MACHINE LEARNING CHALLENGE I was astonished to get email acknowledgement that my   Kaggle Morse Challenge  was approved today. What gets posted here is permanent in nature, rarely "time sensitive". (I’ve already started using this frequency for SOTA activations near urban areas.). Over the last several years, I've been learning about ham radio repeaters. The illustration below gives an overview of the NN (green: operations, pink: data flowing through NN) and here follows a short description: Note that the model did not know anything about Morse code at the start. The website is running in AWS using serverless Lambda functions and serverless Aurora RDS MySQL database. I starting getting involved in the maintenance of the local machines and have helped troubleshoot and deploy a few here and there. We may have to consider using a omni antenna instead of the Yagi. It has an excellent range of Amateur bands, and even goes down to LF 136KHz and 472KHz, it also has some good decoders built in to play around with for CW, PSK and even WSPR. data needs to stay, shifting it left, and appending the new data. I also enjoy fishing but it is a hobby duty in solitude or with one or two people and ham radio is more social thing. Each matrix-element represents a score for one of the 80 characters at one of the 32 time-steps, The CTC layer either calculates the loss value given the matrix and the ground-truth text (when training), or it decodes the matrix to the final text with best path decoding or beam search decoding (when inferring), 5000 samples, split into training and validation set: 95% training - 5% validation, Each sample has 2 random words, max word length is 5 characters, Morse speed randomly selected from  [20, 25, 30] words-per-minute. !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); Also available via RSS feed, Twitter, and Facebook.
