Numeric Big Data Analytics for Successful Decision Making: A Case Study from the Retail Industry in Canada
Bibliographic record
Abstract
This paper proposes that the successful analysis of big data in the retail industry is the key to successful business practice, and is an essential ingredient for successful decision making in many industries. In this paper, we present a case analysis of the use of numeric big data analytics to discover the decline in profits while sales figures are rising during promotion weeks at a Toronto-based retail chain store. We also discuss why big data analytics should be seen as a key practice in the retail industry due to the massive amounts of data that is generated in a daily basis, especially, in the retail food industry. The paper sheds light on the ability of analysts to transform the massive amounts of data into information and knowledge to discover hidden problems and make wise management decisions. If properly analyzed, big data can produce the needed information to uncover internal strengths and weaknesses, and external opportunities and threats, and to make data-informed management decisions.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
