If we could know in 2020 what we will know in 2025 (only five
foreseeable years into the future), how would we change our
attitudes, actions, and the way in which we practice law, the
services we offer, the clients we target, and the ways in which we
choose to deliver our services? Indeed - if we could have known a
year ago the events of the first three months in 2020, what might
we have done to prepare? The American writer and humorist, Mark
Twain, advised: "When everybody is out digging for gold, the
business to be in is selling shovels!" So, what foreseeable trend
may represent the figurative "shovel" that every client will need
tomorrow?
By clustering data into homogeneous groups, analysts can accurately
detect anomalies within an image. This research was conducted to
determine the most robust algorithm and settings for clustering
hyperspectral images. Multiple images were analyzed, employing a
variety of clustering algorithms under numerous conditions to
include distance measurements for the algorithms and prior data
reduction techniques. Various clustering algorithms were employed,
including a hierarchical method, ISODATA, K-means, and X-means, and
were used on a simple two dimensional dataset in order to discover
potential problems with the algorithms. Subsequently, the lessons
learned were applied to a subset of a hyperspectral image with
known clustering, and the algorithms were scored on how well they
performed as the number of outliers was increased. The best
algorithm was then used to cluster each of the multiple images
using every variable combination tested, and the clusters were
input into two global anomaly detectors to determine and validate
the most robust algorithm settings.
