A Complementary Measure of MIS Program Outcomes: Useful Insights from a Student Perspective
Assessing student learning is a critical element in today’s higher education environment. Learning assurance programs seek to assess and improve the quality of student learning, and may employ both direct and indirect measures. In this paper, we describe a practical learning assurance assessment measure developed and used as a part of a broader program to evaluate and monitor the learning of students in our Management Information Systems major. This measure enables us to evaluate our students’ learning as reflected by their confidence, persistence, and willingness to undertake MIS-related tasks. We believe this is an important indicator of learning. This paper describes our development of this measure, use of the measure as an element of our learning assurance program for our MIS major, and insights gained from this assessment approach
From Short-term Hotspot Measurements to Long-term Module Reliability
AbstractIn order to reach high module reliability, all solar cells with a potentially critical hotspot have to be neglected during cell sorting. This is essential to avoid delamination in case of partial shading of the module. Due to throughput considerations, the finished solar cell has to be classified within some milliseconds. In consequence the short-term hotspot heating measurement has to be correlated to absolute hotspot temperatures for various module conditions in the field. Previously it has already been shown that a definite mapping of these quantities is not possible, requiring further investigations in order to quantify the risk for possible module damage.In this contribution, the probability distribution for absolute hotspot temperatures in the module will be calculated from short-term hotspot measurement data, considering temperature-dependent reverse biases. Together with experimental data for module delamination temperatures, the probability of module failure can be calculated in a direct way
Momentum-based Weight Interpolation of Strong Zero-Shot Models for Continual Learning
Large pre-trained, zero-shot capable models have shown considerable success
both for standard transfer and adaptation tasks, with particular robustness
towards distribution shifts. In addition, subsequent fine-tuning can
considerably improve performance on a selected downstream task. However,
through naive fine-tuning, these zero-shot models lose their generalizability
and robustness towards distribution shifts. This is a particular problem for
tasks such as Continual Learning (CL), where continuous adaptation has to be
performed as new task distributions are introduced sequentially. In this work,
we showcase that where fine-tuning falls short to adapt such zero-shot capable
models, simple momentum-based weight interpolation can provide consistent
improvements for CL tasks in both memory-free and memory-based settings. In
particular, we find improvements of over on standard CL benchmarks,
while reducing the error to the upper limit of jointly training on all tasks at
once in parts by more than half, allowing the continual learner to inch closer
to the joint training limits.Comment: First Workshop on Interpolation Regularizers and Beyond, NeurIPS 2022

Teaching Programming Via The Web: A Time-Tested Methodology
Advances in information and communication technologies give us the ability to reach out beyond the time and place limitations of the traditional classroom. However, effective online teaching is more than just transferring traditional courses to the World Wide Web (WWW). We describe how we have used “off the shelf” software and the infrastructure that is available via the WWW to develop and deliver a complete learning experience in programming business applications using a popular programming language. The course is unique in its coordinated use of traditional and nontraditional materials to introduce and explain difficult programming constructs. Student performance, job placement, and feedback have confirmed the convenience and effectiveness of this method
Vision-by-Language for Training-Free Compositional Image Retrieval
Given an image and a target modification (e.g an image of the Eiffel tower
and the text "without people and at night-time"), Compositional Image Retrieval
(CIR) aims to retrieve the relevant target image in a database. While
supervised approaches rely on annotating triplets that is costly (i.e. query
image, textual modification, and target image), recent research sidesteps this
need by using large-scale vision-language models (VLMs), performing Zero-Shot
CIR (ZS-CIR). However, state-of-the-art approaches in ZS-CIR still require
training task-specific, customized models over large amounts of image-text
pairs. In this work, we propose to tackle CIR in a training-free manner via our
Compositional Image Retrieval through Vision-by-Language (CIReVL), a simple,
yet human-understandable and scalable pipeline that effectively recombines
large-scale VLMs with large language models (LLMs). By captioning the reference
image using a pre-trained generative VLM and asking a LLM to recompose the
caption based on the textual target modification for subsequent retrieval via
e.g. CLIP, we achieve modular language reasoning. In four ZS-CIR benchmarks, we
find competitive, in-part state-of-the-art performance - improving over
supervised methods. Moreover, the modularity of CIReVL offers simple
scalability without re-training, allowing us to both investigate scaling laws
and bottlenecks for ZS-CIR while easily scaling up to in parts more than double
of previously reported results. Finally, we show that CIReVL makes CIR
human-understandable by composing image and text in a modular fashion in the
language domain, thereby making it intervenable, allowing to post-hoc re-align
failure cases. Code will be released upon acceptance
