The Four Pillars

1280D Aesthetic Embeddings

Upgraded to MobileNetV4-Conv-Small delivering 2.2x more detailed style recognition. The model maps wallpapers into a 1280-dimensional embedding space, processing composition, contrast, and color palette semantics 100% on-device.

Inference: MobileNetV4 (TFLite) Aesthetic Features: 70% Weight

MODEL: MNV4_SMALL |||| || | |||| ||| 1.28K

Liquid Glass UI

A smart Jetpack Compose workaround for background blurs. Vanderwaals pre-renders blur slices once, applying 80px Gaussian blur, chromatic aberration, and barrel distortion to create frosted layouts with 0% runtime GPU lag.

Blur Layer: 80px Gaussian Rendering: Slice-based

RENDER: GL_BLUR || |||| ||| | 80PX

Implicit Learning Loop

No tedious survey required. An Exponential Moving Average (EMA) algorithm learns directly from feedback and screen activity. Wallpaper duration acts as implicit feedback—quick changes signal a dislike, while longer keeps reinforce weights.

Loop: EMA Preferences Curation: Implicit + Explicit

LOOP: EMA_PREF |||| | || | ||| EMA

System Optimization

Pre-caching background threads make wall swaps near-instant (~5s). Includes a dedicated Keep-Alive foreground service and WakeLock parameters specifically optimized for Samsung One UI's battery restrictions, preventing auto-change shutdowns.

Memory: ~40MB peak Quantized Manifest: ~6MB

SYS_OPT: SAMSUNG_ONEUI || | |||| ||| ||| ~40MB

Audited Security.

Vanderwaals restricts network communication solely to wallpaper catalog synchronization. The app strips invasive tracking, and uses code minification to remove unused classes.
