111 %\usepackage{fixltx2e}
112 % fixltx2e, the successor to the earlier fix2col.sty, was written by
113 % Frank Mittelbach and David Carlisle. This package corrects a few problems
114 % in the LaTeX2e kernel, the most notable of which is that in current
115 % LaTeX2e releases, the ordering of single and double column floats is not
116 % guaranteed to be preserved. Thus, an unpatched LaTeX2e can allow a
117 % single column figure to be placed prior to an earlier double column
118 % figure. The latest version and documentation can be found at:
119 % http://www.ctan.org/tex-archive/macros/latex/base/
123 %\usepackage{stfloats}
124 % stfloats.sty was written by Sigitas Tolusis. This package gives LaTeX2e
125 % the ability to do double column floats at the bottom of the page as well
126 % as the top. (e.g., "\begin{figure*}[!b]" is not normally possible in
127 % LaTeX2e). It also provides a command:
128 %\fnbelowfloat
129 % to enable the placement of footnotes below bottom floats (the standard
130 % LaTeX2e kernel puts them above bottom floats). This is an invasive package
131 % which rewrites many portions of the LaTeX2e float routines. It may not work
132 % with other packages that modify the LaTeX2e float routines. The latest
133 % version and documentation can be obtained at:
134 % http://www.ctan.org/tex-archive/macros/latex/contrib/sttools/
135 % Documentation is contained in the stfloats.sty comments as well as in the
136 % presfull.pdf file. Do not use the stfloats baselinefloat ability as IEEE
137 % does not allow \baselineskip to stretch. Authors submitting work to the
138 % IEEE should note that IEEE rarely uses double column equations and
139 % that authors should try to avoid such use. Do not be tempted to use the
140 % cuted.sty or midfloat.sty packages (also by Sigitas Tolusis) as IEEE does
141 % not format its papers in such ways.

146 % \let\MYoriglatexcaption\caption
147 % \renewcommand{\caption}[2][\relax]{\MYoriglatexcaption[#2]{#2}}
148 %\fi
149 % endfloat.sty was written by James Darrell McCauley and Jeff Goldberg.
150 % This package may be useful when used in conjunction with IEEEtran.cls'
151 % captionsoff option. Some IEEE journals/societies require that submissions
152 % have lists of figures/tables at the end of the paper and that
153 % figures/tables without any captions are placed on a page by themselves at
154 % the end of the document. If needed, the draftcls IEEEtran class option or
155 % \CLASSINPUTbaselinestretch interface can be used to increase the line
156 % spacing as well. Be sure and use the nomarkers option of endfloat to
157 % prevent endfloat from "marking" where the figures would have been placed
158 % in the text. The two hack lines of code above are a slight modification of
159 % that suggested by in the endfloat docs (section 8.3.1) to ensure that
160 % the full captions always appear in the list of figures/tables - even if
161 % the user used the short optional argument of \caption[]{}.
162 % IEEE papers do not typically make use of \caption[]'s optional argument,
163 % so this should not be an issue. A similar trick can be used to disable
164 % captions of packages such as subfig.sty that lack options to turn off
165 % the subcaptions:
166 % For subfig.sty:
167 % \let\MYorigsubfloat\subfloat
168 % \renewcommand{\subfloat}[2][\relax]{\MYorigsubfloat[]{#2}}
169 % For subfigure.sty:
170 % \let\MYorigsubfigure\subfigure
171 % \renewcommand{\subfigure}[2][\relax]{\MYorigsubfigure[]{#2}}
172 % However, the above trick will not work if both optional arguments of
173 % the \subfloat/subfig command are used. Furthermore, there needs to be a
174 % description of each subfigure *somewhere* and endfloat does not add
175 % subfigure captions to its list of figures. Thus, the best approach is to
176 % avoid the use of subfigure captions (many IEEE journals avoid them anyway)
177 % and instead reference/explain all the subfigures within the main caption.
178 % The latest version of endfloat.sty and its documentation can obtained at:
179 % http://www.ctan.org/tex-archive/macros/latex/contrib/endfloat/
181 % The IEEEtran \ifCLASSOPTIONcaptionsoff conditional can also be used
182 % later in the document, say, to conditionally put the References on a
183 % page by themselves.
187 %\usepackage{url}
188 % url.sty was written by Donald Arseneau. It provides better support for
189 % handling and breaking URLs. url.sty is already installed on most LaTeX
190 % systems. The latest version can be obtained at:

273 We process a~large corpus of game records of the board game of Go and
274 propose a~way to extract per-player summary information on played moves.
275 We then apply several basic data-mining methods on the summary
276 information to identify the most differentiating features within the
277 summary information, and discuss their correspondence with traditional
278 Go knowledge. We show mappings of the features to player attributes
279 like playing strength or informally perceived "playing style" (such as
280 territoriality or aggressivity), and propose applications including
281 seeding real-work ranks of internet players, aiding in Go study, or
282 contribution to discussion within Go theory on the scope of "playing
283 style".

