You can see that our model was able to identify two dogs in the snow. ET endobj Our overall approach centers around the Bottom-Up and Top-Down Attention model, as designed by Anderson et al.We used this framework as a starting point for further experimentation, implementing, in addition to various hyperparameter tunings, two additional model architectures. The layer is a softmax layer that provides probabilities to our 1660 word vocabulary. /R10 11.9552 Tf f Making use of an evaluation metric to measure the quality of machine-generated text like BLEU (Bilingual evaluation understudy). As the model generates a 1660 long vector with a probability distribution across all the words in the vocabulary we greedily pick the word with the highest probability to get the next word prediction. There are two main directions on automatically image synthesis: Variational Auto-Encoders (VAEs) [10] and Generative Adversarial Net-works (GANs) [5]. T* While doing this you also learned how to incorporate the field of Computer Vision and Natural Language Processing together and implement a method like Beam Search that is able to generate better descriptions than the standard.
