摘要:
An authentication system determines if a counterfeit ineligible unit is installed in a main device. When connected with a battery pack, a notebook PC generates and combines a random number and a function determination signal using a signal combining unit and transmits same to the battery pack. A first function calculation unit calculates the function of the random number. The battery pack has a signal separation unit to separate the combined signal into the random number and function determination signal, and a second function calculation unit to calculate the function of the random number for transmitting back to the notebook PC. A comparison unit compares the calculation results by the first and second function calculation units to determine whether the connected battery pack is an authorized one and denies connection if the pack is an unauthorized one.

A method and apparatus for estimating parameters of a new hidden Markov model (HMM) applicable to pattern recognition such as recognition of speech signals which are time series signals, and a method and apparatus for pattern recognition employing this HMM. It is easily applicable to speech and other time series signals. In particular, the pattern recognition degree of a time series observation vector signal y, received from an information source, is calculated by using function values u(y,1), u(y,2), . . . , u(y,M) and occurrence probabilities of signals C.sub.1, C.sub.2, . . . , C.sub.M which are composed of set C, where u(y,m) is the image into which the pair (C.sub.m,Y) is mapped, u(y,m).epsilon.U (U=[a,b], a,b.epsilon.R.sup.1 and 0.ltoreq.a.ltoreq.b) and y.epsilon.R.sup.n (R.sup.n :n-dimensional Euclidean space).

摘要:
An authentication system is provided, which prevents any glitches or accidents caused by a counterfeit ineligible unit being installed in a main device. When connected with a battery pack (an authenticated unit), a notebook PC (an authenticating device) allows a random number and a function determination signal to be generated and then combined by a signal combining unit to be transmitted to the battery pack. Meanwhile, a first function calculation unit calculates the function of the random number. The battery pack allows a signal separation unit to separate the combined signal into the random number and function determination signal, and a second function calculation unit to calculate the function of the random number for transmitting back to the notebook PC. A comparison unit compares the calculation results by the first and second function calculation units to determine whether the connected battery pack is an authorized one. If the pack is an authorized one, a connection determination unit permits the connection. If the pack is an unauthorized one, the connection of the pack is rejected.
摘要:
A codebook for vector quantization is speaker-adapted or a speaker is normalized so that it complies with the codebook using a small number of samples for learning. A deviation vector is set for the centroid of each cluster or an input vector. The deviation vector is set so that a separately defined objective function is maximized if it is defined to be maximized, or minimized if it is defined to be minimized. The maximization or minimization is performed using samples for learning obtained from a speaker who uses the system when the centroid or input vector is moved by an amount corresponding to the deviation vector. By moving the centroid or input vector using the deviation vector, speaker adaptation is performed if the former is moved and speaker normalization is performed if the latter is moved.
