Trace Analysis Patterns (Part 243)

Sunday, February 18th, 2024

Trace Variance is the measure of variability of traces and logs in different environments. This trace and log analysis pattern metaphor is borrowed from variance in machine learning like Trace Bias. Here, different environments or the same environment at different times are considered as input data.

Other analysis patterns can be used to investigate Trace Variance such as Bifurcation Point, Trace String, and Polytrace.

Trace Analysis Patterns (Part 242)

Sunday, February 18th, 2024

Trace Bias is the measure of how faithfully traces and logs as a models of computation reflect the actual computation. The term bias has many meanings. This trace and log analysis pattern metaphor is borrowed from model bias in machine learning and statistics. Traces, and therefore, their biases range from Empty Traces to Sparse Traces to traces from Time Travel Debugging tools. How we do tracing, for example, via Declarative Traces or Moduli Traces, have direct impact on Trace Bias.
