Breaking barriers into true AI applications we were dreaming of... Stanford Researchers Develop An Incredible Brain-Computer Interface (BCI) System That Can Convert Speech-Related Neural Activity Into Text At 62 Words Per Minute Did you ever imagine that a person who lost his ability to speak and cannot clearly utter words would be able to communicate what he wants to say? This has come true with the incredible advancements in Artificial intelligence and Machine Learning. Several new pieces of research are being carried out, and many algorithms are being instituted to cater to the different needs of mankind. Researchers at Stanford University have developed one such interface. This Brain-computer interface can help a person with a condition like a paralysis to convey his thoughts and communicate at 62 words per minute.

Productive Analytics managers are investigative analytics managers. Top 5 models one should try are (1) XGboost, (2) L1, L2, glmnet regressions, (3) random forest, (4) SVM, (5) regularized NN, if time permits. Usually XGBoost and glmnet (hybrid of L1 and L2), and SVM should be good for most of the purposes that also provides interpretable models, while NN is good for voice/txt/images/videos. - Ask to verify "Be very clear as to which one is "1" or " " - is it target or reference in binary target variable? Also whether confusion matrix takes care of that correctly and hence whether the "key" ratios of row percentages or column percentages . For various internal programming setup in a software, different software or the modeling specific API deals may deal with this differently. Top models will use the leaky data rather than be good general model of the underlying problem. When you are a company providing your data. Reversing an anonymization and obfuscation can result in a privacy breach that you did not expect. It is a problem when you are developing your own predictive models. You may be creating overly optimistic models that are practically useless and cannot be used in production. " The solution is to use proper verification of actual distributional values of validation data set and the inherent data distributions of the features - For more, see: https://lnkd.in/gyWhs2sg
