When I exported from pytorch to onnx to TRT, I observe that the output of my model is unstable, and the output confidence of my model tends to drop by 5-10%. In your model, how different is the output of TRT from the output of the pytorch model on a specific frame. If they are...
One of the main concerns about fairness in machine learning (ML) is that, in order to achieve it, one may have to trade off some accuracy. To overcome this
"EvaluationParameters":{"BackTestWindowOffset":10,"NumberOfBacktestWindows":2} HPO and AutoML By default, Amazon Forecast uses the0.1(P10),0.5(P50), and0.9(P90) quantiles for hyperparameter tuning during hyperparameter optimization (HPO) and for model selection during AutoML. If you specify cus...
Furthermore, ethnicity can also be inferred from site-specific signatures, which must be accounted for to ensure equitable application of DL. These site-specific signatures can lead to overoptimistic estimates of model performance, and we propose a quadratic programming method that abrogates this bias...

This study aims to develop a deep learning model to improve the accuracy of identifying tiny targets on high resolution remote sensing (HRS) images. We propose a novel multi-level weighted depth perception network, which we refer to as MwdpNet, to better capture feature information of tiny tar...
dataset for model training. This is particularly relevant in applications where the cost of strain phenotyping is a limiting factor, as this places an upper ceiling on the number of variants that can be screened. The challenge is then to design a limited set of variants so that the resulting...
