Kimikazu Kato is the Chief Scientist at Silver Egg Technology, which provides recommender system and online advertising services. He has a PhD in computer science and experience in areas like computer graphics and parallel computing. Silver Egg uses a real-time recommender platform called Aigent Suite to consistently target users from initial visits to retention. The system analyzes user behavior data to determine personalized recommendations and ad targeting. While collaborative filtering and matrix factorization are common recommendation algorithms, approaches need adjustments for sales recommendations versus movie ratings. Consulting is also important for tuning algorithm parameters to specific business needs.

Customer experience letter Bank of America thoughtsClient X Client
Bank of America's Chairman's letter to 270000 employees about customer experience got my attention as a customer and a customer experience strategist. Why does the bank suddenly care about customer experience? Will my experience change? Will change be for better? Whom will be affected by change? What are the costs? How will employees think differently? How will customer experience be made visible to employees? Connected to roles? Who is ultimately responsible for BofA's customer experience?

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

• Just showing the result of mathematical

• To extract optimal sales, parameters should be

algorithm to predict user ratings for films, based on previous ratings
— Wikipedia
Netflix provided open data for this competition
Closed in 2009

12. Movie Rating Prediction
Each user gives rating to the movies they saw
movie
user W X Y Z
A 5 4 1 4
B 4
C 2 3
D 1 4 ?
Is it possible to predict the rating of unknown user/movie pair?
Ratings are expressed as a sparse matrix.
A zero value of the matrix doesn’t really mean “zero” but “unknown”
11
13. Probabilistic Matrix Factorization
Regarding ratings are expressed by small number of components
𝐴 𝑈𝑇 𝑉 noise
Approximate only the non-zero elements
12
15. Rating vs Purchase
Movie rating Purchase recommendation
movie item

A 5 4 1 4 A 1 1 1 1
B 4 B 1
C 2 3 C 1
D 1 4 ? D 1 1 ?
Predicts the rating for the user and Predicts how likely the user buy the
movie pair. item
The matrix includes negative feedback No negative feedback
(Some movies are rated as “boring”) (No reason is given for missing elements)
=> Strong bias toward 1
Only one kind of value for known elements
=> Gives more degree of freedom
A method successful in movie rating prediction is not
useful for recommendation of usual shopping site.
14
16. Solutions
• Regard a zero element as a negative feedback
– Too ad hoc but better than naïve PMF
• Assume a certain ratio of zero elements becomes
one at the optimum [Sindhwani et al. 2010]
– Assign other variables to zero elements and solve a
relaxed optimization
– Experimentally outperform the “zero-as-negative”
method.

2010: 1055-1060

18. Conclusion
• Scientific approach is important
– Math really makes money
• But that alone is not enough for real business
• Engineering matters
– Efficient platform and easy-to-deploy mechanism
• Hand tuning part always remains
– Consulting for parameter tune is essential
