  • Although Im not a fan of video games, when I saw this dataset collected byAman Srivastava,I immediately thought that it was great for practicing some of the basics of any Machine Learning Project.
  • In thisGithub Project,you can access the CSV files that compose the dataset and some Jupyter notebooks with the python code used to collect the data.
  • Among other things, we learned that a typical workflow for a Machine Learning Project usually looks like the one shown in the image below: – – In this post well go through a simplified view of this whole process, with a practical implementation of each phase.
  • Generally any machine learning project has an initial stage known asdata prepapration, data cleaning or the preprocessing phase.
  • In hisGithub Projectyou can access some of the jupyter notebooks with the python code that acts as the data preprocessing modules that were applied to get and generate the original dataset for our project.

  • The representation of linear regression is an equation that describes a line that best fits the relationship between the input variables (x) and the output variables (y), by finding specific weightings for the input variables called coefficients (B).
  • We will predict y given the input x and the goal of the linear regression learning algorithm is to find the values for the coefficients B0 and B1.
  • Because of the way that the model is learned, the predictions made by logistic regression can also be used as the probability of a given data instance belonging to class 0 or class 1.

  • From the picture above, we can see that a neural network consists of three components: the inputs, features in the data; the network, layers of neurons; and the output, the prediction of the trained model.
  • An example might be the (in)famous sigmoid function: – – The network is then many layers of neurons stacked together and connected up; the outputs of one layer are used as inputs to the next.
  • Since the activation function of each neuron is (normally) the same, this complex function must be built by adjusting the weights each neuron applies to its inputs.
  • Essentially it measures the difference between the networks predictions for a set of training data, and what the outputs should have been (the true values).
  • Now that we have a way of quantifying the current performance of our network, training it simply becomes an optimization problem of minimizing the loss function.
