[D] do you agree “The research on how to deal with time-series data is almost finished”?

here is my question in quora

https://www.quora.com/Why-is-RNN-less-progress-research-than-CNN-especially-the-time-series

question is

Why is RNN less progress research than CNN (especially the time series)?

and answer is

Any problem concerning the images is incredibly harder than that concerns a time series. This is why the research on CNN and its derivatives (U-Net, GAN) are still continuing.

The research on how to deal with time-series data is almost finished. It looks like researchers are trying to come up with better and better techniques, but what is actually happening is people are trying to predict dependencies that are actually not present in the data or using insufficient data!

A good example is the stock value prediction. The simple truth is that the stock prices depend on many more variables that are not present in the typical input time series’ used with RNN or LSTM.

My personal opinion is now LSTM is SOTA but I think another SOTA network will be created.

how about think of this topic?

[D]All Things Interesting Podcast: Kasian Franks of Vectorspace AI

Hi everyone,

I’m those host of the All Things Interesting Podcast and wanted to drop in to share my first interview with blockchain startup technical cofounder Kasian Franks.

Kasian and his team at Vectorspace AI are working on bridging blockchain with context controlled vector based NLP/NLU to power AI and machine learning. In this episode, we talk about all things AI, ML, NLP/NLU, and blockchain.

[D] Machine Learning Infrastructure with Amazon SageMaker and Terraform — A Case of Fraud Detection

Good day!

Here’s an article I wrote on setting up Amazon SageMaker with Terraform, based on the example from AWS Solutions.

https://medium.com/@qtangs/machine-learning-infrastructure-with-amazon-sagemaker-and-terraform-a-case-of-fraud-detection-ab6896144781

Source code can be found here: https://github.com/qtangs/tf-fraud-detection-using-machine-learning

I’d love to hear feedback from the community.

Please note, though, that I’m a noob in machine learning, so pardon my ignorance in many areas.

Thanks!

[D] Do you have an idea for a machine learning library or framework that you’ll probably never get around to making, and wish someone else would make it?

I’m going to a 2 day machine learning hackathon. 2 days isn’t a lot of time to train a brand new model, so I’m hoping to make something that would assist other ML people. 2 days will probably just be enough time for a prototype with core functionality.

If it makes a difference, I’ll be working in Pytorch.

[D] Are Graph Convolution Networks (GCNs) with graph constraints possible?

[D] Are Graph Convolution Networks (GCNs) with graph constraints possible?

Greetings,

I am very new to the area of machine learning, so excuse what may appear as a stupid question.

I am interested in using graph convolution networks for semi-supervised classification of nodes in a graph. I would like to impose a graph constraint on the network. I have included an image to illustrate

Constraining node classification of a GCN with a graph constraint (connectivity of communities).

The graph constraint I want to impose is that there can only be one communities/region for each label (blue, green, red). In the above figure you can see a sample resulting GCN classification that produces two green communities/regions. I was thinking that perhaps there is a way to create a community/region graph from the resulting GCN algorithm then I compare that with the constraint graph. That comparison, or similarity measure, would be incorporated into some loss function and somehow back propagate that back into to GCN and finally arrive at a classification where there is only one community/region per label.

Is this possible? Is there a better way to approach this (perhaps using an doing some graph embedding or autoencoder/decorder technique)?

Thanks for any suggestions or comments 🙂
