What IT executives are saying about vendor consolidation

CIO Business Intelligence

While there is little doubt that companies have been cutting back on expenses generally in response to economic uncertainty, startups in particular have been feeling the pain of contracting budgets and reluctant investors. At this point in time, it needs to be asked whether such a rapid increase in the number of vendors is sustainable.

Themes and Conferences per Pacoid, Episode 10

Trying to dissect a model to divine an interpretation of its results is a good way to throw away much of the crucial information – especially about non-automated inputs and decisions going into our workflows – that will be required to mitigate existential risk. Because of compliance. Admittedly less Descartes, more Wednesday Addams.

The bucketing method also changes the importance sampling to a stratified sampling setting, and allows us to use binomial confidence intervals to estimate the uncertainty of our estimate (more on that later). High Risk 10% 5% 33.3% 5] Ray Chambers, Robert Clark (2012). Miss-coverage rate with 95% confidence bands. 7] Neyman, J.

Crucially, it takes into account the uncertainty inherent in our experiments. Risk and Robustness Our estimates $widehat{beta}$ of the "true'' coefficients $beta$ of our model (1) depend on the random data we observe in experiments, and they are therefore random or uncertain. It is a big picture approach, worthy of your consideration.

Our quest for robust time series forecasting at scale

Quantification of forecast uncertainty via simulation-based prediction intervals. In the first plot, the raw weekly actuals (in red) are adjusted for a level change in September 2011 and an anomalous spike near October 2012. Such a model risks conflating important aspects, notably the growth trend, with other less critical aspects.

Further, there is the risk that the increased ad spend will be less productive due to diminishing returns (e.g., In practice, the focus of the team is however on the estimate of $beta_2$, not to forget about the uncertainty around this estimate: the confidence interval half-width was estimated to be 0.27.

Data Science, Past & Future

Domino Data Lab

I went to a meeting at Starbucks with the founder of Alation right before they launched in 2012, drawing on the proverbial back-of-the-napkin. What I’m trying to say is this evolution of system architecture, the hardware driving the software layers, and also, the whole landscape with regard to threats and risks, it changes things.
