Unsupervised sentiment neuron
> The model struggles the more the input text diverges from review dataThis is where I fear the results will fail to scale. The ability to represent 'sentiment' as one neuron, and its ground truth as uni-dimensional seems most true to corpuses of online reviews where the entire point is to communicate whether you're happy with the thing that came out of the box. Most other forms of writing communicate sentiment in a more multi-dimensional way, and the subject of sentiment is more varied than a single item shipped in a box.In otherwords, the unreasonable simplicity of modelling a complex feature like sentiment with this method, is something of an artifact of this dataset.
