Redesigning the Nantucket Town Website
To enhance the use of e-governance on Nantucket, the Town of Nantucket decided to redesign its town website. The Nantucket IT Department desired a website that allowed users to easily find information and was also easy for town officials to keep up to date. In order to help address both residents’ and town employees’ needs, the team conducted surveys and a series of department meetings, and also analyzed data from the previous Nantucket Town Website. The project resulted in a list of recommendations on the design, content, and functionalities of the new Nantucket Town Website
Modular Robotic Arm
The following paper describes the process and results undertaken to create a modular robotic arm system. The intent of the project was to create a low cost modular robotic arms system with features seen in more expensive systems as such a product does not exist on the market today. By following a systems engineering approach, our team was able to develop a modular robotic joint in an attempt to fill this market gap
Preference-grounded Token-level Guidance for Language Model Fine-tuning
Aligning language models (LMs) with preferences is an important problem in
natural language generation. A key challenge is that preferences are typically
provided at the sequence level while LM training and generation both occur at
the token level. There is, therefore, a granularity mismatch between the
preference and the LM training losses, which may complicate the learning
problem. In this paper, we address this issue by developing an alternate
training process, where we iterate between grounding the sequence-level
preference into token-level training guidance, and improving the LM with the
learned guidance. For guidance learning, we design a framework that extends the
pairwise-preference learning in imitation learning to both variable-length LM
generation and utilizing the preference among multiple generations. For LM
training, based on the amount of supervised data, we present two minimalist
learning objectives that utilize the learned guidance. In experiments, our
method performs competitively on two distinct representative LM tasks --
discrete-prompt generation and text summarization
An analytical modeling for high-velocity impacts on woven Kevlar composite laminates
In this paper, an analytical model, which based on energy balance, is built to study the process of high velocity impacts on woven Kevlar composite laminates by a cylindrical projectile. Four different mechanisms, such as laminate crushing, linear momentum transfer and tensile fiber failure, and shear plugging, is absorbed by the laminate while impacting. Then, simplification of the model is done to obtain the residual velocity and ballistic limit. The analytical results are validated with the results of experiment, and the perturbation analysis is done to analyze the reason of error
A Comparative Study of Image Restoration Networks for General Backbone Network Design
Despite the significant progress made by deep models in various image
restoration tasks, existing image restoration networks still face challenges in
terms of task generality. An intuitive manifestation is that networks which
excel in certain tasks often fail to deliver satisfactory results in others. To
illustrate this point, we select five representative image restoration networks
and conduct a comparative study on five classic image restoration tasks. First,
we provide a detailed explanation of the characteristics of different image
restoration tasks and backbone networks. Following this, we present the
benchmark results and analyze the reasons behind the performance disparity of
different models across various tasks. Drawing from this comparative study, we
propose that a general image restoration backbone network needs to meet the
functional requirements of diverse tasks. Based on this principle, we design a
new general image restoration backbone network, X-Restormer. Extensive
experiments demonstrate that X-Restormer possesses good task generality and
achieves state-of-the-art performance across a variety of tasks
FIRST: A Million-Entry Dataset for Text-Driven Fashion Synthesis and Design
Text-driven fashion synthesis and design is an extremely valuable part of
artificial intelligence generative content(AIGC), which has the potential to
propel a tremendous revolution in the traditional fashion industry. To advance
the research on text-driven fashion synthesis and design, we introduce a new
dataset comprising a million high-resolution fashion images with rich
structured textual(FIRST) descriptions. In the FIRST, there is a wide range of
attire categories and each image-paired textual description is organized at
multiple hierarchical levels. Experiments on prevalent generative models
trained over FISRT show the necessity of FIRST. We invite the community to
further develop more intelligent fashion synthesis and design systems that make
fashion design more creative and imaginative based on our dataset. The dataset
will be released soon.Comment: 11 pages, 8 figure
