Autoencoder. As you read in the introduction, an autoencoder is an unsupervised machine learning algorithm that takes an image as input and tries to reconstruct it using fewer number of bits from the bottleneck also known as latent space.

Steps Per Epoch. It is useful if you have a huge data set or if you are generating random data augmentations on the fly, i.e. infinite size. steps_per_epoch is batches of samples to train. It is used to define how many batches of samples to use in one epoch. It is used to declaring one epoch finished and starting the next epoch.Recall, after each epoch, the algorithm moves back through the network to tweak the weights. Notice, however the RMSE is quite large (ranging from above 1.3 to below 0.8), especially in relation to the data, which has been normalized to have a mean of zero and a standard deviation of one for each successive 10-month period. ... we plot the loss ...Oct 02, 2019 · It is said that it is ideal to plot loss across epochs rather than iteration. During an epoch, the loss function is calculated across every data items and it is guaranteed to give the quantitative loss measure at the given epoch. But plotting curve across iterations only gives the loss on a subset of the entire dataset.

Practice implementing gradient descent. This will implement the basic functions of the Gradient Descent algorithm to find the boundary in a small dataset.Introduction to LSTM. LSTMs (or long-short term memory networks) allow for analysis of sequential or ordered data with long-term dependencies present. Traditional neural networks fall short when it comes to this task, and in this regard an LSTM will be used to predict electricity consumption patterns in this instance.

On the x-axis, we plot the number of epochs, and on the y-axis, we plot the different loss values. As we have trained our network for 100 epochs, you can see that there is a very nice curve, which shows how well our models are learning. A reduction in the loss value shows a promising improvement in the model's performance.

Once the model creation is done, we can proceed to compile and fit the data. The output produced by each epoch is stored in the history object which is later used to plot the graph of accuracy vs. epochs. This is used to determine the performance of the model and make sure that it is not over-fitting.These are the same as in-sample, which is hardly surprising because the model is stationary, and the data in the out-of-sample case was produced by the same data-generating process. We show the plot of actual versus model-predicted prices, and see that they are highly accurate. See Figure 11.7. epoch: 1 epoch means training all samples one time. In our training example, we have 60000 examples to train and we selected a batch_size of 100. So, for one epoch we need (60000/100) = 600 iterations. I have trained this model several times and found that in 10 epochs (approx.) the CNN reaches 99% (approx.) test accuracy.
