ill-posed

In a series of papers several ill-posed problems are investigated.

Such ill-posed problems are not usually satisfactory for physical applications.

In all ill-posed problems, only a reasonable approximation to the solution can be found.

He also wrote on numerical analysis and ill-posed problems.

This was first introduced by Tikhonov to solve ill-posed problems.

He demonstrated that retrieval of vegetation parameters is an ill-posed problem.

However, this is known as an ill-posed problem.

In this sense the inverse problem of inferring from measured is ill-posed.

Strictly speaking, this question is ill-posed, since there are always numerous different ways to continue a given exact sequence to the right.

This method has been tested on ill-posed geophysical inversion problems and works well.

Note that for an ill-posed problem one must necessarily introduce some additional assumptions in order to get a unique solution.

The mathematical problem represented is typically ill-posed because it has an infinitude of solutions.

For ill-posed problems, the iterative method may be purposefully stopped before convergence.

It is also used in image processing, since many image problems, such as deconvolution, are ill-posed.

In this sense, shrinkage is used to regularize ill-posed inference problems.

As if in answer to my ill-posed question, there came a shout-distant, yet distinct-a cry of challenge.

Focus recovery from a defocused image is an ill-posed problem since it loses the component of high frequency.

However, it is important to note that the very question is ill-posed, since different topological features can be found in the same data set.

He made important contributions to topology, functional analysis, mathematical physics, and certain classes of ill-posed problems.

It is a regularization method for obtaining meaningful solutions to ill-posed inverse problems.

Also, in many applications, the dimensionality exceeds the number of available spectra leading to an ill-posed classification situation.

All these problems are ill-posed.

A regularization approach for constructing an approximate solution to the ill-posed integral equation is proposed.

Thus, the mental causation question is ill-posed.
