Automatically generating a natural language description of an image is a fundamental problem in artificial intelligence. This task involves both computer vision and natural language processing and is called "image caption generation." Research on image caption generation has typically focused on taking in an image and generating a caption in English as existing image caption corpora are mostly in English. The lack of corpora in languages other than English is an issue, especially for morphologically rich languages such as Japanese. There is thus a need for corpora sufficiently large for image captioning in other languages. We have developed a Japanese version of the MS COCO caption dataset and a generative model based on a deep recurrent architecture that takes in an image and uses this Japanese version of the dataset to generate a caption in Japanese. As the Japanese portion of the corpus is small, our model was designed to transfer the knowledge representation obtained from the English portion into the Japanese portion. Experiments showed that the resulting bilingual comparable corpus has better performance than a monolingual corpus, indicating that image understanding using a resource-rich language benefits a resource-poor language.

We have developed a compact dual-band (2.45 GHz) power-amplifier module with a concurrent 8OZ.llaWg) WLANs. The proposed diplexer-matching network is three-dimensionally implemented i n an LTCC of 20 dBm at 2. 4 GH& and 1s dgm at 5 2 5 G H~ with an E V M 0144% for a 54-Mbps OFDM signal. Our approach of using a concurrent dual-band PA reduces the size and cost by D * almost half compared with using a conventional parallelIn this paper, we present a compact dual-band PA module with a single amplifier chain for IEEE802.1 laiblg output-networks are three-dimensionally integrated in a substrate, which enables us to reduce the module size to 5x 5 x 1.4 mm. The PA module exhibits sufficient output power, compliant with a strict error vector magnitude (EVM) specification, for both the 2.4-and 5-GHz bands, .
