Is it possible to clean up an audio recording of a lecture using some type of AI system?

Yes, it is possible. Usually, the noise reduction is done using regular signal processing methods, such as spectral subtraction due to demand for low latency. But, of course, modern methods of deep ...

How much of a problem is white noise for the real-world usage of a DNN?

The white noise that fools DNNs isn't really white noise. It has been altered in the same way as the synthetic misclassified pictures have been altered. You have to change many input pixels in exactly ...

Can I reduce the "number of weights" in CNN to 1/3 by restricting the input as greyscale image?

After inner product, add them all to make one feature map. Am I right? yes, you are right. Then, can I reduce the number of weights in the filters? Because in this case, using three different n×n ...

What is a temporal feature?

In general, the expression "temporal feature" might refer to any feature that is associated with or changes over time. However, in the context of signal processing, a temporal feature might ...

Is it a good practice to pad signal before feature extraction?

Padding is a common practice both in image-processing (typically via CNNs) and in sequence-processing tasks (RNNs, Transformers). For CNNs all the standard convolutional layers - Conv1D, Conv2D and ...

Which type of feature extractor do you suggest to classify sensor data?

There could be multiple possible ways to extract the features. One would be to use RNNs for a temporal relationship as the input data is time-series.

Aren't all discrete convolutions (not just 2D) linear transforms?

The convolutions are linear transformations. However in typical applications a non linear activation function like RELU is used following the convolution to provide non-linearity otherwise a ...

Analyzing vibration using machine learning

If you want to use machine learning for such a project, you can use vibrations data directly, and treat the problem as a regular audio classification problem. A simple approach would be to use a ...

How can I remove the noise from an EEG signal?

If the noise is confined to a particular spectral band, Fourier transform followed by filtering, followed by an inverse Fourier transform will work. If it is multiplicative noise, filtering the ...

How can I remove the noise from an EEG signal?

This might be more of a signal-processing question, rather than a artificial intelligence question, but I will try my best to be of help. Do you know what the noise you are trying to remove is? How ...
