The Why’s of Machine Learning

6. Copyright © 2016 Splunk Inc.
Historical Data Real-time Data Statistical Models
DB, HDFS, NoSQL, Splunk, etc Machine Learning
T – a few days T + a few days
Why is this so challenging using traditional methods?
• DATA IS STILL IN MOTION, still in a BUSINESS PROCESS.
• Enrich real-time MACHINE DATA with structured HISTORICAL DATA
• Make decisions IN REAL TIME using ALL THE DATA

What is Machine Learning?

8. 8
Machine Learning 101: What is it?
• Machine Learning is a process for generalizing from examples
– Examples = example or “training” data
– Generalizing = building “statistical models” to capture correlations
– Process = never quite done, we keep validating & refitting models for
increasing accuracy
• Simple Machine Learning workflow:
– Explore data
– FIT models based on data
– APPLY models in production
– Keep validating models
“All models are wrong, but some are useful.”

9. 9
Three Types of Machine Learning
1. Supervised Learning: generalizing from labeled data
OR?
Gather data:
• Dimensions
• Stem Length
• Color
• Etc.

10. 10
Three Types of Machine Learning
2. Unsupervised Learning: generalizing from unlabeled data
Will my home sell?
Gather data:
• Square feet
• Levels
• Parks nearby
• Schools
• Zipcode
• Etc.

Machine Learning
Use Cases

13. 13
IT Ops: Predictive Maintenance
1. Get resource usage data (CPU, latency, outage reports)
2. Explore data, and fit predictive models on past / real-time data
3. Apply & validate models until predictions are accurate
4. Forecast resource saturation, demand & usage
5. Surface incidents to IT Ops, who INVESTIGATES & ACTS
Problem: Network outages and truck rolls cause big time & money expense
Solution: Build predictive model to forecast outage scenarios, act pre-emptively & learn

14. 14
Security: Find Insider Threats
Problem: Security breaches cause big time & money expense
Solution: Build predictive model to forecast threat scenarios, act pre-emptively & learn
1. Get security data (data transfers, authentication, incidents)
2. Explore data, and fit predictive models on past / real-time data
3. Apply & validate models until predictions are accurate
4. Forecast abnormal behavior, risk scores & notable events
5. Surface incidents to Security Ops, who INVESTIGATES & ACTS

15. 15
Business Analytics: Predict Customer Churn
Problem: Customer churn causes big time & money expense
Solution: Build predictive model to forecast possible churn, act pre-emptively & learn
1. Get customer data (set-top boxes, web logs, transaction history)
2. Explore data, and fit predictive models on past / real-time data
3. Apply & validate models until predictions are accurate
4. Identify customers likely to churn
5. Surface incidents to Business Ops, who INVESTIGATES & ACTS

16. 16
Summary: The Machine Learning Process
Problem: <Stuff in the world> causes big time & money expense
Solution: Build predictive model to forecast <possible incidents>, act pre-emptively & learn
1. Get all relevant data to problem
2. Explore data, and fit predictive models on past / real-time data
3. Apply & validate models until predictions are accurate
4. Forecast KPIs & metrics associated to use case
5. Surface incidents to X Ops, who INVESTIGATES & ACTS

2. Explore Data, Build Searches & Dashboards
• Start with the Exploratory Data Analysis phase
– “80% of data science is sourcing, cleaning, and preparing the data”
• For each data source, build “data diagnostic” dashboard
– What’s interesting? Throw up some basic charts.
– What’s relevant for this use case?
– Any anomalies? Are thresholds useful?
• Mix data streams & compute aggregates
– Compute KPIs & statistics w/ stats, eventstats, etc.
– Enrich data streams with useful structured data
– stats count by X Y – where X,Y from different sources

20. 20
3. Get the ML Toolkit & Showcase App
• Get the App! https://splunkbase.splunk.com/app/2890
• Leverages Python for Scientific Computing (PSC) add-on:
– Open-source Python data science ecosystem
– NumPy, SciPy, scitkit-learn, pandas, statsmodels
• Showcase use cases: Hard Drive Failure, Server Power consumption,
Server Response Time, Application Usage
• Standard algorithms out of the box:
– Supervised: Logistic Regression, SVM, Linear Regression, Random Forest
– Unsupervised: KMeans, DBSCAN, Spectral Clustering
• Implement one of 300+ algorithms by editing Python scripts

21. 21
4. Fit, Apply & Validate Models
• Machine Learning SPL – New grammar for doing ML in Splunk
• fit – fit models based on training data
– [training data] | fit LinearRegression costly_KPI
from feature1 feature2 feature3 into my_model
• apply – apply models on testing and production data
– [testing/production data] | apply my_model
• Validate Your Model (The Hard Part)
– Why hard? Because statistics is hard! Also: model error ≠ real world risk.
– Analyze residuals, mean-square error, goodness of fit, cross-validate, etc.
– Take Splunk’s Analytics & Data Science Education course

22. 22
5. Operationalize Your Models
• Remember the ML Process:
1. Get data
2. Explore data & fit models
3. Apply & validate models
4. Forecast KPIs
5. Surface incidents to Ops team
• Then operationalize: feed back Ops analysis to data inputs, repeat
• Be patient, this takes time, but lots of value will come out.
