Show HN: CVJ-1 VJ Deck / VISUALZ audio-reactive VJ software

https://www.visualzstudio.com/vj-deck

Hey HN —I’ve been building real-time audio-reactive graphics software for the past 7 years. It started as a side project while working full-time as a software engineer, and slowly evolved into VISUALZ — a GPU-accelerated VJ engine focused on low-latency audio analysis, and reactive visuals.Two years ago I decided to take it further and prototype dedicated hardware: the CVJ-1. It’s essentially a...

It will be back. Hopefully soon.

I've been experimenting with this a lot. My code is all public still because I haven't made any giant gains or anything. But I have seen some success here and there. I've even got this one bot that learns from its past trades via ML and uses what it has learned to decide wether to make future trades or not. https://github.com/madchops1/Dutchess.ai

Why can't people just donate their money directly. Why do they have to send you crypto so that you can donate their money?

I apologize. I can do that. I'm going to generate that backtest you described.

Right now I have residual data from the AWS machine learning data that tells me weather there is any structure to the times it does guess wrong. And a value below baseline is a better than 50/50 guess according to what I have learned about how AWS does its ML. Knowing that I use this personally as a supporting indicator to my trade decisions. Since its so new and I really don't want people to think I'm scamming or something. I'm just releasing my results free for now, not trying to be a douche ;)

AWS defines the baseline as follows

Baseline RMSE Amazon ML provides a baseline metric for regression models. It is the RMSE for a hypothetical regression model that would always predict the mean of the target as the answer. For example, if you were predicting the age of a house buyer and the mean age for the observations in your training data was 35, the baseline model would always predict the answer as 35. You would compare your ML model against this baseline to validate if your ML model is better than a ML model that predicts this constant answer.

Also doing random not sequential training and evaluation. The proper way to eval time-series models.

Updated White Paper. Generated more evaluations and back tests. https://s3.amazonaws.com/karlcdn/Dutchess.ai+White+Paper.pdf
Re:Machine learning predictions for QM eMini Crude Oil on Wednesday September 27, 2017 @11:14PM (#15354275)
I did another back test with a randomly selected 70%/30% training to evaluation ratio for evaluating time-series models. Adding results to whitepaper. The results are still under baseline.
Re:Machine learning predictions for QM eMini Crude Oil on Wednesday September 27, 2017 @11:05AM (#15348463)
ya it contains the evaluation results of the model and 5 days of result data.
Re:Machine learning predictions for QM eMini Crude Oil on Tuesday September 26, 2017 @02:38PM (#15341419)
Basically I have a dataset and I train my model with 70% and then evaluate its guesses against the remaining 30%. Hence a baseline is created and I can see if my model performs better.

It took some doing to get this model to perform well. I did this by adding features that help recognize patterns in the time series data.

The features I created are not specific to QM as they are technical (eg. numbers, not news), and time-series related. So the models should work with any historical dataset with the same fields.

My goal is to add another future at some point.

Thats also what the evaluation of an ML model is for.
Re:Machine learning predictions for QM eMini Crude Oil on Tuesday September 26, 2017 @02:27PM (#15341329)
Thats true. I'm going to keep going.
Re:Machine learning predictions for QM eMini Crude Oil on Tuesday September 26, 2017 @02:26PM (#15341322)
I am not trading purely on these numbers. They are indicators they help me make my trading decisions and I think they may help others too.

My models evaluations are performing better than baseline when trained with 70% of the data and evaluated against the remaining 30% so I take that as value. As someone else put it a potentially "favorable guess". At this point I'm using the predictions regularly. And I guess I'll know more the longer I keep track of daily results.

Re:Machine learning predictions for QM eMini Crude Oil on Tuesday September 26, 2017 @02:21PM (#15341278)
I experimented with the features until I got good results in my evaluations. If I am getting favorable guesses, how does that point to bad features. Favorable guesses is what I was going for in order to assist in trading decisions.

I use a 70/30 split of training/eval

Re:Machine learning predictions for QM eMini Crude Oil on Tuesday September 26, 2017 @02:18PM (#15341249)
I am doing my training/evaluation with a data split of 70/30. Doesn't that qualify as a proper backtest?
Re:Machine learning predictions for QM eMini Crude Oil on Tuesday September 26, 2017 @02:18PM (#15341247)
I published the evaluation results in the whitepaper. I am doing my training/evaluation with a data split of 70/30. Doesn't that qualify as a proper backtest?

Also you should always place a stop and limit order. So you don't get completely wiped out. Its very common.
