In this we are ResearchGate has not been able to resolve any citations for this publication. trained on ImageNet, we demonstrate that either of these two issues may studied extensively. introducing a deep learning approach which can classify the sign Portions. If any of these parameters are changed when creating a sign, the meaning of the sign changes. This includes the Akan Dialect which is spoken by more than 40% of the Ghanaian population as well as in regions in the Ivory Coast. PARAMETERS OF AMERICAN SIGN LANGUAGE • The parameters of any language are those features used in the production of that language. Further, we leveraged transfer learning techniques by fine-tuning state-of-the-art network architectures pre-trained on the ImageNet database and improved the accuracy with a reported increase of 3.1%. The recent introduction of sign language into a mainstream school curriculum is an unprecedented attempt by sign language educators to break communication barriers between Deaf and hearing people in Ghana. We evaluate our proposed architecture on five highly competitive object recognition benchmark tasks. University of Toronto provides funding as a founding partner of The Conversation CA. For example, spoken English has long and short vowels, hard and soft consonants, and diphthongs. Ghana - Ghana - Daily life and social customs: Although the bonds of the extended family are an important factor in the social norms of Ghanaians as a whole, they tend to be much less pronounced among the urban population, where the trend is toward the nuclear family, especially among the professional classes and scattered immigrant groups.
