The spline probability hypothesis density filter

The SMC-PHDfilter technique provides only weighted samples at discrete points inthe state space instead of a continuous estimate of the probabilitydensity function of the system state and thus suffers from thewell-known degeneracy problem.

Now, let's first start by verifying that f(x) is a valid probability density function.

The resultingalgorithm can handle linear, non-linear, Gaussian, and non-Gaussianmodels and the S-PHD filter can also provide continuous estimates of theprobability density function of the system state.

For example, when both parameters are integer with random variables the result is the binomial Probability function.

The FISST Bayes multi-object recursion is generally intractable. In2000 Mahler proposed to approximate the multi-object Bayes recursion bypropagating the Probability Hypothesis Density (PHD) of the posteriormulti-object state ,,,.This strategy is reminiscent of the constant gain Kalman filter thatpropagates the mean of the posterior single-object state. The PHDfilter is an innovative and elegant engineering approximation thatcaptivated many researchers in multi-target tracking. More importantly,it provides an important step towards the practical application ofFISST. The PHD recursion still involves multipleintegrals with no closed forms in general.

Two distinct PHDfilter implementations are available in the literature: the SequentialMonte Carlo Probability Hypothesis Density (SMC-PHD) and the GaussianMixture Probability Hypothesis Density (GM-PHD) filters.

Notice that the probability P is the area under the density function curve, while numerically equal to the height of cdf curve at point x.

The probability density function ("p.d.f

A continuous random variable takes on an uncountably infinite number of possible values. For a discrete random variable X that takes on a finite or countably infinite number of possible values, we determined P(X = x) for all of the possible values of X, and called it the probability mass function ("p.m.f."). For continuous random variables, as we shall soon see, the probability that X takes on any particular value x is 0. That is, finding P(X = x) for a continuous random variable X is not going to work. Instead, we'll need to find the probability that X falls in some interval (a, b), that is, we'll need to find P(a X b). We'll do that using a probability density function ("p.d.f."). We'll first motivate a p.d.f. with an example, and then we'll formally define it.

Kappa Probability Density Function

Solution. In reality, I'm not particularly interested in using this example just so that you'll know whether or not you've been ripped off the next time you order a hamburger! Instead, I'm interested in using the example to illustrate the idea behind a probability density function.

Compute the kappa probability density function ..

Such a curve is denoted f(x) and is called a (continuous) probability density function.

The probability density function is then found by using the following relation (given on page 46 of Johnson, Kotz, and Balakrishnan): where is the cumulative distribution function and Syntax:

denotes the probability hypothesis density ..

Now, you might recall that a density histogram is defined so that the area of each rectangle equals the relative frequency of the corresponding class, and the area of the entire histogram equals 1. That suggests then that finding the probability that a continuous random variable X falls in some interval of values involves finding the area under the curve f(x) sandwiched by the endpoints of the interval. In the case of this example, the probability that a randomly selected hamburger weighs between 0.20 and 0.30 pounds is then this area:
