Offering incentives (e.g., coupons at Amazon, discounts at Uber and video bonuses at Tiktok) to user is a common strategy used by online platforms to increase user engagement and platform revenue. Despite its proven effectiveness, these marketing incentives incur an inevitable cost and might result in a low ROI (Return on Investment) if not used properly. On the other hand, different users respond differently to these incentives, for instance, some users never buy certain products without coupons, while others do anyway. Thus, how to select the right amount of incentives (i.e. treatment) to each user under budget constraints is an important research problem with great practical implications. In this paper, we call such problem as a budget-constrained treatment selection (BTS) problem. The challenge is how to efficiently solve BTS problem on a Large-Scale dataset and achieve improved results over the existing techniques. We propose a novel tree-based treatment selection technique under budget constraints, called Large-Scale BudgetConstrained Causal Forest (LBCF) algorithm, which is also an efficient treatment selection algorithm suitable for modern distributed computingsystems. A novel offline evaluation method is also proposed to overcome an intrinsic challenge in assessing solutions' performance for BTS problem in randomized control trials (RCT) data. We deploy our approach in a real-world scenario on a largescale video platform, where the platform gives away bonuses in order to increase users' campaign engagement duration. The simulation analysis, offline and online experiments all show that our method outperforms various tree-based state-of-the-art baselines 1. The proposed approach is currently serving over hundreds of millions of users on the platform and achieves one of the most tremendous improvements over these months.

3D printing is bringing revolutionary changes to the field of medicine, with applications ranging from hearing aids to regrowing organs. As our society increasingly relies on this technology to save lives, the security of these systems is a growing concern. However, existing defense approaches that leverage side channels may require domain knowledge from computer security to fully understand the impact of the attack. To bridge the gap, we propose XCheck, which leverages medical imaging to verify the integrity of the printed patient-specific device (PSD). XCheck follows a defense-in-depth approach and directly compares the computed tomography (CT) scan of the printed device to its original design. XCheck utilizes a voxel-based approach to build multiple layers of defense involving both 3D geometric verification and multivariate material analysis. To further enhance usability, XCheck also provides an adjustable visualization scheme that allows practitioners' inspection of the printed object with varying tolerance thresholds to meet the needs of different applications. We evaluated the system with 47 PSDs representing different medical applications to validate the efficacy.

The end of Moore's Law and Dennard scaling has driven the proliferation of heterogeneous systems with accelerators, including CPUs, GPUs, and FPGAs, each with distinct architectures, compilers, and programming environments. GPUs excel at massively parallel processing for tasks like deep learning training and graphics rendering, while FPGAs offer hardware-level flexibility and energy efficiency for low-latency, high-throughput applications. In contrast, CPUs, while general-purpose, often fall short in high-parallelism or power-constrained applications. This architectural diversity makes it challenging to compare these accelerators effectively, leading to uncertainty in selecting optimal hardware and software tools for specific applications. To address this challenge, we introduce HeteroBench, a versatile benchmark suite for heterogeneous systems. HeteroBench allows users to evaluate multi-compute kernel applications across various accelerators, including CPUs, GPUs (fromNVIDIA, AMD, Intel), and FPGAs (AMD), supporting programming environments of Python, Numba-accelerated Python, serial C++, OpenMP (both CPUs and GPUs), OpenACC and CUDA for GPUs, and Vitis HLS for FPGAs. This setup enables users to assign kernels to suitable hardware platforms, ensuring comprehensive device comparisons. What makes HeteroBench unique is its vendor-agnostic, cross-platform approach, spanning diverse domains such as image processing, machine learning, numerical computation, and physical simulation, ensuring deeper insights for HPC optimization. Extensive testing across multiple systems provides practical reference points for HPC practitioners, simplifying hardware selection and performance tuning for both developers and end-users alike. This suite may assist to make more informed decision on AI/ML deployment and HPC development, making it an invaluable resource for advancing academic research and industrial applications.
