[导读]GPS L1 C/A信号（1575.42 MHz，BPSK调制，1.023 MHz码率）是软件定义无线电（SDR）入门经典案例。借助RTL-SDR / HackRF / USRP + GNURadio或Python，可完成从原始IQ到NMEA语句的完整处理链路。本文聚焦工程 ...
Feature engineering 是机器学习 pipeline 里最关键的一环。算法再好，如果输入数据噪声大、不一致或者缺乏有意义的特征，模型表现都不会很好 这篇文章用 Pandas 和 Scikit-learn，把一条完整的 feature ...
I won't be supporting any of the existing tools, nor developing functionality that relies on arcpy or ArcGIS Pro toolboxes as a matter of course. Most analysis functionality that is geometry related ...
In this tutorial, we implement an advanced Bayesian hyperparameter optimization workflow using Hyperopt and the Tree-structured Parzen Estimator (TPE) algorithm. We construct a conditional search ...
Hello, today I’m going to review the Particle Tachyon SBC designed for high-performance edge AI, IoT, and connectivity applications. Powered by the Qualcomm QCM6490 platform with an octa-core Kryo CPU ...
[导读]在高速数字通信领域，112G及以上速率的通道传输技术正逐渐成为主流。然而，随着数据速率的提升，信号在传输过程中受到的干扰和损耗也愈发严重。通道去嵌误差是影响高速信号完整性 ...
この本を教科書として勉強しています。アウトプットするとさらに理解できるので。4章のモデルの訓練をやります。 4.4学習曲線 y = 0.5x^2 + 1.0 x + 2 + gaussian noiseの分布を推定するときに、2次で ...
