Afternoon with Tomasso on the limitations of Artificial intelligence’s application

For us to be able to successfully apply artificial intelligence on any domain, the following needs to be true

  • The behavior the system to be modeled must not be stochastic
  • The state of the system must be decipherable by the data scientist
    • it should be possible to understand the state in which the system is at through interpretation of data gathered
  • The domain can be modeled
    • the parameters for modeling the domain must be well defined

Only when all three premise are true can we determine where the adjustment should be made when a model fails to predict an outcome

The financial markets is stochastic  in the short run.

The underlying parameters are constantly changing and thus hard to model due to the emergent nature of impacts caused by human activities. The data is qualitative and thus hard to convert into clean quantitative datasets.

While the price movements are obvious it is hard, it is hard to attribute impact to the various parameters.

As such, it requires human neural networks that consumed all these qualitative data to perform the prediction/decision making.

Insights from evening with Wine and Jam session with Adriene and Dennis, Birthday party with Konstantine

From Tommaso on Machine Learning – Economics

  • Study was done on Italy
  • Voting patterns can be leading indicators for credit spread
  • When a political party is stable, Eigen distance between votes of party members will cluster together, even for bills that are not critical for parties
  • When a political party becomes unstable, the Eigen distance between vote on non-critical bills by party members will increase
  • Alignment will increase before a wild swing to misalignment
    • periods of high alignment leads to very tight credit spread
    • tight credit spread indicates a very high price for bond
  • Misalignment will decrease before consolidation towards alignment
    • periods of low alignment leads to very wide credit spread
    • wide credit spread indicates a very low price for bond
  • proposed strategy:
    • when alignments increase, short bonds in anticipation for forthcoming misalignment
    • when misalignments increase, long bonds in anticipation for forthcoming alignment
