I remember
this feeling,
it means…Temperature
was 100F+
with high
winds
I remember
Tail #123
reported a
similar issue.
The last time the
pilot reported
this problem…
RESULT: 100% recall 1% false alarms
Up from 66% recall 16% false alarmsData Sources: Structured and unstructured, Maintenance records,
purchase orders, work orders, everything that speaks to these issues

4. Early Warning System
Structured and Unstructured Data
Strategic Early Warning
System – Igor Ansoff
Scan environment to
detect weak signals &
rare events to predict
surprises
Find the unknown enemy to protect The Foundation
Early warning system to score threats from people & groups based
on dynamic incremental machine learning
Incidence Reporting
Metadata + E-mails
Harvested Web Pages
(Terabytes & growing )
Detect weak signals to predict threat

5. Pattern Recognition In Healthcare
Intelligent Platforms for Disease Assessment
Novel Approaches in Functional Echocardiograph,
Partho P. Sengupta, in JACC: Cardiovascular Imaging, 11/2013
Automate Echocardiogram Diagnoses
Heat maps show separation of disease
states. Associations between variables in
restrictive cardiomyopathy (red) separate
from dominant associations in constrictive
pericarditis (green)
State of the art
C-tree 54% using 7
attributes
Best doctor 76%
Saffron 90%
90 metrics, 6 locations, 20 time frames
10,000 attributes/beat*patient
-> 100 million triples / beat*patient

6. Match Made in Heaven
Cognitive Distance  Associative Memories
Universality
• Cognitive Distance is universal
• C. Bennett, IBM, 1997; M Hutter, IDSIA, 2000 AIXI
• Nonparametric, incremental, deterministic weights
Context
• Cognitive Distance depends on context
• AM fabric stores context – complete graph
Compression
• K Complexity measures compressibility
• Associative Memories are perfect compressor

7. Kolmogorov Complexity – Signal vs. Noise
Snake eyes are regular sequence -> regular cause, meaning
probability > 0
for snake eyes!
100X
Place a huge bet on
simple outcomes – fair
dice have no pattern

8. How Do Extract Similarity Automatically?
Cognitive Distance based on Kolmogorov Complexity
Approximating Kolmogorov Complexity K(x) ~ log x/N we get
CD ~ max {log(fx),log(y)}-log(x,y) / ( logN-min{log(x),log(y)}
 the saddle is closer to the cowboy
x=131M
“saddle”
y=87M
“movie”
y=1,890M
xy=73M xy=8M
What is closer to cowboy?
1. saddle or
2. movie

9. Not Always So Easy - Context Resolves Ambiguity
Cognition Is About Context
Cognitive Distance Allows for Condition
CD|c ~ max {log(xc|c),log(yc|c)}-log(xc,yc|c) /
( logN-min{log(xc|c),log(yc|c)} )

10. The Bride: Scaling Associative Memory

11. NoSQL - Associative Memories Are Truly
Asynchronous Computing
Connections and counts
synapses and strengths
Hopfield Network
Ising Model for order  disorder phase transition
e.g. Ferromagnetism
weights are
deterministic 
parameter free

12. Saffron’s Solution - Large Scale Machine Learning on
Sparse Matrices
Why is this so special?
• Non-parametric, non-
linear & instant
incremental learning
• Graph & statistics
• Millions of features
• Saffron stores &
queries billions of triple
counts

Build the Brain
1. Unify structured & un-structured data
2. Extract entities
3. Build semantic graph with counts on edges  stored as triples
Make the Brain Think
• Reason by similarity with
cognitive distance

13. Happy Ending – Offspring of KC & AM
 Discovery – Search
– Entity ranking and semantic context
– Convergence – the distance over time
 Classification
– Predicting risk (bad, good)
– Customer life time value
– Echocardiogram diagnosis
 Clustering
– Evolutionary trees, languages, music
– Novelty detection: spare parts, planes, etc.

14. Convergence: Cognitive Distance over Time

15. Take Away
