efficiency and accuracy of convolutional neural network benchmarks, including the surprising impact of temperature and humidity on fault rates. Finally, the ongoing work on utilizing the occurring faults in FPGA undervolting for random number generation (TuRaN) will be discussed, reflecting a broad exploration of cutting-edge techniques in TRNGs, DRAM technology, and FPGA efficiency.
Before we conclude our presentation, we will explain the RISC-V based processor core design efforts in our KASIRGA research group.

Title: Semantic Signal Processing and Communications

Abstract: Recent advances in machine learning enabled real time extraction of semantic information at the sensor node enabling goal oriented semantic signal processing and communications. For efficient goal-oriented signal processing on the extracted semantic information, a hierarchical graph-based semantic language is proposed.  In this way, semantic filtering of the extracted information can be achieved at the sensor node with a dramatic reduction in the rate of communication in the network.  The proposed semantic signal processing and communications framework can easily be tailored for specific applications and goals in a diverse range of applications. As illustrated over simulated and real sensor data, the proposed framework enables several orders of magnitude reduction in the rate of communication.

Title: Demystifying the learning dynamics in high dimensional setting

Abstract: The remarkable success of deep learning algorithms has revolutionized the field of machine learning. However, theoretical understanding of their learning dynamics is still limited. Statistical physics and random matrix theory emerge as two powerful tools to unravel the mystery of the empirical success of these models. Statistical physics aims to map large dimensional learning problems into physics-inspired problems of interacting with many particles. Such methods have been tremendously successful in understanding the macroscopic properties of many-body interactive systems. As such, the generalization ability of neural networks can be analyzed for a range of typical-case scenarios unlike the worst-case type bounds which are provided by traditional learning theory approaches. Therefore, they are gradually recognized as indispensable tools in the study of large-dimensional learning problems. Yet, new analysis frameworks are required to capture the full dynamics of deep networks. Alternatively, many new random matrix ensembles arise in learning problems. As growing interest indicates, the spectral properties of these matrices may help answer crucial questions regarding the training and generalization performance of deep networks, and the fundamental limits of high-dimensional learning. Unlike their classical counterparts, these new random matrices are often highly structured and are the result of nonlinear transformations. This combination of structure and nonlinearity leads to substantial technical challenges when applying existing tools from random matrix theory to these new ensembles. In this talk, I will provide an overview of the two approaches with the ultimate goal of achieving a complete understanding of the theory of deep learning. Specifically, I will provide some recent examples of an exact characterization of the asymptotic training and generalization errors of high-dimensional learning by exploiting a general universality concept in high dimensional setting.

Bio: Zafer Doğan is currently working as an assistant professor of electrical and electronics engineering at Koç University, where he leads the Machine Learning Information Processing (MLIP) Research Group under the KUIS Artificial Intelligence Research Center. His research is focused on the dynamics of learning algorithms for large-scale non-convex optimization problems, the interpretability and explainability of artificial learning models, and the theoretical understanding of well-behaved non-convex optimization and deep learning frameworks. He also explores specific applications in artificial learning frameworks to provide stability, tractability, and reproducibility features. This comprehensive understanding of these models will be key to achieving continuous advancement in the field and to the widespread acceptance of data-driven systems in the future.

Before his current position, he was a postdoctoral research fellow at the John A. Paulson School of Engineering and Applied Sciences at Harvard University from 2016 to 2019, and at the Campus Biotech of Ecole Polytechnique Federale de Lausanne (EPFL) in Geneva from 2015 to 2016. He received his Ph.D. and M.Sc degrees in electrical engineering from EPFL, Switzerland, in 2015 and 2011, respectively. His Ph.D. work focused on sparse signal representation in data processing, including sparse signal representations, sampling and approximation, multiresolution analysis, and the theory of finite rate of innovation, as well as inverse problems in nonlinear tomography and neuroimaging. He obtained his B.Sc. degree in Electrical and Electronics Engineering from Middle East Technical University (METU) in 2009.
