<p>Yolo is one of the best object detection for real time detection.  Fast Training and high accuracy are competing goals. Did you mean test speed (with a trained model)?</p>

<p>Anyway, if you need fast training I highly suggest the cyclical learning rate strategy <a href="https://arxiv.org/pdf/1803.09820" rel="nofollow noreferrer">proposed</a> by Leslie N. Smith. </p>

<p>Yolo has different version, so take a look at that as well.</p>
Object detection with using keras: which R-CNN models is best?(recognition the navigations symbols)
<p>I'm doing a project these days.<br>
Goal of this project is approximately 200 symbol recognition.<br>
Symbols are using in the navigation(turn_right, turn_left etc..)</p>

<p>I'm using YOLO model now<br>
For traning this models, I thought I needed some improvement about traning speed.<br>
This program will using when testing new navigation.</p>

<p>Is there any better models?<br>
The model needs very fast traning speed, and high accuracy</p>
