oct 08, 2019 oct 08, 2019 manually saving weight is just as simple with the model.save_weights method. model.save_weights(filepath='final_weight.h5') load weight into the model. when restoring a model from weights-only, you must have a model with the same architecture as the original model. so first create a new, untrained model and evaluate it on the test set.

aug 06, 2019 aug 06, 2019 if you train a model from scratch then it will eventually learn all the patterns which using a pre-trained digits classifier weights would have learnt. on the other hand using weights from a dog-vs-cat classifier should give you better performance as it already has learned features to detect say paws, ears, nose or whiskers.
aug 31, 2018 this model is equivalent to the one above. categorical variables, in other words, provide a lot of leeway in how the model can assign its weights. it’s literally random. dependent variables also provide free parameters. suppose it turns out that, in your real-world dataset, larger coins are also thicker. then, your model might just as well as be:
observation weights used to train the model, returned as an n-by-1 numeric vector. n is the number of observations ( numobservations ). the software normalizes the observation weights specified in the weights name-value argument so that the elements of w within a particular class sum up to the prior probability of that class.
sep 09, 2017 1 answer1. after training the model with estimator, you could use the tf.train.load_variable to retrieve the weights from checkpoint. you can use tf.train.list_variables to find the names for model weights. there are plans to add this support in estimator directly also.
aug 20, 2018 aug 20, 2018 rickyfox's answer is great in explaining how the weights influence the results of a classifier, but maybe could you be also interested in why / how we would need such weights in the first place (which is more a statistical problem than a purely ml one).. sometimes the observed data is observed with different distributions and we need to use sampling weights to account for it.

jul 20, 2018 jul 20, 2018 but remember the task at hand is to use the above-trained model's encoder part to classify the fashion mnist images. so, let's move to the next part now! save the model. since you will need the encoder weights in your classification task, first let's save the complete autoencoder weights. you will learn how you can extract the encoder weights soon.
visualization of mlp weights on mnist sometimes looking at the learned coefficients of a neural network can provide insight into the learning behavior. for example if weights look unstructured, maybe some were not used at all, or if very large coefficients exist, maybe regularization was too low or the learning rate too high.
we will name the model as classifier as our aim is to classify customer churn. then we use the sequential module for initialization. #initializing neural network classifier = sequential() ... we also optimize the weights to improve model efficiency. for this, we have to update the weights.
