Ralph Winters commented on Matt Tucker's blog post The Death of the Data Scientist
"Not sure I understand your example about the failings of a neural network vs. the "workable" linear regression solution.  Why invest your time and money on complex algorithms that are impossible to understand and maintain, when…"

Ralph Winters commented on William Vorhies's blog post Data Science is Changing and Data Scientists will Need to Change Too – Here’s Why and How
"If everything else is automated and optimized, why not feature engineering?  Software can feature engineer this as well, better than humans.  So, everything will eventually need to be model validated by humans.  The problem is that…"

Ralph Winters commented on William Vorhies's blog post Why R is Bad for You
"The advantage of having a GUI based predictive modeling environment cannot be over emphasized if true collaboration is desired among all stakeholders in a data science project.  Often code based implementations can be siloed…"

Ralph Winters commented on William Vorhies's blog post Why R is Bad for You
"Good headline, but I don't think it as dire for R as your article makes it out to be. It is true that drag and drop encourages more collaboration among different participant skill levels (including some managers). In fact, one article I read…"

Ralph Winters commented on L.V.'s blog post Data scientist paid $500k can barely code!
"There are many quants or traders in the financial domain , who work with their own tools (no R, no Python, no SAS)  who could easily call themselves data scientists. All they need to do is develop 1 hedging strategy which yield multiples of…"

Ralph Winters commented on William Vorhies's blog post 3 Tips for Getting the Most Out of Your Data Science Team
"Bill - Thanks for your viewpoint.  I agree with a lot that you say. don't think the common single  platform argument holds as well today as it used to.  Certainly there is an advantage to having different orientations towards the…"

Ralph Winters commented on William Vorhies's blog post How NoSQL Fundamentally Changed Machine Learning
"No doubt that NoSql has added to our ability to capture and store the data. Unfortunately, I think the analytics or Machine Learning part is still behind in terms of the ability to directly analyze the large storage, and we still have to resort to…"

Ralph Winters commented on Vincent Granville's blog post Data science without statistics is possible, even desirable
"Apparently, IBM trusts 'old' logistic regression enough to incorporate it as the basis of Watson for ranking Jeopardy answers. Food for though when considering the stability of a 'new' vs. 'old' technique. See:…"

Ralph Winters commented on William Vorhies's blog post The Value of Accuracy in Predictive Analytics
"One could also make the argument that If a small improvement in the model accuracy make a big difference in the results, possibly the model is not as robust as you would like, and could need constant monitoring."

Ralph Winters commented on William Vorhies's blog post Prescriptive versus Predictive Analytics - A Distinction without a Difference?
"OK.  I get it.  Prescriptive Analytics is sort of predictive analytics with optimization and scenario 'what-ifing' built in. True.  We've been doing this for years.  However, this definition does seem to make the…"

Ralph Winters commented on William Vorhies's blog post Prescriptive versus Predictive Analytics - A Distinction without a Difference?
"If you a believer in the Gartner Hype Cycle "Predictive Analytics" has reached the Plateau of Productivity, and thus fallen off the chart, while "Prescriptive Analytics" has appeared and is making its climb towards the "Peak…"

Ralph Winters commented on Michael Walker's blog post Big Data is Stupid Data
"If we had the same level of tools for "Big Data" as we did for "Small Data", We could do better.   But you are correct, "Big Data" is forcing us into a "Forest beyond the Trees" type of scenario, in…"

Ralph Winters commented on William Vorhies's blog post How to Become a Data Scientist
"Some good points.  I'm just trying to comprehend the interpretation of the two language graphs. Why would the first graph show Java, SAS, and Python as the top 3 with the most (analytic) jobs, while the 2nd graph show R, SPSS, and SAS with…"

Ralph Winters commented on Ryan Montano's blog post Data Scientist, please meet the Data Artist
"Quite poetic with beautiful images. Unclear as what the point is regarding Data Science.  Are you saying it is more of a creative, rather than an objective discipline? A scientist is still a scientist and not really an artist!"

Ralph Winters commented on Vincent Granville's blog post The Data Science Equation
"Vincent - How are you measuring "statistically validity of data science related fields"? If you statistical validity for "top data scientists" is weak, what would be the basis for using them as the sample in your other blog?"
