Linear_Regression_From_Scratch Implementing linear regression from scratch in Python. The implementation uses gradient descent to perform the regression. It does take multiple variables. However, it uses a loop based implementation instead of a vectorized, so it's not computationally efficient.About...

In this case we would call it multiple linear regression, but we could no longer use formulas above. class SimpleLinearRegression: def fit(self, X, y): self.X = X self.y = y self.m = ((np.mean(X) * np.mean(y) - np.mean(X*y)) / ((np.mean(X)**2) - np.mean(X**2...

Linear regression is used to decode the true signal strength from the observed data. In visual terms, the task of the model is to decode the color of a dot, based on its location in the graph.A: The simulated data consists of two components. The first component (large dots) dictates ho...

These models use anchor boxes to integrate object classification with localization regression, thereby optimizing the detection speed of the models. Cha et al. [24] identify bridge defects using the two-stage detector Faster R-CNN [19] and enhance the real-time performance by replacing the ...