326 % Some journals put the first two words in caps:
327 % \IEEEPARstart{T}{his demo} file is ....
329 % Here we have the typical use of a "T" for an initial drop letter
330 % and "HIS" in caps to complete the first word.
331 \IEEEPARstart{T}{he} field of Computer Go usually focuses on the problem
332 of creating a~program to play the game, finding the best move from a~given
333 board position. We will make use of one method developed in the course
334 of such research and apply it to the analysis of existing game records
335 with the aim of helping humans to play the game better instead.
337 Go is a~two-player full-information board game played
338 on a~square grid (usually $19\times19$ lines) with black and white
339 stones; the goal of the game is to surround the most territory and
340 capture enemy stones. We assume basic familiarity with the game.
342 Many Go players are eager to play using computers (usually over
343 the internet) and review games played by others on computers as well.
344 This means that large amounts of game records are collected and digitally
345 stored, enabling easy processing of such collections. However, so far
346 only little has been done with the available data --- we are aware
347 only of uses for simple win/loss statistics (TODO: KGS Stats, KGS Analytics,
348 Pro Go Rating) and ''next move'' statistics on a~specific position (TODO:
349 Kombilo, Moyo Go Studio).
351 We present a~more in-depth approach --- from all played moves, we devise
352 a~compact evaluation of each player. We then explore correlations between
353 evaluations of various players in light of externally given information.
354 This way, we can discover similarity between moves characteristics of
355 players with the same playing strength, or discuss the meaning of the
356 "playing style" concept on the assumption that similar playing styles
357 should yield similar moves characteristics.
360 \section{Expert-based knowledge}
361 \label{style-vectors}
362 In order to provide a reference frame for our style analysis,
363 we have gathered some expert-based information about various
364 traditionally perceived style aspects.
365 Three high-level Go players (Alexander Dinerstein 3-pro, Motoki Noguchi
366 7-dan and Vit Brunner 4-dan) have judged style of several Go
367 professionals (chosen for both being well-known within the community
368 and having large number of played games in our collection).
370 This expert-based knowledge allows us to predict styles of unknown players based on
371 the similarity of their pattern vectors, as well as discover correlations between
372 styles and proportions of played patterns.
374 Experts were asked to assign each of player's style a number
375 on a scale from 1 to 10. These are interpreted
376 as shown in the table below.
378 \vspace{4mm}
379 \noindent
380 %\begin{table}
381 \begin{center}
382 %\caption{Styles}
383 \begin{tabular}{|c|c|c|}
384 \hline
385 \multicolumn{3}{|c|}{Styles} \\ \hline
386 Style & 1 & 10\\ \hline
387 Territoriality & Moyo & Territorial \\
388 Orthodoxity & Classic & Novel \\
389 Aggressivity & Calm & Figting \\
390 Thickness & Safe & Shinogi \\ \hline
391 \end{tabular}
392 \end{center}
393 %\end{table}
395 Averaging and rescaling the expert based evaluation yields a set of
396 \emph{reference style vectors} $\vec s_r$.
397 %-- each with a \emph{pattern vector} $\vec p_i$ and \emph{style vector} $\vec s_i$.
400 \section{Data Extraction}
401 \label{pattern-vectors}
403 As the input of our method, we assume a~collection of game records\footnote{We
404 use the SGF format (TODO) in our implementation.} organized by player names.
405 We use two collections; the first one is GoGoD Winter 2009 (TODO) containing 42000 (TODO)
406 professional games, dating from the early Go history 1500 years ago to the present.
407 We use this collection for style analysis and detailed correlation analysis
408 of well-known Go professionals.
409 The other source is Go Teaching Ladder reviews (TODO). These include 7600 games
410 of players spanning over all strength levels; we use this collection
411 for finding correlations between moves of players of the same strength rank.
413 In order to generate the required compact description of most played moves,
414 for each player, we extract a~generic description from each move
415 played by the player, then take the most occuring $n$ patterns across all players%
416 \footnote{We use $n=500$ in our analysis.} and assign each player a~{\em pattern vector}
417 $\vec d$ where each dimension corresponds to the number of occurences of
418 one given pattern normalized to range $[0,1]$.
420 \subsection{Pattern Features}
422 Of course a big question is how to compose the pattern descriptions.
423 There are some tradeoffs in play - overly general descriptions carry too few
424 information to discern various player attributes; too specific descriptions
425 gather too few specimen over the games and the differences in vectors are
426 not statistically significant.
428 We have chosen an intuitive and simple approach inspired by pattern features
429 used when computing ELO ratings for candidate patterns in Computer Go play.
430 \cite{ELO} Each pattern is combination of several {\em pattern features}
431 matched at the position of the played move. We use these features:
433 \begin{itemize}
434 \item TODO
435 \end{itemize}
437 \subsection{Implementation}
439 We have implemented the data extraction by making use of the pattern
440 features matching implementation within the Pachi go-playing program
441 (TODO). We extract information on players by converting the SGF game
442 records to GTP (TODO) stream that feeds Pachi's {\tt patternscan}
443 engine which outputs a~single patternspec per move. We can then gather
444 all encountered patternspecs belonging to a~given player and summarize
445 them; the $\vec p$ vector then consists of normalized counts of
446 the given $n$ most frequent patternspecs.
449 \section{Data Mining}
450 To assess the properties of gathered \emph{pattern vectors} and their influence on playing styles,
451 we have analysed the data by a~few basic data minining techniques.
453 TODO PCA: We use it either on it own, or as a~pre-processing making data suitable for other methods.
455 TODO rozdelit na algo/results??
457 \subsection{Principal Component Analysis}
458 Principal Component Analysis \emph{PCA} \cite{Jolliffe1986} is a~method we use to reduce the dimensions of
459 \emph{pattern vectors} while preserving as much information as possible.
461 Shortly, PCA is an eigenvalue decomposition of a~covariance matrix of centered \emph{pattern vectors}.
462 It can be thought of as a~mapping $o$ from $n$-dimensional vector space to a~reduced $m$-dimensional vector space.
463 The base of this reduced vector space comprises $m$ eigenvectors of original vectors' covariance matrix.
464 We choose them to be the eigenvectors with biggest eigenvalues.
465 Ordered by decreasing eigenvalues, the eigenvectors form rows of the transformation matrix $W$.
467 Finally, we represent reduced \emph{pattern vectors} as a vector of coeficients of this eigenvector-base.
468 For each original \emph{pattern vector} $\vec p_i$, we obtain its new representation $\vec r_i$ as shown
469 in the following equation:
470 \begin{equation}
471 \vec r_i = W * \vec p_i
472 \end{equation}
474 The whole process is described in the Algorithm \ref{alg:pca}.
476 \begin{algorithm}
477 \caption{PCA -- Principal Component analysis}
478 \begin{algorithmic}[1]
479 \label{alg:pca}

