How does batch size affect model convergence?
I am experimenting with training parameters and I notice that smaller batch sizes seem to take longer to converge but maybe give better generalization? I am confused about the trade-offs here. If I in...
What exactly is a tensor in deep learning terms?
I keep seeing the term 'tensor' used everywhere in TensorFlow and PyTorch. Is it just a multi-dimensional array, or is there a formal mathematical definition that I am missing? It seems like it's the ...
Can someone explain the gradient vanishing problem?
I keep running into the vanishing gradient problem while training my multi-layer perceptron. I understand it has something to do with the chain rule and small derivatives, but I am struggling to imple...
Is dropout useful at test time?
I am confused about dropout. If I am using dropout to prevent overfitting during training, do I need to keep it on during inference? I keep reading conflicting advice online. Some people say turn it o...
Who is actually considered the father of deep learning?
I keep seeing different names thrown around when people talk about the history of artificial intelligence. Some sources point to Geoffrey Hinton, while others mention Yann LeCun or Yoshua Bengio. It g...
Is it worth learning PyTorch if I already know Keras?
I have built several models in Keras, but I see most research papers and job postings asking for PyTorch. Is the learning curve worth it? I feel like Keras is much easier to read and deploy, but I am ...
Is there a way to visualize internal layer activations?
I want to know what my model is actually seeing during training. Is there a library or a technique to extract the activations from hidden layers and visualize them as heatmaps? It would really help me...
Should I use pre-trained embeddings for NLP?
I am working on a text classification project. Is it better to train my own word embeddings from scratch, or should I use something like Word2Vec or GloVe? My dataset isn't huge, so I suspect training...
How can I improve my deep learning math fundamentals?
I am a developer who learned deep learning frameworks like Keras first, but I feel like I am just using black boxes. I want to understand the underlying mathematical foundations better so I can debug ...
How to manage version control for bot code?
We are a team of three developers working on the same RPA projects, and we keep overwriting each other's changes. It is a nightmare. Does everyone use Git for their RPA code, or are there internal too...
