To navigate the in-tractable search space of mixed-precision configurations for a given network, this paper proposes a hybrid search methodology. It consists of a hardware-agnostic differentiable search algorithm followed by a hardware-aware heuristic optimization to find mixed-precision configurations latency-optimized for a specific hardware target. We evaluate our algorithm on MobileNetV1 and MobileNetV2 and deploy the resulting networks on a family of multi-core RISC-V microcontroller platforms with different hardware characteristics. We achieve up to 28.6 % reduction of end-to-end latency compared to an 8-bit model at a negligible accuracy drop from a full-precision baseline on the 1000-class ImageNet dataset. We demonstrate speedups relative to an 8-bit baseline, even on systems with no hardware support for sub-byte arithmetic at negligible accuracy drop. Furthermore, we show the superiority of our approach with respect to differentiable search targeting reduced binary operation counts as a proxy for latency.","PeriodicalId":296649,"journal":{"name":"2023 IEEE 5th International Conference on Artificial Intelligence Circuits and Systems (AICAS)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130372354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Weight encryption is an effective method, but existing ciphertext computing accelerators cannot achieve high encryption complexity and flexibility. This paper proposes WeightLock, a mixed-grained hardware-software co-design approach based on local decrypting units (LDUs). This work proposes a key-controlled cell-level hardware design for higher granularity and two weight selection schemes for higher flexibility. The simulation results show that the accuracy of VGG-8 and ResNet-18 in the Cifar-10 classification drops from 80% to only 10% even if 80% of keys are leaked. This shows >20% higher key leakage tolerance and >17x longer retraining latency protection, compared with the prior state-of-the-art hardware and software approaches, respectively.

The General Matrix Multiplication is the fundamental and the most important computing kernel routine extensively utilized in the ML workloads. Generally, the whole GEMM workload is partitioned into a series of blocks and the sub-tasks are professionally assembled to exploit the parallel hardware. However, it is not the case for the cloud workloads which process multi-tasks concurrently and expect guaranteed QoS for commercial consideration. We introduce the task-aware parallel scheduling method to process the ML workloads and balance the response delay and the throughput of the YiTian710 ECS instance. We furtherly design a multi-thread scheduling algorithm with two-level division for the GEMM sub-tasks to achieve high efficiency. The optimized GEMM kernels are developed to attain the optimal performance. We evaluate the performance in YiTian710 based Alicloud ECS for different applications.

Sophisticated learning-based image processing becomes a promising solution to close this gap. In this paper, we propose an Image Frequency Separation Residual Network (IFS Net) to perform the end-to-end RAW to RGB image mapping. Different from existing methods that directly train the input image and the ground truth image one-to-one as a whole, our proposed method first divides the input image and the ground truth into high-frequency and low-frequency parts by discrete wavelet transform (DWT). These two parts are then trained separately using different networks for details and global information, and finally synthesized into the output image using inverse DWT. Experimental results show that the proposed IFS Net outperforms other existing algorithms in both PSNR and SSIM. Visual comparison shows that the images produces by IFS Net preserves more details and look close to that captured by DSLR cameras.","PeriodicalId":296649,"journal":{"name":"2023 IEEE 5th International Conference on Artificial Intelligence Circuits and Systems (AICAS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130957977","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Besides fine appearance details of the face from RGB images, we use depth images that present the 3D contour of the face to improve recognition performance in large poses. At first, we propose a dual-path RGB-D face recognition model which learns features from separate RGB and depth images and fuses the two features into one identity feature. We add associate loss to strengthen the complementary and improve performance. Second, we proposed a landmark-based adversarial network to help the face recognition model extract the pose-invariant identity feature. Our landmark-based adversarial network contains a feature generator, pose discriminator, and landmark module. After we use 2-stage optimization to optimize the pose discriminator and feature generator, we removed the pose factor in the feature extracted by the generator. We conduct experiments on KinectFaceDB, RealSensetest and LiDARtest. On KinectFaceDB, we achieve a recognition accuracy of 99.41%, which is 1.31% higher than other methods. On RealSensetest, we achieve a classification accuracy of 92.57%, which is 30.51% higher than other methods.
