まずは、素うどんのXGBoostにかけて、plot_importance, feature_importances_を確認する。しかる後に、各特徴量をF-SCOREの高い順にExploratory Data Analysis (EDA)を行い、データに対する感覚を掴む。特徴量の数が少ないのであれば、初めからEDA。 情報を含まないcolumnsを除く。[Kaggle Kernel: R, Python] 標準偏差が0の説明変数 (constant cols) を除く。 重複した説明変数 (duplicated cols) を1つだけ残して他を除く。 相関係数が1である説明変数の組 (perfectly correlated cols) を探し、1つだけ残して他を除く。 各列について、値が0である説明変数の数を数えて、合計値を追加の説明変数として加える (count 0 per row)。逆
This project was an iterative creative endeavour; we've cleaned up the code a bit, but acknowledge that it is not the prettiest thing you'll ever see. Apologies in advance for any pain caused. That said, we hope you find some bits of it useful or interesting. The figure below illustrates the overall structure. The two most important <div> elements are the #sections and #vis elements, which play th
Image Understanding is becoming a vital feature in ever more applications ranging from medical diagnostics to autonomous vehicles. Many applications demand for embedded solutions that integrate into existing systems with tight real-time and power constraints. Convolutional Neural Networks (CNNs) presently achieve record-breaking accuracies in all image understanding benchmarks, but have a very hig
