PARRY is if ELIZA had mental states such as fear, anger, and mistrust. Mentions of various things in the user turn increases or decreases each variable

Differential Equations in more than one independent variable:

\begin{equation} f(x_1, \dots, x_{n}) \end{equation}

Partially Observable Markov Decision Process is a with .

Components:

• • states
  • actions (given state)
  • transition function (given state and actions)
  • reward function
• Belief System
  • beliefs
  • observations
  • observation model \(O(o|a,s’)\)

As always we desire to find a \(\pi\) such that we can:

\begin{equation} \underset{\pi \in \Pi}{\text{maximize}}\ \mathbb{E} \qty[ \sum_{t=0}^{\infty} \gamma^{t} R(b_{t}, \pi(b_{t}))] \end{equation}

whereby our \(\pi\) instead of taking in a state for input takes in a belief (over possible states) as input.

One-Liner

An excercize scheme has had some measured effect on theta/alpha ratio and Brain wave frequency on AD patients; prognosis of AD not controlled for.

Novelty

• Leveraged physical training scheme and measured EEG effects by quantifying theta/alpha ratio

Notable Methods

• Used theta/alpha ratio as assay for improvement, and found the exercise scheme did so p<0.05
• Only tested patients with AD w/o a control for stage
