Speaking giant panda: Secret language decoded as scientists set sights on hi-tech translator

Speaking giant panda: Secret language decoded as scientists set sights on hi-tech translator | Theory of Knowledge | Scoop.it
The secret language of giant pandas has been translated by scientists in China, discovering how the endangered species says things like I love you, I'm hungry and go away. The team from the China Conservation and Research Centre for the Giant Panda (CCRCGP) say decoding their language will aid conservation of the species.

After finding more than a dozen sounds pandas use as words, the team is now planning to develop a high-tech panda translator that will use voice recognition technology to understand what they are saying to each other.


Experts have been working on the panda linguistics project for the past five years, making recordings of adult males, females and panda cubs at the centre in various situations. According to China's Xinhua news agency, they managed to translate 13 different panda vocalisations.


Taiwan: Go to Bed Baby PandaIBTimes UK
Researchers analysed data on their voices and activities (such as eating, fighting and mating) to discover when panda cubs make a "gee-gee" sound it means they are hungry. When they say "wow-wow" it means they are unhappy, while "coo-coo" means nice or good.

Zhang Hemin, head of the CCRCGP, said: "We managed to decode some panda language and the results are quite interesting. Adult giant pandas usually are solitary, so the only language teacher they have is their own mother. If a panda mother keeps tweeting like a bird, she may be anxious about her babies. She barks loudly when a stranger comes near." He said the barking is interpreted as "go away".

When it comes to love, male pandas "baa" while females respond with tweeting noises. All these unusual sounds came as a big surprise to researchers, with Zhang explaining: "Trust me. Our researchers were so confused when we began the project that they wondered if they were studying a panda, a bird, a dog, or a sheep. [But] I

Eileen Otero's curator insight, September 5, 2015 12:39 PM

Start early to teach students how to reason, critical thinking will develop naturally. Foster their  inquisitive abilities by keeping them focused and there will be no need to memorize. It is possible to develop effective thinkers when they are involved in the learning process rather than just recipients of information.

Rationality and Emotional Biases. Do You Know What They Are?

Rationality and Emotional Biases. Do You Know What They Are? | Theory of Knowledge | Scoop.it

A common interpretation in behavioural finance is that rationality is the result of a pure cognitive process which can be behaviourally biased. In general, the bias has a negative connotation because it produces a distortion in the calculation of an outcome. When a decision-making process is cognitively biased the outcome leads to sub-optimal results or judgement errors. Roughly speaking, the subject might make irrational choices due to faulty reasoning, statistical errors, lack of information, memory errors, and the like. Differently, when the decision is emotionally biased, it means that the cognitive process has been influenced by feelings, affects, moods, and so on (let’s label these states “emotions”). This leads us to irrational decisions or actions. (Pompian 2006, Livet 2010, Mazzoli and Marinelli 2011, Fairchild 2014)

In this interpretation, cognitive and emotional processes are discrete and produced by two different systems: a cognitive and an emotional system. While cognitive biases are influences that affect rationality from within the cognitive system, emotional biases refer to those influences that affect the cognitive system from outside.

Learning about these 3 psychological biases could forever change how you go grocery shopping

Learning about these 3 psychological biases could forever change how you go grocery shopping | Theory of Knowledge | Scoop.it

You've been warned. 

Don't trust your grocer.

While they may seem reliable, the research suggests that grocery stores are only matched by casinos in their ability to make you do things against your own interest.

The unsettling truth about buying groceries is that from the second you walk through the breezy automatic doors, your brain comes face to face with a continuous, overwhelming desire to succumb to its most basic psychological responses.

Nearly all rational decision making goes out the window.

Stress, Brain Wiring, Empathy and Morality

Stress, Brain Wiring, Empathy and Morality | Theory of Knowledge | Scoop.it

Chronic stress might affect empathy and morality through its effect on neurotransmitters within the brain, primarily serotonin. Although the relationship between serotonin and depression is complex, we find that most effective anti-depressant medications work by raising levels of serotonin, implying that serotonin availability is defective in depression...

 

Greater levels of empathy, happiness and moral behaviour within occupations where stress and burnout are common for instance, within the military, medical and corporate sectors, could have wide-ranging implications on health, international relations and diplomacy whilst at the same time improving the moral compass of society as a whole.

Types of Business Analytics  

(1) Descriptive Models:  Descriptive models look into customer’s history to often classify prospects into groups and categorize customers by preferences and life stage. Descriptive models can help you uncover reasons for success and failures in the past, ultimately helping you make informed decisions in the present.   

(2) Predictive Models:  Predictive model uses rules and algorithms to help predict a given outcome from specified units. The objective is to assess the likelihood whether a similar unit in a different sample will exhibit exactly same performance. Predictive models often perform calculations during live transactions to evaluate risk or opportunity in order to guide a decision.  

(3) Decision Models:  Decision models describe the relationship between all the elements of a decision to predict the results. This model drives set of business rules to produce preferred action for every customer or circumstance.

This is our third of a series of posts in the papers published in an issue of Avant on Delusions. Here Rick Adams summarises his paper (co-written with Harriet R. Brown and Karl J. Friston) 'Bayesian Inference, Predictive Coding and Delusions'. I am in training to become a psychiatrist. I have also recently completed a PhD at UCL under Prof Karl Friston, a renowned computational neuroscientist. I am part of a new field known as Computational Psychiatry (CP). CP tries to explain how various phenomena in psychiatry could be understood in terms of brain computations (see also Corlett and Fletcher2014, Montague et al., 2012, and Adams et al. forthcoming in JNNP).
