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

Publishing or perishing 3

Following this previous post, I've found a few more articles about the dismissal of staff from the University of Sydney, for not publishing at least four papers in three years. This article is scathing of the university management, while Alex Burns, in this post, is in a similar vein to what I wrote: that four papers in three years is not an excessive number and that most academics should be able to meet it.

The most interesting post I found was this one, from David McGloin at the University of Dundee, where he lists a number of reasons someone might not reach the target number of publications. This is useful, as it informs as to what strategies academics could follow to avoid finding themselves in this sort of situation. Below, I reproduce each of his points, along with my responses:

It could be that you’re on the brink of some big breakthrough and the focus of this has taken many years to complete.

It is very dangerous for any academic to focus on one project to the exclusion of all others. Also, any project can be broken up into small, publishable chunks. That is, rather than writing up a single magnum opus of a paper at the end of the project, one should publish several smaller papers during the course of the work. This is more likely to make funding agencies happy as well, as it shows them that you are being consistently productive.

It may be that you’ve had bad luck with papers getting accepted, or have been doing good work, but maybe aiming to high up the journal league table.

Reformatting a rejected paper for another journal doesn't take very long. Waiting for reviews takes a long time (six months or more for some of my papers) but again, no academic should be working on just one project at a time. Everyone gets a period of bad luck with getting papers accepted (I had a long string of rejections throughout 2010 - I made up for it in 2011). The important thing is to have more than one project on the go at any one time, and to have a fast turn-around on rejected papers. If you follow a journal article submission strategy similar to the one I suggest, you should already have a good idea of other journals you could submit to.

It could be that you have had a run of poor luck on grant funding, and have not had the support to do your work and write up results, in terms of PhD students, postdocs, or simply a lack of equipment.

I do tend to agree with this point, especially for fields that need a lot of equipment to get results. I will point out, though, that having a good publication record will help with getting research grants.

Maybe a series of experiments didn’t work, but the next one will (and it will win a Nobel Prize).

Again, it is very important to pursue more than one research project at a time. That way, if one set of experiments doesn't work out, you can still publish the results from another.

Maybe your research output is highly subjective (think works by artists) and the critics didn’t like your last show.

This is more of a problem for researchers in the humanities. As a scientist I can't really comment on this, other than to point again to my responses above.

Maybe your research rivals knew about your employment conditions and decided to reject your last paper (to make it to the magic four) to get you sacked.

This is the most frightening point. Not only is such behavior completely unethical, it undermines the entire peer-review process. Anyone engaging in such  behavior - rejecting papers just because the author is a rival - should be sacked immediately. If this does happen, it is also a failure on the part of the journal editors. Most journal submission systems allow the authors to list reviewers they are opposed to. Any editor who sends a paper to a reviewer who they have reasonable suspicion is a rival of the author, is failing to do their job.

Or maybe, just maybe you didn’t feel the need to publish every last little bit of work to avoid saturating the journals and keep the overall quality of published work high enough to make it bearable to read them.

This is a non sequitor. Submitting a lot of papers does not mean a lack of quality in the papers. As I mentioned above, you can break your project up into smaller, publishable chunks and submit a paper on each. Planning your research program is an essential skill for the professional researcher. Also, if the quality of the paper is so low that it's unreadable, how would it get published to begin with?

Maybe you published one Nature paper a year over the last three years and nothing else, and they each got 500 citations

This is one of those situations that could occur, but is really unlikely. The people I know who do publish in Nature, are the people who publish 20+ papers (journal articles) per year! I really can't see how anyone could be good enough to publish three papers in a row in Nature yet not be good enough to get one more paper published in another journal.

Publish or perish is the rule of academia, and has been for a long time. Sensible and positive ways you can publish without perishing are:

• pursuing more than one research project at a time 
• collaborating widely (this is pretty easy to do in computational intelligence, as our algorithms are so widely applicable 
• breaking your research into small, publishable chunks 
• rapid turn-around on rejected papers 

It is time that the non-publishing staff at universities were put on notice to start producing. I know of more than one university computing department where the combined journal article output for all staff in 2011 was less than my own output. Why do these people have safe, permanent jobs, when so many young, productive researchers don't?

Publishing or perishing 2

Or, big trouble in little USyd.

In a previous post, I discussed the principle of "Publish or perish". This phrase is a succinct way of saying that the most important metric by which an academic is judged, is their publication record: those who do not publish enough will not be valued as highly as those who publish more. Recent developments in Australian academia have made this literally true.

