M. Sugiyama. An Efficient Similar Segment Search Algorithm in
Multiple Time Series. Trans. of IPSJ, 49(1):487-496, Jan 2008. |
| This paper formulates a similar segment search problem in multiple time series of the
feature vectors and proves that skip region for rejection/detection is equal to a hyper
diamond shape (l1 ball) in the time index space and the upper bound of the ball radius
is derived. In order to solve the search problem, this paper proposes a new algorithm:
RDDS (Recursive Diamond Division Search), and implemented and evaluated RDDS in
two and three time series problem. The experiment results show that RDDS runs about
163 times faster than repeated AS algorithm in two time series and 4.910 × 106 times
faster than the exhaustive search algorithm in three time series. |

| In this paper, we proposed a robot self position identification method by active sound
localization. This method can be used for autonomous security robots working in
room environments. By localizing three or four speakers as sound beacons positioned
on known locations, the robot can identify its self position. |

| This paper presents the research on stability for biped walking-chair robot with humanin-
the-loop. The inherent properties of the biped system which is developed for the
disable people to replace traditional wheelchairs are analyzed. Control of the robot for
the gait and navigation is introduced. Posture stability computation method based on
ZMP (zero moment point) theory is discussed. |

| In this paper, we described a robotic spatial sound localization system using four
microphones arranged on the surface of a spherical robot head. To integrate spatial
cues of different microphone pairs, a mapping method from the correlation between
different microphone pairs to a 2-D map corresponding to azimuth and elevation of
sound sources was proposed. |

Speech Playback Method. In Proc. of SPECOM2007, pages 215-221,
Oct 2007. |
| Audio-visual equipment has improved considerably over recent years, with devices currently
capable of storing considerable amounts of multimedia data. While the storage
of data is performed automatically by machines, the management is performed by humans,
forming a bottle-neck and a sector of multimedia data processing that needs
improvement. This paper focuses on the audio section of multimedia data and assesses
a time-compressed speech playback method. The proposed method detects the voice
section of the data and deletes continuous sections using a feature parameter Block
Cepstrum Flux (BCF) and voice/non-voice classification method. By removing nonvoice
sections from audio data, greater compression of data with a more slowly voice
can be obtained compared to that possible with a constant compression rate. Experimental
results from compressed-sound listening tests showed that the proposed method
had several advantages when compared to methods employing a constant compression
rate. |

| This paper describes a search problem of similar segments in three time-series and
shows the effectiveness of RDDS (Recursive Diamond Division Search) for the similar
segment search problem. The experimental results show that RDDS gives completely
same search results as the Exhaustive Search and RDDS runs about 106 times faster
than the Exhaustive Search. |

| This paper describes a new implementation of RDDS-n to solve a similar segment search
in an arbitrary number of time-series. This new implementation can process arbitrary
time-series, so each implementation considering the number of time-series does not
need. This new proposed implementation achieves the same level of processing time
against RDDS-3 which depends on number of time-series. The new implementation are
evaluated on 3, 4, 5 time-series. |
