Create A One Layer Feed Forward Neural Network In TensorFlow With ReLU Activation

What that means in the context of a neural network is that we have some layer, with weights W and biases b, and the output of that layer is going to be equal to the max of 0 and then W times the input x, plus our bias.

One for our weight, which we'll just simply call 'weights', and this is going to have a shape of 784 by 10, and we're going to initialize it using the Glorot Uniform Initializer (which is kind of mysterious at this point, but it’s the recommended way to initialize ReLU weights).

We are going to do the same thing, but this time, we're going to call it bias, and it's going to have a shape that’s equal to 10.

Just to give you an understanding of the context of the shapes, what's happening is that our x variable is going to have some number of instances, which each are represented at the 784 dimensional vector.

What that means, is that when we multiply x times W, the result is going to be a 10-dimensional vector, which we're then going to add our bias to that to get a 10-dimensional output.

Role of Bias in Neural Networks

in the activation functions.1 The reason it's impractical is because you're simultaneously adjusting the weight and the value, so any change to the weight can neutralize the change to the value that was useful for a previous data instance...

adding a bias neuron without a changing value allows you to control the behavior of the layer.

Furthermore the bias allows you to use a single neural net to represent similar cases.

Consider the AND boolean function represented by the following neural network: ANN http://www.aihorizon.com/images/essays/perceptron.gif A

the weights w0 = -3, and w1 = w2 = .5.

m = 1 and the AND function to m = n.

Machine Learning- Tom Mitchell) The threshold is the bias and w0 is the weight associated with the bias/threshold neuron.

Association between weight bias internalization and metabolic syndrome among treatment-seeking individuals with obesity

Across the world, individuals with obesity are viewed as stereotypically lazy, lacking willpower, incompetent, unattractive, and to blame for their excess weight [1].

In addition to experiencing weight stigma perpetrated by others, some individuals with obesity may internalize weight-biased attitudes by applying negative stereotypes to themselves and devaluing themselves due to their weight [4].

Consistent with research that cognitive appraisal of a stressful life event is more predictive of negative psychological outcomes than the event itself [8], recent findings suggest that WBI (a cognitive process) may be a more robust predictor of psychological distress than the experience of weight stigma alone [9].

Among individuals with and without type 2 diabetes, weight-based discrimination is also associated with poorer glycemic control, even when controlling for body mass index (BMI), depressive symptoms, and other relevant health variables [13, 14].

Increased appetite and/or physiological arousal resulting from these biochemical changes, combined with emotional responses, may contribute to observed increases in calorie consumption and binge eating in individuals who have been directly exposed to or experienced weight stigma [19, 20].

In several studies, correlations have been found between WBI and poorer self-reported health, increased binge eating, and reduced physical activity [6, 20, 23-27], suggesting that similar pathways to poor health may exist for WBI as with weight stigma perpetrated by others.

Although limited research has investigated cardiometabolic risk associated with other forms of internalized stigma (e.g., racism) [29], some studies have reported associations between internalized racism and greater risk of abdominal obesity, insulin resistance, and other indices of obesity-related health [30].

The Shocking Ways Large Women Are Mistreated by Health-Care Providers

review of studies published in the journal Obesity Reviews in 2015 surveying empirical evidence across multiple disciplines showed that health care professionals’ negative feelings about fat bodies can lead to misdiagnosis and late or “missed” diagnoses, negatively impacting patient outcomes.

Medical professionals’ underlying belief systems, driven by our thin-obsessed, antifat culture, can and does make their interactions with patients with obesity less productive.” As the problem of weight bias in health care has grown, so have resources to support those impacted by it.

Linda Bacon, Ph.D., advocate of the Health at Every Size movement and author of a book by the same name, also offers free downloads on her website that include letters folks can bring to health care providers to help them treat large patients with more respect and ultimately provide a higher quality of care.

Because fat women, like all people, deserve respectful treatment, and fat bodies, like all bodies, deserve care, we asked four fierce, outspoken, fat-positive women to share their experiences of fat-phobia and weight bias in health care.

There are remedies I’m not trying and some things happening for me that could be a problem down the road that I’m not getting addressed because I’m not going to the doctor.”—Jes Baker, themilitantbaker.com “I threw my back out three and a half years ago and I was in excruciating pain and the physician just looked at my chart and said, ‘Just take a couple of Tylenol.’ Doctors deny fat patients’ pain or minimize their pain or deny them pain management treatment because some doctors believe that some bodies—namely fat bodies—deserve the pain they’re in."—Sonya Renee Taylor, The Body Is Not an Apology “It does not matter how much you wish [your fat patients] were not fat.

If you are a health care provider who believes that a patient's weight is creating or contributing to some health problem—and there are cases where that’s a legit call to make—the way to negotiate that with a patient is not to come out with both barrels blazing saying, ‘You have to lose weight or your leg will fall off,’ because even if that’s true, your patient won’t be able to leave your office and lose the weight they need to lose to prevent that from happening.

My doctor quite transparently valued the weight loss enough to ignore the acute symptoms and said something along the lines of ‘You look great and your weight is coming down nicely so let's just wait and see how things are once your life settles down a little bit.’ A few months later, I ended up in emergency surgery with gallstones that had blocked my common bile duct.
