### Mean squared displacement

- Loop over all frames (after the first)
    - Check distance between current and previous frame
    - while (x - x_prev > L/2) x-= L  and so on 
- Calculate mean squared displacement
    - Pick a starting time $t_0$
    - Loop over later times, calculate squared displacements
    - Put them in a list as a function of ($t - t_0$)
    - Repeat for later $t_0$. (for better statistics)



$\langle r^2(t)\rangle = \langle\frac{1}{N}\sum_{i=1}^N (\mathbf{r}_i(t + t_0) - \mathbf{r}_i(t_0))^2 \rangle$

Angular brackets denote the average over multiple starting times

box =3
x-old = (0.5, 0.7, 1.0, 1.5, 1.3, 1.9, 2.5, 0.5, 0.7)
x-new = (0.5, 0.7, 1.0, 1.5, 1.3, 1.9, 2.5, 3.5, 3.7)

(x(t_0 + t)-x(t_0))^2

Here are some results of the propensity calculations and the clustering for different packing fractions $\eta$. Histograms are plotted with their associated probability densities (estimated by kernel density estimation).

Note: Normalized histogram with kernel density estimation based on the normalized summation of standard normal distributions around each data point. Set the kde keyword to False to see the counts on the y axis.

We define an order parameter $P_{red}$ after the dimensionality reduction. It corresponds to the probability of a particle belonging to one of the two clusters. The choice of the reduced dimension is arbitrary for the moment.

## $\eta = 0.75$

We choose a time frame and compute the average propensities for that frame. Clustering of the particles are also done in the same frame. Histogram of the propensities for the chosen time frame is also shown below.

## Using local averages

We consider the local averages of BOPs before feeding them into the neural network. We realise that it improves the FVE for small particles and the BIC now suggests that $N_g = 2$ might be a reasonable choice.
