چکیده
あらまし パターン認識の究極の目標は認識率 100%の達成であるが,誤認識が全く起こらない識別器の設計は容易で はない.そこで,本報告では認識誤りを補うために正解クラスに関する情報 (付加情報)をパターンとは別に用意し, パターンと付加情報を識別器に同時に与えることで認識率 100%かつリジェクト率 0%を達成する方式を提案する.そ して,提案する方式で達成可能な認識率やリジェクト率とそれに必要な情報量の関係を求める.実験の結果,印刷さ れたかな・漢字 3036字種ではオープン実験で 4ビット,クローズ実験で 1ビットの情報の付加で認識率 100%かつリ ジェクト率 0%を達成できることが示された.また,認識を全く行わずに文字コードの情報をそのまま使用する場合に 比べると,提案する方式で必要な情報量は約 1/12,QRコードの面積換算では約 1/9である.従って,提案する方式 は従来のパターン認識のみを用いる場合と認識を行わずコードのみの場合を折衷する新しい枠組みといえる. キーワード 識別器,情報量,混同行列,付加情報

A Database for Automatic Persian Speech Emotion Recognition: Collection, Processing and Evaluation
Abstract Recent developments in robotics automation have motivated researchers to improve the efficiency of interactive systems by making a natural man-machine interaction. Since speech is the most popular method of communication, recognizing human emotions from speech signal becomes a challenging research topic known as Speech Emotion Recognition (SER). In this study, we propose a Persian em...
متن کاملMAN-MACHINE INTERACTION SYSTEM FOR SUBJECT INDEPENDENT SIGN LANGUAGE RECOGNITION USING FUZZY HIDDEN MARKOV MODEL
Sign language recognition has spawned more and more interest in human–computer interaction society. The major challenge that SLR recognition faces now is developing methods that will scale well with increasing vocabulary size with a limited set of training data for the signer independent application. The automatic SLR based on hidden Markov models (HMMs) is very sensitive to gesture's shape inf...
متن کاملRecognition with Supplementary Information — How Many Bits Are Lacking for 100 % Recognition ? —
In this paper, we propose a new model in which the classifier receives not only a pattern itself but also supplementary information that assists recognition. This model enables us to achieve a 100% recognition rate with a 0% rejection rate with certain bits of supplementary information required. For printed characters, experiments show that 4 bits of supplementary information were required in t...
متن کاملMachine learning based Visual Evoked Potential (VEP) Signals Recognition
Introduction: Visual evoked potentials contain certain diagnostic information which have proved to be of importance in the visual systems functional integrity. Due to substantial decrease of amplitude in extra macular stimulation in commonly used pattern VEPs, differentiating normal and abnormal signals can prove to be quite an obstacle. Due to developments of use of machine l...
متن کاملClassification of emotional speech using spectral pattern features
Speech Emotion Recognition (SER) is a new and challenging research area with a wide range of applications in man-machine interactions. The aim of a SER system is to recognize human emotion by analyzing the acoustics of speech sound. In this study, we propose Spectral Pattern features (SPs) and Harmonic Energy features (HEs) for emotion recognition. These features extracted from the spectrogram ...
