🕹 Technology Data science Mathematics
  1. The Softmax function involves two simple steps: converting input values into positive ones using the exponential function and then normalizing them to fit in the range [0, 1] and add up to 1.
  2. Understanding the Softmax function becomes clearer when broken down into these two operations.
  3. By following the process of converting and normalizing values, the Softmax function can be easier to grasp.

🔬 Science Data science Machine Learning Wikipedia Models
  1. Wikipedia may not be the best place for beginners to learn Data Science and Machine Learning due to the unordered topics and high entry level.
  2. The concept of Likelihood function on Wikipedia made it difficult initially due to the absence of input variables, which is a crucial aspect to understand.
  3. Models in machine learning can vary from deterministic with input variables to non-deterministic like a coin flip, showing the wide range of possibilities for machine learning models.
