The 18th Chemometrics in Analytical Chemistry Conference will be held on 29 August-02 September, 2022 in Rome (Italy). All info here: https://cac2022.sciencesconf.org/
ChemTastesDB is a database that includes curated information of 2944 molecular tastants. For each molecule the following information is provided: name, PubChem CID, CAS registry number, canonical SMILES string, class taste. The molecular structure in the HyperChem (.hin) format of each chemical is provided. The database is now available on Zenodo: https://zenodo.org/record/5747393#.Yhnx8ujMKUk
Our paper dealing with the application of multitask neural networks to predict molecular activity on nuclear receptors is now published, have a look here: https://doi.org/10.1002/cem.3325
Il prossimo Workshop del Gruppo di Chemiometria si terrà a L’Aquila dal 30 maggio al 1° giugno 2022. Il Workshop manterrà l’impostazione tradizionale: ciascun gruppo di ricerca/ente/azienda/singolo partecipante potrà richiedere uno slot temporale personalizzabile (tra 10 e 60 minuti) per la presentazione orale delle proprie attività chemiometriche in ambito di di ricerca, didattica e applicazioni.

Today Cecile Valsecchi successfully defended her PhD thesis: “Advancing the prediction of Nuclear Receptor modulators through machine learning methods”. She studied potential interactions between chemicals and nuclear receptors, with the dual purpose of developing in silico tools to search for new modulators and to identify possible endocrine disrupting chemicals.
Congrats! Really a great job!

A new release of the Kohonen and CPANN Toolbox (for Matlab) is now available! The toolbox is a collection of MATLAB modules for calculating Kohonen Maps and Counterpropagation Artificial Neural networs (CPANNs), Supervised Kohonen networks and XY-fused networks. In this new release, it is possible to have calculation on a GPU and RAM usage has been optimised to better deal with big data. The toolbox can be downloaded here.
We compared different appraoches for optimisation of multitask neural network hyperparameters on QSAR data, results were recently published in the following manuscript: Valsecchi, C., Consonni, V., Todeschini, R., Orlandi, M., Gosetti, F., Ballabio, D. (2021) Parsimonious Optimization of Multitask Neural Network Hyperparameters, Molecules, 26, 7254 Have a look here!
Welcome to Veronica Termopoli, new member of the Milano Chemometrics and QSAR Research Group! Veronica has a strong background on chromatography and she will give her introductory seminar “New instrumental and applicative approaches in LC-MS” at our department next wednesday november 10th, more info here.
A new release of the classification toolbox for MATLAB is now available: variance scaling and range scaling have been added as approaches for column pre-processing. Basic row pre-processing methods have been added (standard normal variate, multiplicatve scatter correction, first and second derivative). Savitzky-Golay smoothing can now be applied to analytical spectral data. The layout of the calculation menu has been simplified. Download the latest version here!
