Astree 1.23 is released

Astree is an Amateur Telescope Making freeware to help with optical design and optimisation.

This software computes and shows the ray-tracing analysis of optical devices, having conical or polynomial surfaces, having reflections, transmissions, stops, analysis of the image quality.
There is a also an optimization module to enhance your optical designs!

The code sources are GPL, using Qt, feel free to send patches and request.
Source hosted at GitHub : https://github.com/edeforas/Astree

Latest build: version 1.23 (02/08/2020):
- New modern UI
- Minor samples fixes
- Added Nagler, FAA1 samples
- Better zmx import

Portable version Astree_1.23.zip (10.4 Mo)

BeeDNN new version released

BeeDNN is a deep learning library.

The git repository is https://github.com/edeforas/BeeDNN

The API is clear and simple, the goal is that every C++ coder can contribute, test, and use Deep Neural Network.
BeeDNN can run on small devices. It is even possible to learn directly on the device.
Please see at: https://github.com/edeforas/BeeDNN/issues for contributing ideas.
No dependencies needed, every algorithm rewritten in C++ from scratch.
To increase speed, ones can add the Eigen library (http://eigen.tuxfamily.org), instead of the internal matrix library.
There is also a GUI application (in Qt) for live tests.

Layers:
- Dense, with or without bias
- Gain, GlobalGain, Bias, GlobalBias, GlobalAffine
- Convolution2D, PoolMax2D, ChannelBias
- Softmax, Softmin
- PRelu, RRelu
- Layers and activations are decoupled and can be in any order

Activations (in alphabetical order):
- Absolute, Asinh, Atan
- Bent, BinaryStep, Bipolar, BipolarSigmoid
- ComplementaryLogLog
- dSiLU
- ELiSH, Elliot, ELU, Exponential, E2RU, E3RU
- Gauss, GELU
- HardELU, HardSigmoid, HardShrink, HardTanh
- ISRELU
- Linear, LeakyRelu, LeakyRelu256, LecunTanh, LiSHT, Logit, LogSigmoid
- TwiceLeakyRelu6
- Mish
- NLRelu
- O2RU, O3RU
- Parablu
- Relu, Relu6
- Selu, SQNL, SQ-RBF, SoftPlus, Sin, SinC, Sigmoid, SiLU, Swish, SoftShrink, SoftSign
- Tanh, TanhShrink, ThresholdedRelu

Loss functions:
- MeanSquareError, MeanAbsoluteError
- L2, L1
- LogCosh
- SparseCategoricalCrossEntropy, CategoricalCrossEntropy, BinaryCrossEntropy

Overfitting:
- Layers: Dropout, GaussianNoise, GaussianDropout, UniformNoise
- Regularizer: GradientClip, GradientClipTanh, L1, L2

Learning and optimization:
- Classification or regression, test and/or learn
- SGD, Momentum, Nesterov
- Adam, Nadam
- Adagrad
- Adamax
- RMSprop
- RPROP-, iRPROP-
- MetaOptimizer (V1)
- Class balancing if needed
- Keep best model vs epochs
- LearnMore mode
- Reboost mode

I/O:
- MNIST reader
- CIFAR10 reader
- csv file reader
- Network, weights and training parameters are saved in a simple .txt file
