This paper deals with curve fitting by a piecewise cubic polynomial which is continuous with its first derivative. A knot is inserted successively until a certain criterion is satisfied. Then aâ€¦ (More)

A method is described for fitting a piecewise cubic polynomial to a sequence of data by a onepass method. The polynomial pieces are calculated as the data is scanned only once from left to right. Theâ€¦ (More)

An on-line recognition method for hand-written characters utilizing stroke vector sequences and a positional vector sequence has been developed. The number of target characters is about 2000, andâ€¦ (More)

The numerical interpolation of multivariable functions has been solved before by the Monte Carlo method, where data points are assumed to be given on discrete lattice points. When data points areâ€¦ (More)

Numerical evaluation of integrals in two or more dimensions has been developed mainly for simple regions such as cube, sphere, simplex, etc. This paper deals with numerical integration in a closedâ€¦ (More)

The problem of estimating an unknown probability density function from a sequence of samples is well known in pattern classification and many other problems. We approximate the unknown densityâ€¦ (More)
