TechShortsApp — V2.1.0 Updates

🔹 Feed Architecture

• Introduced three distinct feed modes:
• For You — personalized videos based on user interests + credibility
• Most Trusted — credibility-first ranking across the platform
• New & Emerging — freshness-first videos with light credibility gating

Credibility and freshness are now treated as separate signals, not mixed.

🔹 Ranking Improvements

• Domain-specific time decay refined

Each domain now decays at its own pace (e.g. AI faster, Engineering Math slower).

• Bayesian confidence correction
• Maximum variance corrected to 1 / 12 (mathematically consistent)
• Reduces overconfidence in low-evidence videos

🔹 Skip Interpretation Upgrade

User skips are no longer treated as uncredible by default:

• Skips are interpreted based on user interest context
• Videos are only penalized when evidence supports lack of credibility
• Rewatched or already-seen videos are protected from penalty

🔹 Personalization Logic

• For You feed now:
• Activates only after sufficient interaction evidence
• Uses user-domain interest + credibility signals
• Cold-start behavior improved (no false penalties)

🔹 Freshness Handling

• New & Emerging feed
• Prioritizes newly uploaded videos
• Still lightly gated by credibility to reduce noise

🔹 System Stability

• Fixed edge-case ranking inconsistencies
• Improved handling of missing credibility timestamps
• Cleaner separation of ranking responsibilities across feeds
