Majibu na maelezo huonekana unapojibu maswali.

  1. Why can one global forecasting model help when an organization has many related series?
    • It can learn shared patterns across series while retaining series-specific inputs
    • It guarantees the same forecast error for every series
    • It replaces chronological validation with a random split
    • It means one model is trained separately for each series
  2. Kwa nini utabiri wa uwezekano (quantile) ni muhimu kwa upangaji wa hesabu?
    • Wanatoa nambari moja iliyohakikishwa
    • Yanaonyesha anuwai na imani ili wapangaji waweze kuweka hisa za usalama dhidi ya hatari
    • Wanaondoa hitaji la data yoyote ya kihistoria
    • Wanafanya utabiri kukimbia haraka
  3. Ni ipi njia ya utabiri wa takwimu ambayo hutangulia mbinu za kisasa za ML?
    • Kibadilishaji cha Fusion cha Muda
    • KinaAR
    • ARIMA
    • TimesFM
  4. Ni pigo gani muhimu la kuepukwa unapomfundisha mtabiri wa mahitaji?
    • Kwa kutumia vipengele vya kalenda
    • Ikiwa ni pamoja na maelezo ya kukuza
    • Kuzalisha muda wa kujiamini
    • Kuvuja data ya siku zijazo katika mafunzo ya utabiri wa zamani
  5. Ni mawimbi gani ya nje ambayo yangeboresha kwa uwazi zaidi utabiri wa mauzo ya ice cream?
    • Joto la kila siku na hali ya hewa
    • Kumbukumbu za muda wa seva
    • Siku ya kuzaliwa ya Mkurugenzi Mtendaji
    • Chaguzi za herufi kwenye wavuti
  6. What did the cited decoder-only foundation-model paper report about its model’s zero-shot forecasts?
    • It guarantees better forecasts for every business series
    • On several public datasets, out-of-the-box accuracy came close to supervised models trained for each dataset
    • It eliminates the need for statistical baselines
    • It forecasts only with fine-tuning on each target series
  7. What architecture does the DeepAR paper use to produce forecasts across related time series?
    • A single ARIMA model fitted separately to each series
    • A static lookup table of future values
    • An autoregressive recurrent network trained on many related series
    • A diffusion image model that reads plotted charts
  8. Why evaluate a demand model against statistical baselines?
    • To ensure a neural model always wins
    • To make data leakage unavoidable
    • To remove uncertainty from demand
    • To test whether added model complexity improves the target forecast task
