CfP: IEEE WCCI 2012 Special Session on Fuzzy Ontologies and FML Applications

We would like to invite you to submit a paper for a special session "Fuzzy Ontologies and Fuzzy Markup Language Applications" at the Fuzz-IEEE 2012 conference which will be held as part of the 2012 IEEE WCCI in Brisbane, Australia at June 10-15, 2012.

It is widely pointed out that classical ontology is not sufficient to deal with imprecise and vague knowledge for some real world applications like personal diabetic diet recommendation. On the other hand, fuzzy ontology can effectively help to handle and process uncertain data and knowledge. Recently, the research on the ontology has been spread widely to be critical components in the knowledge management, Semantic Web, business-to-business applications, and several other application areas. Ontologies are a suitable way for representing complex knowledge and facilitating knowledge share and reuse. The concept of ontology has been widely embraced by the fuzzy research community by playing an important role in the development of distributed systems and the composition reveals a vital strategy for enterprise collaboration. In this context, the Fuzzy Markup Language (FML) is one of the most important results because it allows fuzzy scientists to express their ideas in abstract and interoperable way by improving their productivity and, at the same time, increasing the average quality of their works. This special session invites high-quality conceptual, analytical and empirical articles representing intelligent agent and knowledge mining information systems and their integration. The objective of the proposed special issue is to highlight an ongoing research on fuzzy and FML approaches for ontology applications as well as their applications on various domains.

Topics of interest (not limited to):

• Ontologies and Ontological Agents 

• FML Agents for Software Engineering

• FML Agents for Knowledge Discovery 

• FML Agents in a Neuro Fuzzy Approach

• Environment-aware Agents

• Agents for Intelligent Manufacturing Systems

• Intelligent Agent Applications

• Knowledge Representation with Ontology

Common grammatical errors

English is the result of Norman soldiers attempting to pick up Anglo-Saxon barmaids, and is no more legitimate than any of the other results. - H. Beam Piper

Despite the murky origins of the English language, it is the language of international commerce and science: if you attend an international conference in, for example, China, the presentations and proceedings will be in English. The same applies to the international scholarly journals. Being able to communicate effectively in English is therefore essential for anyone who wants a good career in academia.

Now, if you ever heard me speaking, you'd have probably have trouble understanding me: my New Zealand accent means that I flatten my vowels, my voice is nasal, and I speak too quickly. But, I do write fairly well, and I do avoid the grammatical errors below that really annoy me. Don't feel too badly if you aren't a native English speaker and make these mistakes: I noticed most of these mistakes while teaching New Zealand undergrads. That is, these are the kinds of mistakes that native speakers make in some parts of the world. They're still mistakes, though, and should be avoided.

1) Reversing imply and infer. For example "What are you inferring by saying that?". An inference is made from an implication. That is, the implication is made, then the inference is drawn from it. For example,  someone once said to me: "Are you inferring I'd lie?", to which I replied "No, I'm implying you'd lie - you are inferring it". I know, I'm a bad, bad man.

2) Following from that is the distinction between implicit and explicit. If something is implicit, you know about it through inference. If something is explicit, it is stated. Saying that something was "explicitly implied" (and I have seen that written, but a university student no less) is not just bad grammar, it is complete nonsense. If something is explicit, it cannot be implied.

3) Literally means what you said is as it actually is. If you were to say "it is literally raining cats and dogs", then cats and dogs should be falling from the sky. Jamie Oliver is particularly bad for abusing this word: "and you literally put the mint in the mixture..."!

4) Your and you're. "Your" means it belongs to you. "You're" means you are. Can you see what is wrong with this picture?

Dear Tick Tax: this is your sign, and you're using incorrect grammar.

5) Using the term "begs the question". The original meaning of this is to assume as true something that cannot be taken for granted. The more correct way to saying this is "raises the question". This is probably a lost cause now, as the incorrect meaning of begging the question is widely established.

6) Its and it's. It's is short for it is. Its means something belongs to it. For example: "I saw a dog and said "it's wagging its tail"".

7) There, their and they're. There is a place. Their means something belongs to them. They're means they are. Example: "They're at their house, which is over there".

These are the errors that annoy me the most. For two excellent articles on common errors in academic writing, see "Don't torture your reader" parts I and II, by Professor Corey Bradshaw at the University of Adelaide.