The University of Sydney is dismissing 100 academics who have not published at least four times in the last three years. Early career researchers are apparently exempt from this threshold, so it is only senior academics (presumably permanent staff members) who are at risk. In other words, they are in senior positions, yet they have not published, so they are perishing.

To put that number (four papers is three years) in perspective, I'm not a permanent staff member, yet in the last three years I've published fifteen times, and have more than a dozen publications in the pipeline (I expect to publish them this year). While I am currently full-time research, I have taught full-time in the past, yet I still managed to publish research. During my final year teaching, I published papers, was finishing my PhD, and taught / administered two undergrad courses. I got married that year, too.

The only thing that garners any sympathy from me is that claims are being made that late last year academic staff were told that an average publication rate of 0.8 per year (four papers in five years) would be satisfactory. If that is true, then management have moved the goal-posts, which strikes me as rather unfair. However, even when I was working as a post-doc at the University of Sydney, I was expected to produce at least two papers per year. In my current position, my target output is at least six per year (I got ten last year, and I'm on track to get twelve this year - the best way to meet a target, is to aim to exceed it). Did senior lecturers really think they could get away with less? "Publish or perish" is a very old saying.

Now, the University of Sydney is taking this action to make up for a massive short-fall in income (the exact reasons for this sudden short-fall are rather murky) but what would the effect be if this hard form of publish or perish were enforced more often at universities? It might have the effect of sweeping out those academics who have become complacent in their positions, or who are approaching the end of their academic careers (that is, they are no longer capable of performing research at the level required). This would in turn free up positions for younger staff, who are capable of producing publications, yet can't find permanent positions because they're being held by unproductive senior staff. Are there any other professions where those who do not perform, get to keep their jobs? Of course not. A major part of being an academic is publishing: if you're not publishing, you're not doing your job. If you're not doing your job, do you deserve to keep it?

On a humane level, I'm sorry for the people who are losing their jobs. But honestly, I wish this standard were applied at more universities.

Using MLP to model the distribution of bacterial crop diseases

A new paper I co-authored with Sue Worner at Lincoln University is now available and describes how we used MLP to model the global distribution of bacterial crop diseases.

We had data on the presence or absence of certain species of bacterial crop disease (that is, bacteria that infect and cause diseases in plants we use as crops) in 459 geo-political regions throughout the world. We also had data on the climate in these regions and the presence of host plant species. We created MLP that predicted the presence or absence of the bacteria species from climate (abiotic factors). We also created MLP that predicted the presence or absence of the bacteria species from the host plant species assemblages (biotic factors). While both of these approaches worked, we got much better accuracies by combining the outputs into ensembles, and by using a cascaded or tandem ANN approach.

Ensembles are a way of combining the outputs of several ANN. An input vector is propagated through each of the ANN, and the output values combined either statistically (the final output value is the max, mean or median of the uncombined outputs) or algorithmically (output is determined as a majority vote of the uncombined outputs - that is, if the majority of the values is above a threshold, the output of the ensemble is a presence, otherwise, absence). We looked at three different kinds of ensemble: firstly, ensembles of the best ten MLP trained on abiotic inputs; secondly, ensembles of the best ten MLP trained on biotic inputs; and finally, ensembles that combined the best ten MLP trained on abiotic input as well as the best ten MLP trained on biotic inputs. These last ensembles were particularly interesting, as it allowed us to make predictions of species distributions using both biotic and abiotic factors simultaneously. The rationale behind ensembles is that different MLP learn different parts of the problem space: by combining the outputs of several MLP, it is possible to cover a larger part of the problem space, and therefore to boost prediction accuracy. Combining abiotic and biotic factors is the same idea. We know that an organism is affected by both of these factors, so combining both of them allows us to make more accurate predictions.

While the ensemble approach boosted the prediction accuracies, we thought we could do better, so we created MLP that took as inputs the outputs of the very best MLP trained on abiotic and biotic factors. In other words, the outputs of the climate and host networks were used as the input values for a second-level of MLP, which were then trained on the presence and absence of the bacteria species. The idea behind tandem ANN is that, if a first-level network makes a mistake - that is, if a climate or host MLP makes an incorrect prediction - then the tandem network can learn to correct it. Again, we were combining abiotic and biotic factors to make predictions.

The results of all these techniques were that while the single-level MLP were able to predict the distributions of the crop diseases fairly well, combining abiotic and biotic factors gave much better accuracy, whether the combination was achieved by a simple ensemble approach, or by using a tandem MLP approach.

This paper is published in Computational Ecology and Software, an open-access journal. Given my previous posts extolling the virtues of open access journals (see here, here, here and here) I'm putting my academic money where my mouth is, and submitting to open-access journals.
