galton.uchicago.eduConversely, any linear function solves (4). To determine the coefficients B,C, use the boundary conditions: these imply C =0 and B =1=A. This proves Proposition 1. Px fST =Ag x=A. Remark 1. We will see later in the course that first-passage problems for Markov chains and continuous-time Markov processes are, in much the same way, related to ...

A discrete-time stochastic process {X n: n ≥ 0} on a countable set S is a collection of S-valued random variables defined on a probability space (Ω,F,P).The Pis a probability measure on a family of events F (a σ-field) in an event-space Ω.1 The set Sis the state space of the …

Probability, Random Processes, and Ergodic Properties
ee.stanford.educontinuous time models via discrete time models by letting the outputs be pieces of waveforms. Thus, in a sense, discrete time systems can be used as a building block for continuous time systems. Another topic clearly absent is that of spectral theory …

cims.nyu.eduSample spaces may be discrete or continuous. Examples of discrete sample spaces include the possible outcomes of a coin toss, the score of a basketball game, the number of people that show up at a party, etc. Continuous sample spaces are usually intervals of R or Rn used to model time, position, temperature, etc.
Partially Observable Markov Decision Processes (POMDPs)
www.cs.cmu.edu21 Value Iteration for POMDPs The value function of POMDPs can be represented as max of linear segments This is piecewise-linear-convex (let’s think about why) Convexity State is known at edges of belief space Can always do better with more knowledge of state Linear segments Horizon 1 segments are linear (belief times reward) Horizon n segments are linear …