483 \STATE $\vec p_r \leftarrow \vec p_r - \vec \mu$

499 \subsection{k-nearest Neighbors Classifier}
500 K-nearest neigbors is an essential classification technique.
501 We use it to approximate player's \emph{style vector} $\vec S$, assuming that his \emph{pattern vector} $\vec P$ is known.
502 To achieve this, we utilize \emph{reference style vectors} (see section \ref{style-vectors}).
504 The idea is based on a assumption that similarities in players' \emph{pattern vectors}
505 correlate with similarities in players' \emph{style vectors}. We try to approximate $\vec S$
506 as a weighted average of \emph{style vectors}
507 $\vec s_i$ of $k$ players with \emph{pattern vectors} $\vec p_i$ closest to $\vec P$.
508 This is illustrated in the Algorithm \ref{alg:knn}.
509 Note that the weight is a function of distance and it is not explicitly defined in Algorithm \ref{alg:knn}.
510 During our research, exponentialy decreasing weight has proven to be sufficient.
512 \begin{algorithm}
513 \caption{k-Nearest Neighbors}

554 % of issues like this, it may be the safest practice to put all your

557 % Reminder: the "draftcls" or "draftclsnofoot", not "draft", class
558 % option should be used if it is desired that the figures are to be

632 \section{Conclusion}
633 The conclusion goes here.
634 We have shown brm and proposed brm.
636 Since we are not aware of any previous research on this topic and we
637 are limited by space and time constraints, plenty of research remains
638 to be done. There is plenty of room for further research in all parts
639 of our analysis --- different methods of generating the $\vec d$ vectors
640 can be explored; other data mining methods could be tried.
641 It can be argued that many players adjust their style by game conditions
642 (Go development era, handicap, komi and color, time limits, opponent)
643 or styles might express differently in various game stages.
644 Finally, more professional players could be consulted on the findings
645 and for style scales calibration.
