Yale scientists find TH gene in humans but not in chimps

Daily Mail

It's a chemical known to play a key role in pleasure and reward, and now it seems that dopamine may also play a part in human intelligence. A new study has found that the dopamine system evolved differently in humans than it did in great apes. The researchers found that humans have a generous supply of dopamine in the brain regions that help us think and plan – which could explain why we are more intelligent than other primates. It's a chemical known to play a key role in pleasure and reward, and now it seems that dopamine (artist's impression of neurotransmitter in the brain) may also play a part in human intelligence In the study, the researchers evaluated 247 samples of brain tissue from five macaque monkeys, five chimpanzees and six humans. In particular, the researchers looked at which genes were turned on or off in 16 regions of the brain.


Drone footage shows beluga whales frolicking in Canada

Daily Mail

Rare drone footage has captured up to 800 whales frolicking and socialising in the endangered channel where they come to give birth. The beautiful belugas were filmed as they sought out the safety of Lancaster Sound which lies off the coast of Devon Island, in northern Canada. The mammals majestically swirl through estuaries to their temporary home, playing and socialising in groups with a vocal chirp that earned them the nickname'canaries of the sea'. They were filmed by Sea Legacy, who are campaigning to make Lancaster Sound into a marine protected area to save the surrounding, wondrous wildlife and environment. If successful it will prevent oil exploration, additional tanker traffic and development of the area.

Handling 'Happy' vs 'Not Happy': Better sentiment analysis with sentimentr in R

@machinelearnbot

Sentiment Analysis is one of the most obvious things Data Analysts with unlabelled Text data (with no score or no rating) end up doing in an attempt to extract some insights out of it and the same Sentiment analysis is also one of the potential research areas for any NLP (Natural Language Processing) enthusiasts. For an analyst, the same sentiment analysis is a pain in the neck because most of the primitive packages/libraries handling sentiment analysis perform a simple dictionary lookup and calculate a final composite score based on the number of occurrences of positive and negative words. But that often ends up in a lot of false positives, with a very obvious case being'happy' vs'not happy' – Negations, in general Valence Shifters. Consider this sentence: 'I am not very happy'. Any Primitive Sentiment Analysis Algorithm would just flag this sentence positive because of the word'happy' that apparently would appear in the positive dictionary.


Getting started with Machine Learning in MS Excel using XLMiner

@machinelearnbot

Machine Learning is nothing but building a'machine' which'learns' from its experience. And, becomes better with experience – just like humans. We also learn from our experiences. Companies like Google, Facebook, Microsoft are using machine learning techniques at a larger scale. However, one common mis-conception people have is that they need to learn coding to start machine learning.


[D] Is there exists any attempts of creating NPC dialog system that uses natural languages processing? • r/MachineLearning

@machinelearnbot

I know that this looks like chat-bot problem, but as I think it must be a lot easier, because in a games there should be some boundaries of information that would be interesting for a gamer. So NPC should have an understanding of game important stuff only and just don't talk about any other things. This looks like very interesting application of machine learning but I never heard about something similar to it. The only thing I found is a Spirit AI with no information about how their technology works or any public demonstration. So, where could I find any research or projects similar to this topic?
