The Things about Job Title

[My original post from linkedin https://www.linkedin.com/pulse/things-job-title-zan-kai-chong/%5D

Switching from the job title data scientist to machine learning engineer amuses a lot of my friends. They wondering since when I become a lecturer again (note : machine “learning”). Despite my wrongful explanation, I start thinking what is my real job title other than those words printed on my name cards.

Analytically, I should list down all my job functions. Then build the heat map or histogram from all the words in the description and then identify the common words by applying the max(count) or corr function. Okay, sounds right. Here we go.

First, I work on AWS platform. As a trustworthy power user, I stress-test the costly computing instance and provide my helpful IT support to new comers (lady is preferable). I also use EMR (very expensive computer clusters) like-a-boss occasionally for big data stuff. Occasionally, I speak AWS jargon as if I am real AWS engineer.

Okay. You saw the word “big data”. Of cause , I am (acting like) a big data engineer as I work on peta-ful (new word to describe peta bytes) data. These petaful data are our asset to track you. We may not be as good as Cambridge Analytica. But we know many things about you and what you did last weekend. The more you attach to your phone, the more we know you.

In short , it is fun to work in analytics company. Well, my real job title? I am wondering as well . Perhaps , I should just call myself “engineer“.

I was in a great self-involved until my civil engineer friends start mocking me with a photo.

Venturing into Data Science

After seven years of academy life at UTAR, I decided to move on to the data science industry to explore the opportunity in big data transformation.

It is a hard but necessary move to me. I will leave the full story to offline face to face discussion if our frequency and space-time are right.

Here are my observation after six months working in data science industry. Majority of Malaysia industries are business-driven entities — business comes first and research be the second (or last). Usually, R&D or r&D departments are hardly survive in the evolution (a.k.a company restructure / reorganization) considering the output are always less convincing in the board meeting. One of the common practice is to embedded the R element as part of the product development such that some tangible output are there.

Another interesting thing is, the term research varies a lot in industry. It can refer to operational research, product research, applied research, etc. Definitely it is not the research that allows you to sit down to for the whole month just to derive an elegant but less useful equation to them.

After all, I am the  latter type of person. I guess it gonna takes another few months before my boss realizes that I am working on a niche research topic instead of building the requested machine learning model.

 

Hire Research Assistant

We are looking for ONE candidate that is

  • Good in programming, mathematics, microcontroller system, and principle of network communication.
  • Good command of English
  • Discipline and independent

to work with us to improves the performance of Internet-of-Things (IoT) with locally decodable code. The successful candidate will be paid with RM 2,500 for 12 months and renewable to another year (1+1 policy). He/She is expected to register for Master of Engineering Science in Lee Kong Chian Faculty of Engineering Science (LKC FES) and complete the study in 24 months.

Knowledge in network communication and coding theory are preferable, but not a must. The successful candidate must register for Master of Engineering Science in Lee Kong Chian Faculty of Engineering Science (LKC FES).

BRIEF DESCRIPTION OF THE PROJECT

We consider a mobile wireless sensor network (MWSN) that consists of thousands of static sensor nodes with one or multiple mobile sinks (mobile base stations). Such dynamic network is commonly found in the IoT applications such as users with wireless wearable devices walking on streets or shopping at outlets – the wearable devices acting as the mobile sinks that continuously fetching the environment sensory data in order to provide ubiquitous services to users.

The candidate will work together with the team to design the communication protocol, implement the testbed on Raspberry Pi, etc. Minimum logistic work may be required.

The team members are Dr. Chong Zan Kai, Prof. Ir. Dr. Goi Bok Min, Prof. Ir. Dr. Ewe Hong Tat, Dr. Lai An Chow and Dr. Goh Hock Guan and Ms. Tan Lyk Yin. This is also a collaboration project with researchers from Kwansei Gakuin University, Japan and Victoria University of Wellington, New Zealand.

The interested candidates should send their resumes to Dr. Chong Zan Kai chongzk@utar.edu.my.

Calling for Research Assistant at UTAR

We are looking for ONE candidate that is

  • Good in programming and mathematics
  • Willing to learn
  • Good English
  • Discipline and independent

to work on a research project that improves the future network throughput with computer accelerator. The successful candidate will be paid with RM 2,500 for 12 months (renewable to another year). Knowledge in parallel processing and coding theory are preferable, but not a must. The successful candidate is expected to register for Master of Engineering Science in Lee Kong Chian Faculty of Engineering Science (LKCFES). LKCFES FYP-2 students are encouraged to apply.

Description of the Project Rateless erasure code is a kind of error-correction code, where the original message can be reconstructed from the fractional encoded message. The emergence of rateless erasure code promises a better network throughput, but constrained by the bottleneck in the corresponding encoding and decoding speed.

The candidate needs to improve the encoding and decoding speed of the rateless erasure code with graphical processing unit (GPU) and to apply it in network communication. Some logistic work may be required.

The team members includes Chong Zan Kai, Prof. Goi Bok Min, Prof. Ewe Hong Tat, Dr. Lai An Chow and Yap Wun She.

The interested candidates should send their resumes to Chong Zan Kai chongzk+ra@utar.edu.my.

Tutorial on Sage mathematics software system / Python Programming

Dear UTAR Students,

I am giving a 3 hours tutorial on Sage on the coming Friday (23-Jan-2015), 10am-1pm at SE203 computer lab.

Sage (http://www.sagemath.org/) is an open-source mathematics software system that is derived from Python programming language. Unlike C / C++programming , Sage enables the users to focus only on the problem solving instead of dealing with the computer resources and settings (e.g. memory architecture, pointers, variable types, brackets etc.).

Basically, the tutorial is meant for the students of UEET2533 Information Theory and Coding to kick-start their assignment. Following the common practice in teaching this subject, the tutorial will be opened to public (UTAR). Students from other courses are welcome to join as the tutorial will be general enough for all the students with little knowledge in C programming (not a must, though).

We will do the programming using the cloud service at http://cloud.sagemath.org and the slides can be found in http://1drv.ms/1ynqb4r . We will spend the first hour to learn programming in the cloud; the second hour on the syntax and control logic and the last hour on solving some simple math problems (e.g. 1+1=2).

No registration is required but do let me know if you are coming as the computer lab can only accommodate limited number of students.

Let’s have fun in programming!

Circuit Theory 2014 May – Teaching Summaries

  I start writing summaries for my daily teaching in UTAR and posted them in our dedicated Facebook group.

  I not really sure if the students will appreciate the summaries. But I do think* that they can use the summaries to recap what have been delivered in that the class while they are asleep. To me, these summaries can re-explain and re-clarify some concepts, which I have badly explained in class.
