Jeremy Bos (ECE) was quoted and PhD student Zach Jeffries (electrical engineering) and Akhil Kurup ’22 (PhD, computer engineering) were mentioned by SPIEGreen Car CongressTech XploreBioengineering.org and SCIENMAG in a story about a three-year effort to develop tests and performance standards for lidars used in autonomous vehicles and advanced driver assistance systems.

Bos led the testing through its first year, with Jeffries’ assistance. The team’s findings are detailed in an open-access paper published this month in Optical Engineering.

Extract

This paper describes the initial results from the first of 3 years of planned testing aimed at developing methods, metrics, and targets necessary to develop standardized tests for these instruments. Here, we evaluate range error accuracy and precision for eight automotive grade lidars; a survey grade lidar is used as a reference. These lidars are tasked with detecting a static, child-sized, target at ranges between 5 and 200 m.

Our purpose in this work is to motivate the development of test standards in this area and highlight variations in performance between lidars when stated specifications are similar.

Proposed additions to the testing include more complex targets, dynamic targets, placing corner cubes, or identical lidars on the test range, and weather effects.

Lucas and Whitaker Place in Computing[MTU] Showcase Poster Session

The Institute of Computing and Cybersystems has announced the winners of the first Computing[MTU] Showcase Poster Session. Among the winners were electrical and computer engineering graduate students Evan Lucas and Steven Whitaker for “Active learning with binary feedback on multiclass problems,” who were tied for second place with Suresh Pokharel of Computer Science.

Active learning with binary feedback on multiclass problems

An active learning approach is often used for multiclass classification problems, where predictions are made on new data and a human user is used to determine if the predictions are correct. Typical approaches may ask a human to select the correct class if the prediction is incorrect. This work attempts to use a binary feedback on the predicted classes to save time and allow maximal use of a negative prediction on a partly trained model.

Soft Community Detection

Sakineh “Audrey” Yazdanparast (ECE), Timothy C. Havens (CC), and Mohsen Jamalabdollahi have authored “Soft Overlapping Community Detection in Large-Scale Networks via Fast Fuzzy Modularity Maximization,” which is available under the “Early Access” area on IEEE Xplore.

Extract

Soft overlapping clustering is one of the notable problems of community detection. Extensive research has been conducted to develop efficient methods for non-overlapping and crisp-overlapping community detection in large-scale networks. In this paper, Fast Fuzzy Modularity Maximization (FFMM) for soft overlapping community detection is proposed. FFMM exploits novel iterative equations to calculate the modularity gain associated with changing the fuzzy membership values of network vertices. The simplicity of the proposed scheme enables efficient modifications, reducing computational complexity to a linear function of the network size and the number of communities.

Kunle Olutomilayo Leads Outreach on True African Story

Kunle Olutomilayo
Kunle Olutomilayo

On May 15, 2019, eight students from the African Students Organization (ASO) chapter of Michigan Tech went to Dollar Bay High School to share a perspective of African history and culture that is often misrepresented or ignored by Western media.

Meeting a class of middle and high school students, Kunle Olutomilayo (PhD student, ECE), president of ASO, opened the floor with introductory remarks. Highlighting the historical significance of Africa to human existence. ASO’s interaction with the Dollar Bay School involved an exposition of West African naming practices, a telling of Asante folklore, a video showing different places in all 54 African countries, and a lesson on some facts about the African continent that are rarely pointed out.

Tolu Odebunmi (PhD student, Humanities) explained how the pronunciation of names worked in Yoruba, one of several languages in Nigeria. By referring to the tonal nature of Yoruba pronunciation, Tolu explained how names were significant in most African cultures. Of particular interest was the meanings attached to names and how the circumstances surrounding the birth of a child could dictate the name that was given to a child. For example, some ethnic groups in Ghana name their children based on the day of the week that a child is born.

While the video served as a means to retell the African story, the lesson led by Alfred Owusu-Ansah (PhD student, Humanities) highlighted rarely mentioned issues; Alfred pointed out how the world’s oldest university was established in 859 C.E. in Morocco by a woman. He also pointed out other firsts, like the first successful heart transplant was achieved in South Africa. In encouraging the students to explore the rich diversity of Africa, he suggested that they could read Nobel Laureates like Wole Soyinka of Nigeria or Nadine Gordimer of South Africa; or follow great scientists like Sameera Moussa (a renowned nuclear scientist) of Egypt, and Philip Emeagwali of Nigeria, who built the fastest computer of the time in 1989.

After the lesson students were invited to ask questions. This led to what was perhaps the climax of the day when a very bright student asked: “We hear that Africans are corrupt, how true is that?” Alfred pointed out that corruption does exist at different levels in the different countries in Africa; the same way that corruption exists at different levels in all countries in the world. Alfred highlighted the importance of checks and balances in any system of governance that seeks to minimize corrupt practices, which is as true for Africa as it is for North America. This led to a conversation on the cultural differences between African countries and the United States of America. It was clear that both Africans and Americans had a lot of respect for each other and were eager to learn new things. Ending the interaction with a song, the president of ASO sees this interaction as one of many that can help both Africans and the people of the great Upper Peninsula understand each other better.

(L-R) Award recipients Aref Majdara and Navid Gandji

The Department of Electrical and Computer Engineering announced its award recipients for 2016-2017 at the Annual ECE Graduate Student Banquet held on September 25. Aref Majdara received the Jonathan Bara Award for Outstanding Graduate Teaching Assistant and Navid Gandji received the Matt Wolfe Award for Outstanding Graduate Research Assistant.

Dr. Glen Archer, ECE associate chair and TA supervisor said in his nomination “Aref is one of those rare students who seems to excel at everything you ask him to do. He has worked as a TA for several years in a variety of different courses and received praise from the students in every case.” Archer stated that Aref’s performance in the Circuits lab “revealed a quiet patience that motivates students to perform at their best” and in the more difficult to staff labs such as Microcontroller, Embedded System Engineering, and Signal Processing, “Aref accepted these challenges in the same way he faces everything, with purposeful resolve and a relentless pursuit of excellence”. Mr. Majdara’s PhD advisor is Prof. Saeid Nooshabadi.

Dr. Elena Semouchkina, ECE associate professor and PhD advisor stated in her nomination for outstanding GRA, “Navid Gandji’s research features two important aspects: (1) novelty at the frontiers of engineering physics and (2) addressing vital societal needs. Navid’s work is in a very competitive field of artificial materials, including photonic crystals and metamaterials, which were named by the American Physical Society as one of the top three physics discoveries of the first decade of the new century. His work comprises theoretical studies, full-wave electromagnetic simulations, and experiments on a unique automatic microwave field mapping fixture, which he helped to develop and advance.” Overall, during his PhD studies, Navid has authored and co-authored 4 journal papers, 4 more papers are in preparation. He has also authored and co-authored 5 published refereed conference proceedings and made two presentations at the IEEE International Symposium on Antennas and Propagation, the major forum in the field.

The ECE Department congratulates Aref and Navid and appreciates their many contributions to the department, university, and their field.
