Why is naïve Bayes generative?

I am working on a document which should contain the key differences between using Naive Bayes (generative) and Logistic Regression (discriminative) models for text classification. During my research, I ran into this definition for Naive Bayes model:…

Linear Discriminant Analysis vs Naive Bayes

What are the advantages and disadvantages of LDA vs Naive Bayes in terms of machine learning classification? I know some of the differences like Naive Bayes assumes variables to be independent, while LDA assumes Gaussian class-conditional…

Google Kubernetes Engine vs Vertex AI (AI Platform Unified) for Serving Model Prediction

With Google releasing Vertex AI lately that integrates all its MLOps platforms, I wonder what would be the difference in serving a custom trained PyTorch/Tensorflow model on GKE vs Vertex AI (or AI Platform Unified, since the rebranding just took…

Learning Binary Decision Diagrams (BDDs) from data in Python

Is it possible to learn Binary Decision Diagrams (BDDs) from data (as in a machine learning fashion)? If so, how? Background: I've seen some tools in Python to do this task in e.g., Decision Trees (DTs) with scikit-learn, but I have not seen any for…

Can you explain difference between tensorflow loading and hdf5 loading in keras model

I was trying to load the keras model which I saved during my training.So I went to keras documentation where I saw this. Only topological loading (by_name=False) is supported when loading weights from the TensorFlow format. Note that topological…

Show model layout / design (with all connections) in Keras

I have major differences when testing a Keras LSTM model after I've trained it compared to when I load that trained model from a .h5 file (Accuracy of the first is always > 0.85 but of the later is always below < 0.2 i.e. a random guess). However I…

Using a trained keras model to make predictions without downloading tensorflow?

Basically, I have a trained .h5 model (I'm not married to that format, but it's how I inherited the codebase) and want to provide a way for other people in my lab to use this file for prediction. Right now, the call to load_model() inside…

Custom Keras Augmentation Layer, Cant get Batch Size

I was trying to create custom augmentation layer in Keras. the idea is to make faster augmentations (instead of running same function BATCH_SIZE times, run it once over the whole batch). I got stuck in the function: __call__(inputs, training=False,…