Google Scholar Citations

Google has just launched a useful tool for academics: Google Scholar Citations. This is a service on top of Google Scholar that allows you to track the number of citations each of your publications has received. One of the metrics by which academics are judged is the number of citations their publications have received, the theory being that good and useful papers will be cited more than papers that are not useful, or good. This has been encapsulated by measures such as the h-index: to have an h-index of n, you must have at least n-papers that have been cited at least n-times each. It is useful for things like grant applications to be able to quote the number of citations you have received and your current h-index, insofar as convincing the grants committees that you can do the work you propose.

It was possible to track citations with Google Scholar in the past, and to calculate your h-index manually, but this could be a bit laborious and error-prone: Scholar Citations makes it a lot easier. I was impressed to see that even with a common name like mine (there are a lot of Michael Watts in the world, and some of them are also academics) the software found almost all of my publications - there are a few that aren't available online yet - and to find the citations to them. I was quite pleased to find that I had a few more citations than I thought.

Call for papers: Applications of ECoS

Special issue of Evolving Systems on

Applications of Evolving Connectionist Systems

Guest Editor

Michael J. Watts
University of Adelaide, Australia
mjwatts@ieee.org
 

Scope

The topic of this special issue is “Applications of Kasabov’s Evolving Connectionist Systems”.

In modern society, the volume and rate of data production are huge and set to increase. To process and utilise this avalanche of data, methods are needed that can rapidly and accurately model it as it becomes available. These models must be able to learn throughout their lifetimes, without forgetting what they have previously learned, and be able to explain themselves.

Kasabov’s Evolving Connectionist Systems (ECoS) are able to fulfil each of these requirements. They are a class of constructive neural networks that learn via structural growth and adaptation. They have a fast, one-pass learning algorithm, where all that can be learnt from the data is learned in the first training pass. Because of their open structure, they exhibit continuous, life-long learning whereby the structure expands as necessary to accommodate new data. Finally, they have a strong resistance to catastrophic forgetting following additional training on new data.

Examples of ECoS networks include the Evolving Fuzzy Neural Network (EFuNN), which was the first ECoS network published and is characterised by embedded fuzzy logic elements. There is also the Simple Evolving Connectionist System (SECoS), which is essentially an EFuNN with the fuzzy elements removed, and the Dynamic Evolving Fuzzy Inference System (DENFIS) for discovering Takagi-Sugeno style fuzzy rules. Many ECoS networks use fuzzy rule extraction algorithms that allow for the explanation of what the networks have learned, in a comprehensible manner.

ECoS networks are well suited to applications that are dealing with new data continuously and that have dynamic, time-critical aspects. Previous applications of ECoS include:

• Stock market prediction and macroeconomic modelling
• Speech recognition, especially multi-speaker speech recognition
• Bioinformatics and medical modelling
• Image and video parsing
• Robot control
• Information system security

The special issue is concerned with all aspects of the application of ECoS networks to real-life problems and data sets. Topics of interest include, but are not limited to:

• Applications of ECoS to real-world problems
• Data mining of complex data sets using ECoS
• Comparisons of ECoS with other algorithms over real-world data sets
• Modifications of ECoS algorithms to fit them to real-world problems

Hang in there

A wise person once told me that doing a PhD is as much a test of endurance as it is a test of intelligence. You face years of late nights, mountains of literature, numerous false-starts and dead-ends, and the nagging fear in the back of your mind that it might not be all that worth it.

Whether or not it is worth it is a question that only you can answer. Financially, it probably isn't. People who do PhDs tend to earn less over their lives than those who do not. They take longer to settle down and tend to delay parenthood and home-ownership until later in life. On the other hand, a PhD is your ticket into academia: the chances of getting a good, stable academic position without a PhD are, now, practically nil. A PhD can also gain you respect from the community: although I seldom use my title, it is useful when I do. Finally, there is the satisfaction of knowing that you achieved something most people never will, or never could. Personally, I did a PhD because I wanted to see if I could. It was the challenge of doing it that appealed to me. With my undergrad degree (first class honours in Information Science) I could have gone into the corporate world and made a very good living. I'd probably be in a high management position now, making a lot more money than I am making as a researcher, but I'd probably be miserable at the same time, because I'd never know how far I could have gone in research. And at the end of my life, I'd be asking myself, how much of a difference did I really make?

