We introduce the Yi model family, a series of language and multimodal models that demonstrate strong multi-dimensional capabilities. The family is based on 6B 34B pretrained models, then we extend them to chat 200K long context depth-upscaled vision-language models. Our base achieve performance wide range benchmarks like MMLU, our finetuned deliver human preference rate major evaluation platforms AlpacaEval Chatbot Arena. Building upon scalable super-computing infrastructure classical...
Despite the continuing efforts to improve engagingness and consistency of chit-chat dialogue systems, majority current work simply focus on mimicking human-like responses, leaving understudied aspects modeling understanding between interlocutors. The research in cognitive science, instead, suggests that is an essential signal for a high-quality conversation. Motivated by this, we propose Pˆ2 Bot, transmitter-receiver based framework with aim explicitly understanding. Specifically, Bot...
Combining data content with visual embellishments, infographics can effectively deliver messages in an engaging and memorable manner. Various authoring tools have been proposed to facilitate the creation of infographics. However, creating a professional infographic these is still not easy task, requiring much time design expertise. Therefore, are generally attractive casual users, who either unwilling take learn or lacking proper expertise create infographic. In this paper, we explore...
Recent progress in language model pre-training has achieved a great success via leveraging large-scale unstructured textual data. However, it is still challenge to apply on structured tabular data due the absence of high-quality In this paper, we propose TAPEX show that table can be by learning neural SQL executor over synthetic corpus, which obtained automatically synthesizing executable queries and their execution outputs. addresses scarcity guiding mimic diverse, corpus. We evaluate four...
Adsorption techniques have been successfully applied in water purification because of their flexibility, simplicity design, and effectiveness. Activated carbon is an effective absorbent using for dye adsorption; however, the powder structure not conducive practical applications cannot be used to filter solutions which are challenges that still need addressed. Herein, a natural cellulose-based absorbent, activated carbon-Juncus effusus fiber (AC-JE fiber), demonstrates removal all kinds dyes...
Few-shot learning is a challenging task that requires language models to generalize from limited examples. Large like GPT-3 and PaLM have made impressive progress in this area, but they still face difficulties reasoning tasks such as GSM8K, benchmark for arithmetic problems. To improve their skills, previous work has proposed guide the model with prompts elicit series of steps before giving final answer, achieving significant improvement on GSM8K 17.9% 58.1% problem-solving rate. In paper,...

Photodetectors (PDs) with broadband photoresponse can meet the demand for multiband detection in complex environments, overcoming technological complexity issue of integrated narrow-band PDs. Self-powered heterojunction PDs having ultraviolet–visible–near-infrared were constructed by using SnO2 nanopillars and CuInS2 nanoflakes. The dimension, crystalline quality, energy level structure regulated changing concentration Sn ions precursor solution. optimized interfacial band increase transfer...
Recent years the task of incomplete utterance rewriting has raised a large attention. Previous works usually shape it as machine translation and employ sequence to based architecture with copy mechanism. In this paper, we present novel extensive approach, which formulates semantic segmentation task. Instead generating from scratch, such formulation introduces edit operations shapes problem prediction word-level matrix. Benefiting being able capture both local global information, our approach...
Ultra-wideband (UWB) technology differentiates itself from other wireless connectivity techniques, such as WiFi and Bluetooth, by providing centimeter-level location accuracy due to its impulse-radio operation. This unique feature draws much interest in smartphones, smart homes, intelligent vehicles, AR/VR, loT applications since accurate ranging/positioning adds a new dimension existing communication functions. The recently released IEEE 802.15.4z enhances UWB PHYs increase the integrity of...
Automated debugging techniques have the potential to reduce developer effort in debugging, and matured enough be adopted by industry. However, one critical issue with existing is that, while developers want rationales for provided automatic results, are ill-suited provide them, as their deduction process differs significantly from that of human developers. Inspired way interact code when we propose Scientific Debugging (AutoSD), a technique given buggy bug-revealing test, prompts large...
The study investigated the chlorine and fluorine contents in three types of industrial solid waste: textile, plastic, paper waste, utilizing various analytical methods. Significant variations proportions organic inorganic were observed among waste types. During heat treatment, majority converts to a volatile state, with fixed content showing correlation chlorine. Organic predominated all types, predominantly transitioning state during treatment. Notably, textile exhibited unique behaviour,...
Tailoring water supply to achieve confined heating has proven be an effective strategy for boosting solar interfacial evaporation rates. However, because of salt clogging during desalination, a critical point constriction occurs when controlling the rate heating. In this study, we demonstrate facile and scalable weaving technique fabricating core–sheath photothermal yarns that facilitate controlled stable efficient desalination. The yarn comprises modal fibers as core carbon sheaths. Because...
