Thesecond stepin calculating self-attention is to calculate a score. Say we’re calculating the self-attention for the first word in this example, “Thinking”. We need to score each word of the input sentence against this word. The score determines how much focus to place on other parts ...
How to calculate Jaccard, is there any specific code, my calculated Jaccard is incorrect @jia-er I found the Jaccard computation in the repo in LSTM_TrajGAN_measurement.ipynb. It's computed as the Intersection divided by the Union (IOU) of the convex hull areas of the trajectories. Sign...
In this tutorial, you discovered how to encode your categorical sequence data for deep learning using a one hot encoding in Python. Specifically, you learned: What integer encoding and one hot encoding are and why they are necessary in machine learning. How to calculate an integer encoding and...
% Calculate RMSE rmse(t) = sqrt(mean((yTrain - yPred(2:end)).^2)); % Compare with actual values end disp(rmse); % Display RMSE for each iteration This will allow you to monitor the performance of your model throughout the forecasting process. Hope this helps...
Before we can fit an LSTM model to the dataset, we must transform the data. The following three data transforms are performed on the dataset prior to fitting a model and making a forecast. Transform the time series data so that it is stationary. Specifically, a lag=1 differencing to remove...

To calculate the gradient, we used the Python function numpy.gradient. The gradient provides a measure of the rate of increase or decrease of the signal; we consider the absolute value of the gradient, to account for the magnitude of change rather than the direction of change. To identify ...
The final of the decoder's process involves a linear layer, serving as a classifier, topped off with a softmax function to calculate the probabilities of different words. The Transformer decoder has a structure specifically designed to generate this output by decoding the encoded information step ...
After forecasts have been made for each step in the test dataset, they need to be compared to the test set in order to calculate an error score. There are many popular errors scores for time series forecasting. In this case, we will use root mean squared error (RMSE), but y...
Next, we need to center the values in each column by subtracting the mean column value. 1 C = A - M The next step is to calculate the covariance matrix of the centered matrix C. Correlation is a normalized measure of the amount and direction (positive or negative) that two columns ch...
