- 📣 I'm planning to organize an online series of webinars/workshops, focused on #chemometrics and #MachineLearning for #spectroscopy (using #Python )I'd like it to be beginner-friendly and informal. 🆓 Free registration 🏛️ Tutorial and research talks (including guest speakers and workshop sessions)📅 Monthly or fortnightly schedule💻 Fully onlineIf it sound like you may be interested, please read more and register your interest herehttps://nirpyresearch.com/nirpy-webinars/#Webinar
- If your #spectroscopy dataset is small, deterministic data subdivision into training and test sets may be the way to go 🔬The SPXY algorithm is an extension of the Kennard-Stone method that selects training samples to maximize coverage of both spectra (X) and response variable (Y) at the same time. Here's a primer, with a #Python implementation for #NIR spectroscopy.https://nirpyresearch.com/spxy-algorithm/#Chemometrics #MachineLearning

- Dumb NMR question. Why don't we see splitting from 35Cl or 37Cl in the solvent signal when we run either 1H or 13C NMR? Is it being decoupled as with {1H}13C or does it have something to do with the gyromagnetic ratio or???? #NMR #coupling #decoupling #spectroscopy #chemistry #chemchat #help

- I learnt about the "entropy of the derivative" or delentropy from the paper linked. The idea is that the standard formula for information entropy doesn't distinguish between permutations. The entropy formula −∑p(x)logp(x) depends on p(x) which, absent any extra information about a signal, is estimated by the histogram of that signal.Now, if we do a random permutation of the values of the signal, the histogram doesn't change, so the entropy doesn't change. To find an 'entropy metric' that accounts for that we need to go to the second order, calculating the entropy of the signal derivative.The delentropy is sensitive to […]
