WEEK 02 · ONE HUNDRED REAL BATCHES
Do one thing.
Then you are ahead.
Last week you flew the simulator. This week you open the black boxes of 100 real flights. IndPenSim is a benchmark built by researchers from an industrial-scale penicillin fermentation: 100 batches, each hours long, with temperature, pH, oxygen, feeds, and even Raman spectra, some of them with faults. The first feeling will be overwhelm: dozens of variables, thousands of time points. Your job is the job you have don…
If you only do one thing this week: the tidy parquet of IndPenSim

THE NEXT BLOCK
How long have you got?
By Sunday you should be able to say: “I can explain what a faulty batch looks like in a PCA scores plot and why respiration makes oxygen fall when biomass rises.”
