<p>If you refer to the Learning Rate Finder (as described by Smith for example here: <a href="https://arxiv.org/abs/1803.09820" rel="nofollow noreferrer">https://arxiv.org/abs/1803.09820</a>), it seems like you can emulate it by using:</p>

<pre><code>learning_rate: {
    exponential_decay_learning_rate {
          initial_learning_rate: 0.004
          decay_steps: 10000
          decay_factor: 1.3
    }
}
</code></pre>

<p>with a decay_factor above 1.</p>

<p>You will still have to look at the loss and choose the best learning rate yourself though.</p>
Finding the best learning rate in tensorflow object detection
<p>I want to search for the best learning rate using tensorflow object detection api. But in the config file I'm not able to find anything for it. I can add <code>schedule</code> but it can't search for the best learning rate.</p>

<pre><code>learning_rate: {
            manual_step_learning_rate {
              initial_learning_rate: 0.003
              schedule {
                step: 6000
                learning_rate: .0003
              }
              schedule {
                step: 12000
                learning_rate: .00003
              }
</code></pre>

<p>Is there any trick or way to search for best learning rate.</p>
