Nawa ne babbar nau'ikan koɗin koɓi (machine learning)?

Question

IT Interview Practice · Accepted Answer

Machine learning yana da nau'uka uku masu mahimmanci — **supervised learning** (koɓi daga misalan da aka labels), **unsupervised learning** (nemo patterns a cikin bayanai marasa labels), da **reinforcement learning** (koɓi ta hanyar yunwa da gaji). Fahimtar su yana bayyana yadda ML ta iske matsaloli daban-daban.

## Nau'uka uku masu mahimmanci

```text
SUPERVISED LEARNING → learn from LABELED data (input → known correct output):
  → trained on examples with answers → learns to predict outputs for new inputs
  → for: classification (categorize), regression (predict numbers)
  → e.g. spam detection (labeled spam/not-spam), price prediction
UNSUPERVISED LEARNING → find patterns in UNLABELED data (no given answers):
  → discovers structure/groupings on its own
  → for: clustering (group similar items), dimensionality reduction, anomaly detection
  → e.g. customer segmentation, finding patterns
REINFORCEMENT LEARNING → learn through TRIAL and ERROR with REWARDS:
  → an agent takes actions, gets rewards/penalties, learns to maximize reward over time
  → for: game playing, robotics, control, decision-making
```

## Zaɓar nau'i

```text
→ have LABELED data + want to predict outputs → SUPERVISED (most common in practice)
→ have unlabeled data + want to find structure → UNSUPERVISED
→ an agent learning from interaction/rewards → REINFORCEMENT
→ (also: semi-supervised, self-supervised — hybrids; LLMs use self-supervised learning)

Fahimtar nau'ukan babbar koɗin koɓi (machine learning) yana da asali domin suna wakiltar **hanyoyin asali na ML ta iske matsaloli**, saboda haka fahimtar su ita ce sahihon koɗin koɓi.

Nau'uka uku kowane yana dace da matsaloli daban-daban da bayanai.

Fahimtar **supervised learning** (koɓi daga bayanai masu labels inda inputs suna da sanannu abubuwan daidai, don tunanin abubuwan kofa ga sabuwan inputs, ana amfani da ita don classification da regression — nau'i da aka fi amfani da shi a aiki, misali spam detection da price prediction) ita ce mafi mahimmancin nau'i na fahimta, domin tana tsari ga gidan yawancin aikace-aikacen ML a duniya.

Fahimtar **unsupervised learning** (nemo patterns a cikin bayanai marasa labels ba tare da bayani da aka ba, gano structure da groupings, ana amfani da ita don clustering, dimensionality reduction, da anomaly detection, misali customer segmentation) yana bayyana yadda ML ta nemo patterns ba tare da labels ba.

Fahimtar **reinforcement learning** (koɓi ta hanyar yunwa da kuskure tare da gaji, inda agent ta ɗauki ayyuka da koɓi don sa haɓaka gaji, ana amfani da ita don wasan baje, robotics, da control) yana bayyana hanyar koɓin da ta dace da hulɗa.

Fahimtar **yadda za a zaɓi** — supervised lokacin da kaka labels bayanai kuka bukaaci tunanin abubuwan kofa, unsupervised don nemo structure a bayanai marasa labels, reinforcement ga agents da ke koɓi daga hulɗa — da cewa akwai hybrids (semi-supervised, self-supervised, tare da LLMs da ke amfani da self-supervised learning) yana nuna fahimtar practical na ML approaches.

Wanan nau'uka ita ce sassan asali na yadda ML ta koɓi, da fahimtar su ita ce mahimmancin aiki don jira da amfani da ML.

Do jiya nau'ukan babbar koɗin koɓi (supervised, unsupervised, reinforcement) suna wakiltar hanyoyin asali na ML ta iske matsaloli da fahimtar su da lokacin kowa ya dace ita ce sahihon koɗin koɓi, fahimtar nau'ukan babbar koɓin koɗi ita ce mahimmancin basirar ilmi — sassan asali na ML (koɓi daga labels, nemo patterns, koɓi daga gaji), sahihon koɗin koɓi don fahimtar yadda ML ta iske matsaloli daban-daban, da mahimmanci don aiki tare da ko jira ML.
