mobilenet_v1_050(pretrained: bool = False, overrides: object = {})

source edit

MobileNet-v1 backbone at width multiplier $\alpha = 0.5$ .

Builds a MobileNetV1 with every channel count multiplied by 0.5 — approximately 1.3M parameters. Howard et al., 2017 report 63.7% ImageNet-1k top-1 accuracy with this configuration (Table 7), at roughly 27% of the FLOPs of the full-width model.

Parameters

pretrainedbool= False

Reserved for future pretrained-weight loading. Currently ignored.

**overridesobject= {}

Keyword overrides forwarded into MobileNetV1Config.

Returns

MobileNetV1

Backbone with the MobileNet-v1 ( $\alpha = 0.5$ ) configuration applied (or with overrides merged on top of it).
