Optimizer = tf.train.AdamOptimizer(learning_rate=learning_rate).minimize(cost) Lambda_term * tf.nn.l2_loss(biases_hidden) + In this section, we explore different usability testing methods, when you should use them, and why. Lambda_term * tf.nn.l2_loss(weights_out) + Usability testing is a powerful tool for evaluating a website's functionality and making sure people can navigate it efficiently. Udacity provided the baseline values for each metric: For each of the metrics selected as an evaluation metric, calculating the standard deviation given a sample size of 5000 cookies visiting the.

We change lives, businesses, and nations through digital upskilling, developing the edge you need to conquer what’s next. And I want to apply it to notMNIST data to reduce over-fitting to finish my Udacity Deep Learning Course Assignment.I have read the docs of tensorflow on how to call the tf.nn.dropout.
