Movement Discovery and Anomalous Activity Explanation Raffay Hamid, Amos Johnson, Samir Batta, Aaron Bobick, Charles Isbell, Graham Coleman

Slide 2

Activity Discovery and Anomalous Activity Explanation

Slide 3

Activity Discovery and Anomalous Activity Explanation Anomaly - “ deviation ” from the “ normal ” or “ general ”

Slide 4

Activity Discovery and Anomalous Activity Explanation Anomaly - “ deviation ” from the “ basic ” or “ standard ” Key Questions: ‘ representation ’ of exercises ‘ customary ’ exercises ‘ diverse ’ from consistent ‘ clarify ’ an abnormality

Slide 5

Activity Discovery and Anomalous Activity Explanation Anomaly - “ deviation ” from the “ basic ” or “ standard ” Key Questions: ‘ representation ’ of exercises ‘ general ’ exercises ‘ distinctive ’ from normal ‘ clarify ’ an inconsistency

Slide 6

Activity Representation Previous representations include: Stochastic Context Free Grammars Expectation Grammars …..

Slide 7

Activity Representation Previous representations include: Stochastic Context Free Grammars Expectation Grammars ….. Oblige approximately from the earlier data about movement structure

Slide 8

Activity Representation Two bits of data: substance structure Drawing from Natural Language Processing – regarding reports as packs of words Treat Activities as sacks of occasion n-grams Extraction of worldwide auxiliary data utilizing nearby occasion insights

Slide 9

Activity Representation Two bits of data: substance structure Drawing from Natural Language Processing – regarding archives as packs of words – catches substance well Treat Activities as packs of occasion n-grams Extraction of worldwide basic data utilizing neighborhood occasion measurements

Slide 10

Activity Representation Two bits of data: substance structure Drawing from Natural Language Processing – regarding records as sacks of words – catches substance well Treat Activities as packs of occasion n-grams – catches action structure Extraction of worldwide basic data utilizing neighborhood occasion measurements

Slide 11

Activity Representation Two bits of data: substance structure Drawing from Natural Language Processing – regarding archives as sacks of words – catches substance well Treat Activities as packs of occasion n-grams – catches action structure Extraction of worldwide basic data utilizing neighborhood occasion insights

Slide 14

Activity Discovery and Anomalous Activity Explanation Anomaly - “ deviation ” from the “ basic ” or “ standard ” Key Questions: ‘ representation ’ of exercises ‘ customary ’ exercises ‘ diverse ’ from consistent ‘ clarify ’ an oddity

Slide 15

Activity Discovery and Anomalous Activity Explanation Anomaly - “ deviation ” from the “ basic ” or “ normal ” Key Questions: ‘ representation ’ of exercises ‘ general ’ exercises ‘ distinctive ’ from normal ‘ clarify ’ a peculiarity - Occur much of the time - Are like one another.:

Slide 16

Activity Discovery and Anomalous Activity Explanation Anomaly - “ deviation ” from the “ basic ” or “ consistent ” Key Questions: ‘ representation ’ of exercises ‘ normal ’ exercises ‘ distinctive ’ from normal ‘ clarify ’ an oddity - Activity comparability - Activity disclosure

Slide 17

Activity Similarity Two sorts of contrasts center basic contrasts (csd) occasion recurrence contrasts (efd) Sim (A,B) = w 1* CSD(A,B) + w 2* EFD(A,B) Properties: Identity Commutative Positive semi-unequivocal

Slide 18

Activity Similarity Two sorts of contrasts center basic contrasts (csd) occasion recurrence contrasts (efd) Properties: Identity Commutative Positive semi-unmistakable

Slide 19

Activity Similarity Two sorts of contrasts center basic contrasts (csd) occasion recurrence contrasts (efd) Properties: Identity Commutative Positive semi-clear

Slide 20

Activity Discovery and Anomalous Activity Explanation Anomaly - “ deviation ” from the “ basic ” or “ standard ” Key Questions: ‘ representation ’ of exercises ‘ customary ’ exercises ‘ distinctive ’ from general ‘ clarify ’ an irregularity Activity closeness - Activity revelation

