Black Box

Catherine returns to work after a month in treatment but can she keep her job? Esme's biological father needs his daughter's help and Esme finds out about the adoption. Ali discovers that Leo, Dr. Bickman's rival, doesn't have super-memory but is faking it due to a brain tumor. A new patient turns violent.

Dr Black loses her ring before her engagement party. The Mary Poppins Returns star gives a behind-the-scenes look at her new film. Catherine Black, a famed neuroscientist with a job at the Center for Neurological Research and Treatment, struggles with mental illness. I do not know why a lot of people don't like this show.

I think it is brilliant actually.

It shows hardships that a lot of people never will face in their lives. It shows you harsh reality. Im extremely in love with it and the acting is phenomenal. If it gets cancelled I will be devastated. I don't get how anyone could not like this show honestly it's amazing. This show is basic everyday life for some people. I really hope this show will continue and people will come to their senses. Props to the director, actors, and everyone involved you have an amazing show worth fighting for.

If it does get cancelled start a kickstarter or something because it is brilliant and I know I can't be the only one to think that.

Catherine treats a patient named Carrie, the baby-sitter of a hyperactive child. The doctors diagnose her with exploding head syndrome. With the help of her intern Leo, who has an outstanding memory and pointed out that this happens when the nanny is asleep, Catherine diagnoses narcolepsy. Meanwhile, Ian bursts into Catherine's office to kiss her but she doesn't reciprocate. He finds that she is hiding a spliff in her hands. Owen tells the staff members that Dr. Raynaud at a different hospital had a seizure while operating on a patient.

He lets everyone know to not hide any illnesses or they will be fired. Raynaud tries to commit suicide but Catherine is able to save him at the last minute. Catherine is still banned from seeing Esme, and is not allowed to attend her piano recital. Josh calls Catherine on her phone without speaking and transmits Esme's piano playing to her. Will is upset that Catherine has cheated on him, but then turns it around and said he cheated with his hostess, Delilah.

Delilah tells Catherine that she had repeated sex with Will. This leads to a messy argument with Catherine telling her to stay away. Ian had saved a pregnant and famous opera singer, who has a brain bleed. He has an argument with Dr. Pratt, the head of obstetrics, who wants to save the baby. He storms out and in that moment, Ian has to perform a caesarean section save both the mother and the baby.

Meanwhile, Lina is using a psychopathy checklist on Ian.

Catherine is treating a patient name Mona, who has a different visual perception on her left side. Catherine believes she might have tuberculosis and when Mona takes the turn for the worst, they don't know how to treat her without confirming that she truly does have it. They operate her on it anyway and it turns out she does have it and she is saved.

Another patient, Anna, who suffers from lesbian bed death , cannot recognize her wife, Claire. She is diagnosed with Capgras delusion , for which there is no cure. The intern Ali solves the problem, which Catherine deems as a rare skill. Regan allows Catherine to see Esme again, and wants to make sure that Esme knows Regan is her only mother.

Esme is doing a student film on her family and wants Catherine to be part of it. While viewing the video, Regan realizes that same nervous habit that Esme is displaying is the same as Catherine. The engagement is on; Will's staff at the restaurant is throwing the engagement party. Will tells Delilah that it was only a one-night stand and it will never happen again. Owen is playing chess and encounters an odd of sort man, Mike, who thinks he is the next Bobby Fischer.

Farrah Mahmoud, the psychiatrist at the hospital diagnosed him as bipolar and gives him meds. The meds puts him in a rage and Mike takes Farrah at knifepoint. Rather than a process of reasoning, we are asking, more or less, for the critical stimulus that caused a particular reaction outside of normal behaviour.

When people think about artificial intelligence, they typically seem to have in mind the first kind of explanation. The expectation is that the system made a deliberation and chose a course of action based on the expected outcome. Although there are cases where this is possible, increasingly we are seeing a move towards systems that are more similar to the second case; that is, they receive stimuli and then they just react.

With that in mind, lets dig into what we mean by a model, and the metaphor of the black box. The black box metaphor dates back to the early days of cybernetics and behaviourism, and typically refers to a system for which we can only observe the inputs and outputs, but not the internal workings. Indeed, this was the way in which B. Skinner conceptualized minds in general. Although he successfully demonstrated how certain learned behaviours could be explained by a reinforcement signal which linked certain inputs to certain outputs, he then famously made the mistake of thinking that this theory could easily explain all of human behaviour, including language.

As a simpler example of a black box, consider a thought experiment from Skinner: By manipulating the inputs, you are able to observe the corresponding outputs, but you cannot look inside to see how the box works.

In the simplest case, such as a light switch in a room, it is easy to determine with great confidence that the switch controls the light level. For a sufficiently complex system, however, it may be effectively impossible to determine how the box works by just trying various combinations. Now imagine that you are allowed to open up the box and look inside.

You are even given a full wiring diagram, showing what all the components are, and how they are connected. Moreover, none of the components are complex in and of themselves; everything is built up from simple components such as resistors and capacitors, each of which has behaviour that is well understood in isolation. Now, not only do you have access to the full specification of all the components in the system, you can even run experiments to see how each of the various components responds to particular inputs. You might think that with all this information in hand, you would now be in a position to give a good explanation of how the box works.

After all, each individual component is understood, and there is no hidden information.

Unfortunately, complexity arises from the interaction of many simple components. The only explanation for why the box is doing what it does is that all of the components are following the rules that govern their individual behaviour, and the overall behaviour emerges from their interactions. Even more importantly, beyond the how of the system, you would likely be at a loss to explain why each component had been placed where it is, even if you knew the overall purpose of the system.

Given that the box was designed for some purpose, we assume that each component was added for a reason.

The “black box” metaphor in machine learning

For a particularly clever system, however, each component might end up taking on multiple roles, as in the case of DNA. Although this can lead to a very efficient system, it also makes it very difficult to even think about summarizing the purpose of each component. In other words, the how of the system is completely transparent, but the why is potentially unfathomable.

This, as it turns out, is a perfect metaphor for deep learning. In general, the entire system is open to inspection. Moreover, it is entirely made up of simple components that are easily understood in isolation. Even if we know the purpose of the overall system, however, there is not necessarily a simple explanation we can offer as to how the system works, other than the fact that each individual component operates according to its own rules, in response to the input.

This, indeed, is the true explanation of how they system works, and it is entirely transparent. The tougher question of course is why each component has taken on the role that it has.
