#### Blog

From time to time I will write about things. I will list the things here.

- Keep using plate notation Someone was wrong on the internet. In particular, someone expressed their (questionable) beliefs about plate notation. These are my feelings about that.
- Theoretical data science background I: functional optimization First post in a (maybe) multipost series of theoretical background for data scince. Here lie Euler-Lagrange equations, the general supervised learning problem, and time series smoothing.
- Perturbing correlation matrices: on what we can do when we are
presented with a correlation matrix and
*not*with the data that generated it - Continuum rich-get-richer dynamics and survival theory: on the non-obvious connection between the kernel function of a rich-get-richer process and the hazard function of a random variable.

#### Software

`verdantcurve`

: agent-based market model created in collaboration with Colin Van Oort. This package contains- A heterogeneous and extensible set of algorithmic trading agents
- A matching engine that implements a frequent batch auction, a new type of auction mechanism that greatly reduces the effectiveness of high-frequency trading strategies
- A orderbook and multiple types of orders
- A market construct to facilitate interaction between agents and the matching engine

`discrete-shocklet-transform`

: qualitative, shape-based, timescale-independent time series similarity search algorithm
