This is a multi-disciplinary conference based on the wide range of

applications of work related to or inspired by that of Ray Solomonoff.

As well as “artificial intelligence”, “machine learning”,

“statistics” and “philosophy”, it is clear that the categories

as keywords for this conference should also include (e.g.)

“mathematics”, “linguistics”, “AI”, “computer science”,

“data mining”, “bioinformatics”, “computational intelligence”,

“computational science”, “life sciences”, “physics”,

“knowledge discovery”, “ethics”, “computational biology”,

“computational linguistics”, “collective intelligence”, etc.

Ray Solomonoff (1926-2009) was the originator (in 1964) of algorithmic

information theory. Solomonoff’s (1964) work preceded the slightly

later independent work of Kolmogorov (1965) [from whom we have the term

Kolmogorov complexity], shortly before the not unrelated work of the

then teenage G. J. Chaitin (1966). But, unlike the slightly later

Kolmogorov and Chaitin, Solomonoff (1964) also saw the relevance of this

new area to statistics, machine learning, artificial intelligence and

prediction – and coined the term algorithmic probability (ALP). Given

a body of data, the algorithmic probability distribution behind

Solomonoff prediction is obtained by doing a posterior-weighted averaging

of the outputs of all available computable theories – with the prior

probabilities of theories depending (monotonically decreasingly) upon the

lengths of their encodings on the chosen Universal Turing Machine (UTM).

Independently of and shortly after the above was the Minimum Message

Length (MML) work of Wallace and Boulton (1968), based on very similar

Bayesian information-theoretic principles but instead focussing on the

one single best model for statistical and inductive inference (and

whose relationship with algorithmic information theory was formalised

in the 1990s). The related Minimum Description Length (MDL) principle

followed a decade later in Rissanen (1978), co-incidentally taking the

same form as Schwarz’s (1978) Bayesian Information Criterion (BIC) of

the same year – and with some approaches [such as the still popular

but largely unrelated Akaike’s Information Criterion (AIC)] formed

after MML but before MDL. The (algorithmic) information theory behind

both Solomonoff prediction and (the two-part form of) MML inference

(or model selection and point estimation) leads to a variety of

statistical consistency (or convergence) results – apparently more

general than for other approaches – and likewise makes the results of

both approaches statistically invariant to re-parameterisation.

These approaches – both the MML inductive or inferential approach to

choosing the single “best” model and the Solomonoff predictive

approach of weighting over the posterior to form a predictive

distribution – are two of at least as many approaches from (Kolmogorov

complexity or) algorithmic information theory which have been applied

to a range of areas. Such areas include (e.g.) statistical inference

(and model selection and point estimation) and prediction, machine

learning, econometrics (including time series and panel data), in

principle proofs of financial market inefficiency, knowledge discovery

and “data mining”, theories of (quantifying) intelligence and new

forms of (universal) intelligence test (for robotic, terrestrial and

extra-terrestrial life), philosophy of science, the problem of

induction, bioinformatics, linguistics, evolutionary (tree) models in

biology and linguistics, geography, climate modelling and bush-fire

detection, environmental science, image processing, spectral analysis,

engineering, arguments that entropy is not the arrow of time, etc.

Of course, this list will continue to grow and is not exhaustive.

Perhaps Solomonoff’s next main contribution was the notion of

“infinity point” (Solomonoff, 1985), later referred to as the

“singularity”, where machine intelligence catches up to and

overtakes human intelligence – an increasingly discussed scenario

which forms the basis of many science fiction films.

In the year in which Ray Solomonoff would have had his 85th birthday and

some weeks before the year in which Alan Turing (upon whose Universal

Turing Machines much of Solomonoff’s work is based) would have turned

100, this multi-disclipinary conference is timed for late 2011. It also

follows on 15 years after the Information, Statistics and Induction in

Science (ISIS) conference in 1996 and also held in Melbourne, Australia

– whose invited speakers included Ray Solomonoff, (Turing Award winner

and fellow artificial intelligence pioneer) Marvin Minsky, Jorma Rissanen

(of Minimum Description Length [MDL]) and (prominent machine learning

researcher) J. Ross Quinlan.

The contributions sought for this Solomonoff 85th memorial conference

are the abovementioned themes and/or anything (else) directly or at

least indirectly comparing with or building upon Solomonoff’s work.

This inter-disciplinary conference will be held in Melbourne, Australia.

The conference will run for three days, from Wedn 30 November 2011

to Friday 2 December 2011, but might possibly be preceded by a day

or half-day of workshops and/or tutorials on Tues 29 November 2011.

Conference proceedings will be fully-refereed and published with a

suitable prestigious publisher. Selected papers on suitable topics

might be chosen to be expanded upon for journal special issues.