There are several factors that contribute to a successful PhD. Firstly, you must have a good supervisor. In fact, I'd go as far to say that you need two supervisors, one senior and one junior. By that I mean that you need one supervisor who is an established academic who is well-respected in their field, and another supervisor who has recently completed their PhD. This is because the junior supervisor still remembers what it is like to do a PhD in the current time, while someone who did their PhD twenty years ago has probably forgotten. You must actively engage with your supervisors, to make sure that they are up-to-date with what you are doing and what you plan to do. A supervisor who is ignorant of what you are doing is a useless supervisor. Don't keep them in the dark!

You must have a clear idea of what your PhD is about. In other words, you must have a hypothesis, and research questions, and research goals. I even went so far as to make these explicit in the introduction to my thesis. It might take you a while to be clear about these, but you'll save a lot more time in the long run.

You must not underestimate the requirements for a PhD. Most universities award a PhD for "a significant original contribution to knowledge" (although most of them do not define "significant" "original" or "contribution"). So, a new algorithm for determining the contributions of the input variables of a neural network probably wouldn't be enough for a PhD, while the algorithm in the context of a rigorous theoretical analysis of the neural network itself, along with an analysis of the algorithm, probably would.

You must not over-estimate the requirement for a PhD. In other words, you're not going to find a cancer cure, or discover the Higgs boson, or bring peace to the Middle East during the course of your PhD. Your PhD research problem needs to be enough for a PhD, and no more. Feature-creep kills PhDs as easily as it kills software projects. From chatting with more senior academics, I've come to believe that this is a more common problem than underestimating a PhD. A good supervisor will help you define the scope of your PhD project, while a bad supervisor will not. Get rid of a bad supervisor and find a better one. Or, at least seek help elsewhere.

You must stick with it. Everyone has a period during their PhD when it all looks hopeless, when you don't want to go on and just want to pack it all in. Hang in there. If you've decided that it's worth it before starting your PhD, it probably is still worth it, even if you don't feel like it. The enormous high you will get when you pass your examination is something  you'll not feel often in your life (I found out I had passed my PhD examination two weeks before becoming a father, so I had all of my enormous highs in a short period of time).

It is likely that your examiners will want you to make some revisions to your thesis. Don't take this personally! The best thing to do is to just shut the hell up, make the changes as quickly as you can, and get the degree confirmed. Don't waste too much time arguing with the examiners, unless they are egregiously wrong (one of my examiners was egregiously wrong, in several places, and making the changes he wanted would have made my thesis worse, not better. In the end, I had to show my examination convener a pile of literature that showed that the examiner was wrong, and educate him on how innumerate the examiner was).

When you have passed your PhD exam, the next step is to get a job. If you want to be an academic, that means getting a post-doc. If you're organised, or lucky, then you might even have a post-doc organised before you finish your PhD. Don't restrict your search to just the field you did your PhD in. My PhD was in computational intelligence, but my two post-docs were in ecological informatics, and my current position is in ecological modelling. I'm not an ecologist, by any stretch of the imagination (although I do know a lot about ecology now) but because I am a flexible and fairly clever person I was able to work in these fields, and work effectively. Know what skills you have, and know how to advertise them to potential post-doc supervisors.

Once you're in a post-doc position, the only goal you should have is to publish as many papers as you can, as widely as you can and as quickly as you can. It can also be good to co-supervise some PhD students of your own, to attend conferences, edit journal special issues, and generally show the world that you are a good, hard-working and professional researcher.

But, above all, you must hang in there!

Cargo Cult Statistics

One of the nice things about working in a world-class ecology group is the statistical rigor with which ecologists analyse their results. Unfortunately, this rigor is often missing in computational intelligence. Although I touched on some of these issues in a previous post on Minimum requirements for computational intelligence papers, I recently read an article (that shall remain anonymous) that actually made me groan. While I am starting to notice more papers with repeated trials, and even investigating several parameters, the analysis of these results leave a lot to be desired.

