Introduction The start of my research:  M.Eng.: Digital Communications  PhD: Discrete Transforms What I think of “PhD”?  An Expert in one defined area  Ability to conduct independent research  Contribution to the defined area  Evidenced by SCI journal publication Target I set for my students  3 IEEE Transactions Papers  Or at least  1 IEEE Transactions Paper + 2 SCI Journals 8

How to do Research? (1) Define Research Direction / Area First of all, Read and Understand last 3 years journals/conferences in the defined area (and the associated references)  Start with flagship conferences  Then move on to top tier journals  Write a summary/PPT for every paper read 9

How to do Research? (2) You should have first idea after reading and understanding 30-50 papers Using the idea, implement and test and compare performance with 3 previous best Generally, for PhD you will need to read 150-300 papers Contribute 3 ideas significant enough to be accepted/published in IEEE Transactions, and you are done! 10

How to do research? = 5W+1H is the problem we are studying? will the solution be used? What… Where… have contributed in the past? method is metric-superior? Who… Which… Why… previous solutions are not good enough? How… we are going to do it better? 11

How to write a research paper? What… is the problem we are studying? Where… will the solution be used? Who… have contributed in the past? Which… method is metric-superior? Why… previous solutions are not good enough? How… are we better? 12

Is Mathematics important? Depending on the field, generally, Yes. 13

Impact Factor Definition: Citations = number of times that the papers are cited. Publications = number of research papers produced. Source from Wikipedia 14

H-index The definition of the index is that a scholar with an index of h has published h papers each of which has been cited in other papers at least h times Source from Wikipedia 15

G-index The index is calculated based on the distribution of citations received by a given researcher's publications, such that given a set of articles ranked in decreasing order of the number of citations that they received, the g- index is the unique largest number such that the top g articles received together at least g2 citations. Source from Wikipedia 16

i10-index i10 index refers to the number of paper with 10 or more citations Source from Wikipedia 17

Some other ways to compute - 1 • Papers • Total Papers is the total number of papers the candidate authored or co- authored • Citations • Total number of citations for all papers that candidates authored or co- authored. • Contributions • Contributions = Papers + Citations Source from Wikipedia 21

Some other ways to compute - 2 • Papers • Total Papers is the total number of papers the candidate authored or co- authored • Weighted Paper, ௐ ଵ ஺௨௧௛௢௥ ே௨௠௕௘௥ • ௐ • Example, for a paper, author number 1, 𝑃ௐ=1 • And for author number 2, 𝑃ௐ=ଵ . ଶ ்௢௧௔௟ ௉௔௣௘௥௦ ௜ୀଵ ௐ೔ • Total Weighted Papers = ்௢௧௔௟ ௉௔௣௘௥௦ ௜ୀଵ ௐ೔ • Total Citations = ௜ Source from Wikipedia 22

Long Term Societal Impact - the real impact? Conference vs. Journal Short vs. Long Quantity vs. Quality Journal/Conference vs. Patent Citation vs. $ 24

Increasing Probability of Acceptance  How would you evaluate the quality of a paper in terms of: Novelty and Originality  Technical Content and Correctness  Relevance and Timeliness  Quality of Presentation  Quality of Experimental Results Appropriateness to Conference/Journal  Importance to the Field  Reference to Prior Work  Length 25

Two Examples 1. A paper submitted to Top-Tier Journal 2. A paper submitted to Another Top-Tier Journal But before we do that, no camera and no voice recorder please. 26