Slide 21

Activity Sub-Class Discovery Recall: standard exercises happen often and are like one another Activity Sub-Class Discovery - a Graphic Theoretic issue of discovering maximal clubs in edge-weighted diagrams Maximal Cliques: general similitude between inner circle hubs more noteworthy than some quality, expansion of whatever other hub would decrease the general coterie likeness

Slide 22

Activity Sub-Class Discovery Recall: general exercises happen every now and again and are like one another Activity Sub-Class Discovery - a Graphic Theoretic issue of discovering maximal factions in edge-weighted charts Maximal Cliques: general similitude between coterie hubs more noteworthy than some worth, expansion of some other hub would lessen the general club closeness

Slide 23

Activity Sub-Class Discovery Recall: general exercises happen oftentimes and are like one another Activity Sub-Class Discovery - a Graphic Theoretic issue of discovering maximal coteries in edge-weighted charts Maximal Cliques : general comparability between coterie hubs more prominent than some worth, expansion of some other hub would diminish the general faction similitude

Slide 24

Activity Sub-Class Discovery Sequentially find maximal clubs in edge weighted chart of exercises Activities sufficiently diverse from all the customary exercises are oddities

Slide 25

Activity Sub-Class Discovery Sequentially find maximal clubs in edge weighted chart of exercises Activities sufficiently diverse from all the consistent exercises are inconsistencies

Slide 26

Activity Sub-Class Discovery Sequentially find maximal inner circles in edge weighted chart of exercises Activities sufficiently distinctive from all the general exercises are oddities

Slide 27

Activity Discovery and Anomalous Activity Explanation Anomaly - “ deviation ” from the “ basic ” or “ standard ” Key Questions: ‘ representation ’ of exercises ‘ consistent ’ exercises ‘ distinctive ’ from consistent ‘ clarify ’ an oddity

Slide 28

Activity Discovery and Anomalous Activity Explanation Anomaly - “ deviation ” from the “ basic ” or “ customary ” Key Questions: ‘ representation ’ of exercises ‘ normal ’ exercises ‘ distinctive ’ from normal ‘ clarify ’ an abnormality Activity characterization - Anomaly location

Slide 29

Activity Classification Compute weighted similitude between another action T and past class individuals as: Select enrollment sub-class as:

Slide 30

Activity Classification Compute weighted closeness between another action T and past class individuals as: Select participation sub-class as:

Slide 31

Activity Discovery and Anomalous Activity Explanation Anomaly - “ deviation ” from the “ basic ” or “ normal ” Key Questions: ‘ representation ’ of exercises ‘ customary ’ exercises ‘ diverse ’ from consistent ‘ clarify ’ an oddity Activity arrangement - Anomaly identification

Slide 32

Anomaly Detection Define capacity Learn the recognition edge from preparing information

Slide 33

Anomaly Detection Define capacity Represents the inside of Class distinction of the test action w.r.t. past class individuals Pick a specific edge to distinguish irregularities

Slide 34

Anomaly Detection Define capacity Represents the inside of Class distinction of the test action w.r.t. past class individuals Pick (take in) a specific limit to distinguish peculiarities

Slide 35

Activity Discovery and Anomalous Activity Explanation Anomaly - “ deviation ” from the “ normal ” or “ customary ” Key Questions: ‘ representation ’ of exercises ‘ standard ’ exercises ‘ diverse ’ from general ‘ clarify ’ an irregularity

Slide 36

Anomaly Explanation Explanatory components: Consistent Frequent Explanation in light of elements that were: Deficient from an abnormality however were every now and again and reliably exhibit in consistent individuals Extraneous in an oddity yet reliably truant from the customary individuals

Slide 37

Anomaly Explanation Explanatory elements: Consistent Frequent Explanation in view of elements that were: Deficient from an oddity yet were much of the time and reliably display in normal individuals Extraneous in an oddity yet reliably truant from the customary individuals

Slide 38

Anomaly Explanation Explanatory elements: Consistent Frequent Explanation taking into account highlights that were: Deficient from an inconsistency yet were as often as possible and reliably show in customary individuals Extraneous in an oddity yet reliably missing from the customary individuals