Sometimes it is enough to simply list the mean and standard deviation of your accuracy measures. By itself, the mean is useful as a statistic that represents the population of accuracies that the algorithm yielded. The standard deviation is also good as a measure of spread of the values. But if your standard deviation is large, that needs some comment in the paper on why the algorithm is so variable? This is even more important when comparing different algorithms. An author might for example like to say that a neural network trained with evolutionary programming is better than logistic regression for their application, but if they are seeing a coefficient of variation of more than 60% then that implies that the algorithm is giving highly variable or even inconsistent results. To say that these results show that ANN are better than regression, without any statistical tests for significant differences is simply nonsense.

Even if you do do such tests, you need to make sure that you are using the correct tests. What is the distribution of your results? Are they normally distributed? If they are not normally distributed, then you can't use simple parametric tests of significant differences like t-tests. If you are comparing several groups of numbers then a n-way ANOVA is more appropriate than performing n t-tests. These kinds of comparisons, of several groups of numbers, are very common in computational intelligence (the authors are comparing different algorithms over several data sets, or with different parameterisations) but I can't remember ever seeing a paper that mentioned ANOVA (if you can prove me wrong, please do so in the comments).

I call this kind of shallow statistical analysis Cargo Cult Statistics.The term is inspired by Richard Feynman's famous speech about Cargo Cult Science. In this case, it means that while it looks like the authors are doing a statistical analysis of their results (they are calculating the means and standard deviations) it isn't really so, because they are missing out a huge amount of analysis that might actually tell them something useful about their results.

Now, I'm still learning about statistics (but, I'm still learning about everything, and will be until the day I die). But at least I know to ask someone with a better knowledge of statistics than me for advice on how to analyse my results, and I think it makes my papers much better.

Open research problems with Evolving Connectionist Systems

I described Evolving Connectionist Systems (ECoS) in an earlier post. A couple of years ago, I published a review article (PDF preprint) where I described the state of the art of ECoS, and identified several open research problems. There hasn't been much progress made in solving these problems, so I'm going to briefly describe them here, and hopefully stimulate a bit more work in this area. Of course, I'm doing a bit of work in some of these, but as I have a real job to do, I don't get as much time to spend on these problems as I'd like.

1) Input significance. With other ANN, especially the venerable MLP, it is possible to get an indication of how important each input variable is to the model. These methods are based on an analysis of the magnitude of the connection weights attached to each input neuron. This method won't work with ECoS networks, however, because the connection weights represent points in space. That is, the magnitude of the weight for an input neuron connection has nothing to do with how important that input is.


2) Optimisation of ECoS networks. While ECoS algorithms are fast learning, they can grow to be quite large, which makes them expensive in terms of memory and computational load. Ideally, it would be possible to reduce their size without sacrificing their accuracy. That is, it would be ideal if we could somehow eliminate redundant information in the ECoS and only retain that which is necessary for maintaining accuracy. I investigated a couple of methods of doing this in my PhD, and a few other people have looked at it as well, but no one has yet cracked the problem in terms of coming up with an optimisation algorithm that will significantly reduce the size of a trained ECoS network without significantly reducing its accuracy. Also, the most effective optimisation methods in the published work use evolutionary algorithms like genetic algorithms or evolution strategies. These are so computationally intensive that the speed advantages of ECoS are lost. An ECoS optimisation algorithm would ideally be as fast, or nearly as fast, as the ECoS training algorithm. It may be that this is inherently impossible.

3) Non-triangular fuzzy membership functions in EFuNN. The Evolving Fuzzy Neural Network EFuNN has triangular fuzzy membership functions (MF) embedded in its structure. These are fast and efficient, but other MF types (such as Gaussian) may be more useful for other applications.

4) Learning in the MF of EFuNN. The fuzzy MF in EFuNN are fixed, that is, they are set once and do not change during the life of the EFuNN. This is in contrast to the open, adaptive nature of EFuNN itself. An extension of the EFuNN learning algorithm that would allow the MF to adapt as the rest of the network adapts, would be extremely useful for data mining applications. This algorithm would have to be as fast as the rest of the EFuNN learning algorithm, which may rule out backpropagation training of the MF, as is used in other fuzzy system optimisation.

Although ECoS networks are very useful algorithms, they could be made even more useful if the problems above were solved. I'm working on some of them, but I would love to see others working on them as well. Contact me if you are interested in collaborating.
