I came up with this idea when I was frustrated and overwhelmed at logging my emotional state several times a day to get a good understanding of my mental health and the factors that affect it. So I went about trying to make it quicker, simpler, and more efficient. I wanted someone to use machine learning to predict my upcoming emotional state so that I could monitor my depression better. As someone with bipolar disorder type II, it’s essential for me to keep track of my emotions and mood swings.
