4. China moves aggressively into AI &
Blockchain…US fast-follower, regulators
will be forced to keep at bay

“China is really bullish on
blockchain, the technology that
verifies bitcoin transactions.”
-- Charlie Wood Oct 28, 2019, 7:04 AM (Business Insider)
9. SEC issues “No-
Action” Letter
Watch Paxos for T+2 to T+0,
settlement success!
Blockchain replaces complex
“paper” processes, saves trees!
Watch for Frank Yiannas (the
“Mango-Man”) at FDA (prior
Walmart)

• Based on first principles, only black/white stones as inputs
• No human data
• 3-days AlphaGo Zero surpasses AlphaGo level

42. Motivation
• Cell phone location proxies demand
• Buying shoes, which store?
Under Armour (UA) or Nike (NKE)
• Linkages to prices
Q: Does geo-location activity predict spreads
between UA and NKE prices?
Answer: Yes! But with many caveats…
11/22/2019 Prof Jim Kyung-Soo Liew 42
43. Geo-location Data (43 billion, Jan-July ‘18)
www.Fysical.com
11/22/2019 Prof Jim Kyung-Soo Liew 43
53. Conclusions
• Geo-location statistically significant (daily)
• Bests usual suspects: prior prices, volume, tweets, etc.
• Consistently in top features across AI/ML algos
• Weakness lack of long history
• Promising results -- hints at possible daily over-
reaction behavior

55. Big Data Definitions:
Merriam-Webster:
An accumulation of data that is too large and
complex for processing by traditional database
management tools
Wikipedia:
Big data is a term for data sets that are so
large or complex that traditional software is
inadequate to deal with them

56. Big Data’s 3 V’s
• Volume – How much data is created?
“The data volumes are exploding, more data has been created in the past
two years than in the entire previous history of the human race.” -Forbes
• Velocity – How fast (velocity) is data created?
http://www.internetlivestats.com/ (per second)
• Variety – What type of data is created?
i-Phone – voice, SMS, email, photos, videos, emoji
chats, geo-location lat/long, networks, etc.

59. Reality of Big Data
• Never perfect, and painful to clean up
• Allocate about 70-80% time/effort to munge,
never 100% done!
• Work with Subject Matter Expert (SME) -- great
results!
• Even with non-perfect data, typically discover
very insightful relationships
Best results are intuitive, obvious ex post
