화자간 변별력 최대화를 위한 혼합 모델 방식과 심볼 확률 가중함수에 관한 연구

진세훈,강철호,Chin Se-Hoon,Kang Chul-Ho 한국음향학회 2005 韓國音響學會誌 Vol.24 No.7

최근 대부분의 화자확인 시스템은 패턴 인식 접근방식에 기인하고 있다. 패턴 분류기의 성능은 화자의 특징 파라미터를 어떻게 분류하는가 하는 데에 기인한다. 그 특징 파라미터를 잘 분류하기 위해서는, 화자간 변이를 최대화하고 특징 파라미터 간 거리를 효과적으로 측정하는 것이 매우 중요하다. 따라서, 본 논문에서는 개인 모델과 월드 모델을 동시에 배치함으로써 화자간 변이를 최대화 할 수 있는 개선된 혼합 모델 구조를 제안한다. 결정 과정 시 제안한 혼합 모델 방식을 사용함으로써 화자간 변별력을 최대화 할 수 있었다. 또한, 입력데이터에 대한 개인 모델과 월드 모델의 거리비율에 따라 심볼 확률 값을 가중하여 벡터 양자화 에러를 줄이는 가중치 함수를 제안 한다. 실험 결과, 이두 가지 방법을 취함으로써 DCF (Detection Cost Function)를 $2.37\%$에서 $1.16\%$로 낮출 수 있었다. Recently, most of the speaker verification systems are based on the pattern recognition approach method. And performance of the pattern-classifier depends on how to classify a variety of speakers' feature parameters. In order to classify feature parameters efficiently and effectively, it is of great importance to enlarge variations between speakers and effectively measure distances between feature parameters. Therefore, this paper would suggest the positively mixed model scheme that can enlarge inter-speaker variation by searching the individual model with world model at the same time. During decision procedure, we can maximize inter-speaker variation by using the proposed mixed model scheme. We also make use of a symbol probability weighting function in this system so as to reduce vector quantization errors by measuring symbol probability derived from the distance rate of between the world codebook and individual codebook. As the result of our experiment using this method, we could halve the Detection Cost Function (DCF) of the system from $2.37\%\;to\;1.16\%$.

화자 확인 시스템을 위한 적응적 모델 갱신과 사전 문턱치 결정에 관한 연구

진세훈,이재희,강철호 한국음향학회 2000 韓國音響學會誌 Vol.19 No.5

화자 확인시스템에서 화자의 장기간 음성 변동에 대처하기 위해서는 작은 양의 데이터로써 화자 확인을 위한 HMM(hidden Markov model) 파라미터 갱신과 사전 문턱치 결정이 중요한 요소이다. 본 연구에서는 화자내 변이(mea-speaker variation)에 적응하는 모델 갱신방법과 이에 따른 문턱치 적응에 관한 방법을 제안한다. 제안하는 방법은 분기간 화자내 변이로 발생할 수 있는 오인식율을 Baum-Welch re-estimation을 통해 현재 화자 모델 파라미터에 새로운 음성 데이터를 적응시킴으로써 감소시킨다. 본 논문에서 제안하는 사전 문턱치 결정 방법은 기존의 월드 모델(world model) 방법과 군중 모델(cohort model) 방법의 하이브리드 형태로써 실험적으로 결정된다. 실험에 의해 모델 갱신을 하지 않은 경우보다 제안하는 모델 갱신방법의 화자 인식율이 우수함을 확인하였다. 또한, 사후 문턱치 결정에 의한 인식율과 제안한 사전 문턱치 결정에 의한 인식율의 차이가 근소함을 확인하였다. In speaker verification system the HMM(hidden Markov model) parameter updating using small amount of data and the priori threshold decision are crucial factor for dealing with long-term variability in people voices. In the paper we present the speaker model updating technique which can be adaptable to the session-to-intra speaker variability and the priori threshold determining technique. The proposed technique decreases verification error rates which the session-to-session intra-speaker variability can bring by adapting new speech data to speaker model parameter through Baum Welch re-estimation. And in this study the proposed priori threshold determining technique is decided by a hybrid score measurement which combines the world model based technique and the cohen model based technique together. The results show that the proposed technique can lead a better performance and the difference of performance is small between the posteriori threshold decision based approach and the proposed priori threshold decision based approach.

In general social opinions of developed cultural state, tattoos induced psychological and social problems. Since Hellenic times, the removal of unwanted tattoos has been a challenge: for example, salabrasion, dermabrasion, LASER surgery, skin graft and cryosugery, etc. But the availability of manay methods for the removal of tattoos appears to indicate that there is no one absolute method. So we studied macroscopical color changes and microscopical histological changes in tattooed rabbits and rats, and overtattooed rabbits and rats. The results were as following: 1. Inflammatory reactions was nearly almost disapperared within 3 weeks. 2. The major fade―out of tattooed color was occurred from post―tattooing 5 days to 3 weeks. 3. Dye particle was located mainly in upper & mid dermis and it was not relafted with tattooing depth. 4. Masking effect of black colored tattoos was definitely improved in the overtattooing group. But complete masking was impossible.

안면부교상(Human Bites)의 임상적 고찰

陳世勳,張忠鉉,李斗炯 大韓成形外科學會 1987 Archives of Plastic Surgery Vol.14 No.4

" …of all bites that of the human animal is the worst." Human bites of the face, although infrequent, are emergency situations, and sometimes the plastic & reconstructive surgeon may have to treat. The protruding structures of the face, for example, ear, nose, and lip, were more frequently involved site and their structures are difficult regions in reconstructive surgery. Eventually, aesthetical & functional deformity remained. This series of human bite of the facial regions comprised 74 ca ses treated from 1st Jan. 1974 to 30th June. 1985, in our department of Plastic & Reconstructive Surgery. We have taken as our standard the definition of a human bite proposed by Patons. The result obtained were as follows: 1. The 15 to 20 years of age is the group of peak incidence and the male to female ratio is 60:14 2.The most frequent involved site is ear(31/74) 3.In type of wound, class Ⅰ type is the most frequent(43/73) 4.The most frequent mode of injury is conflict(38/74) 5.Human bites occurred usually in drunken state by the unfamilial male 6.Incidence of infection was 4% 7.Aesthetical & functional reconstruction of the human bite injury was very difficult problems.

확대머리 철근과 갈고리 철근을 이용한 단차가 있는 휨부재의 겹침이음상세

이규선,진세훈,김승훈 한국구조물진단유지관리공학회 2016 한국구조물진단유지관리공학회 논문집 Vol.20 No.4

This paper focuses on the experimental study for investigating the performance for lap splice of hooked or headed reinforcement in beam with different depths. In the experiment, seven specimens, with its variables as the lap length of headed or hooked bar, the existence of stirrups, etc., was manufactured. Bending test was conducted. Lap strengths by test were compared with the theoretical model based on KCI2012. The result showed that the cracks at failure mode occurred along the axial direction to a headed bar. The initial stiffness and the stiffness after initial crack were similar for all specimens. For HS series specimens without stirrups, a 25% increase in lap length was increased 11.8~18.1% maximum strengths. For HH series specimens without stirrups, a increase in lap length did not affect the maximum strengths because of the pryout failure of headed bar. For HS series specimens, the theoretical lap strengths based on KCI2012 considering the B grade lap and the reduction factor for stirrup were evaluated. They are smaller than the test strengths and can ensure the safety in terms of strength capacity. For HH series specimens, the stirrups in the lap zone are needed to prevent the pryout behaviour of headed bar.
