Cross Entropy

  Top businesses are utilizing machine learning and deep literacy to automate their procedure, decision- making, accretion effectiveness in complaint discovery, etc. How do the companies optimize these models? One way to estimate model effectiveness is delicacy. The advanced the delicacy, the more effective the model is. It’s thus essential to increase the delicacy by optimizing the model; by referring loss functions.    What is  Cross Entropy  Cross-entropy is generally utilized in machine learning as a loss function.   Cross-entropy loss refers to the discrepancy between two aimless variables; it measures them in sequence to root the difference in the data they contain, showcasing the conclusions. We use this kind of loss function to compute how proper our machine learning or deep learning model is by defining the distance between the appraised probability with our asked outgrowth.  Entropy is the number of bits needed to transmit a aimlessly se...

Different kinds of loss function in machine learning

  A loss function is a means of how sensible your forecasting model does in terms of being capable to prognosticate the awaited conclusion (or value). We convert the learning case into an optimization problem, define a loss function and also optimize the algorithm to minimize the loss function.    Different kinds of the loss function in machine learning which are as follows     Regression loss functions  Linear regression is a elemental conception of this function. Regression loss functions demonstrate a linear connection between a dependent variable (Y) and an independent variable (X); hence we try to serve the neat line in way on these variables.     Mean Squared Error Loss   MSE (L2 error) measures the average squared dissimilarity between the real and forecast values by the model. The output is a single number companied with a set of values. Our end is to demote MSE to enhance the delicacy of the model.   Mean Squ...
