+
+## Running the Sample
+
+### Train a Base FP32 Model
+
+We train a model with the following parameters:
+
+* MLP Side
+ * Embedding size per user / item: 128
+ * FC layer sizes: 256x256 --> 256x128 --> 128x64
+* MF (matrix factorization) Side
+ * Embedding size per user / item: 64
+* Therefore, the final FC layer size is: 128x1
+
+Adam optimizer is used, with an initial learning rate of 0.0005. Batch size is 2048. Convergence is obtained after 7 epochs.
```bash
-sudo apt-get install unzip curl
+python ncf.py ml-20m -l 0.0005 -b 2048 --layers 256 256 128 64 -f 64 --seed 1 --processes 10 -o run/neumf/base_fp32
+...
+Epoch 0 Loss 0.1179 (0.1469): 100%|█████████████████████████████| 48491/48491 [07:04<00:00, 114.23it/s]
+Epoch 0 evaluation
+Epoch 0: HR@10 = 0.5738, NDCG@10 = 0.3367, AvgTrainLoss = 0.1469, train_time = 424.52, val_time = 47.04
+...
+Epoch 6 Loss 0.0914 (0.0943): 100%|█████████████████████████████| 48491/48491 [06:47<00:00, 118.90it/s]
+Epoch 6 evaluation
+Epoch 6: HR@10 = 0.6355, NDCG@10 = 0.3820, AvgTrainLoss = 0.0943, train_time = 407.84, val_time = 62.99
+```
+
+The hit-rate of the base model is 63.55.
+
+### Side-Note: Splitting the Final FC Layer
+
+As mentioned above, we added an option to split the final FC layer of the model (the `split_final` parameter in `NeuMF.__init__`).
+
+The reasoning behind this is that the input to the final FC layer in NCF is a concatenation of the outputs of the MLP and MF "branches". These outputs have very different dynamic ranges.
+In the model we just trained, the MLP branch output range is [0 .. 203] while the MF branch output range is [-6.3 .. 7.4]. When doing quantized concatenation, we have to accommodate the larger range, which leads to a large quantization error for the data that came from the MF branch. When quantizing to 8-bits, the MF branch will cover only 10 bins out of the 256 bins, which means just over 3-bits.
+The mitigation we use is to split the final FC layer as follows:
+
+```
+ Before Split: After Split:
+ ------------- ------------
+ MF_OUT MLP_OUT MF_OUT MLP_OUT
+ \ / | |
+ \ / ---> MF_FC MLP_FC
+ CONCAT \ /
+ | \ /
+ FINAL_FC \ /
+ ADD
```
+After splitting, the two inputs to the add operation have ranges [-283 .. 40] from the MLP side and [-54 .. 47] from the MF side. While the problem isn't completely solved, it's much better than before. Now the MF covers 126 bins, which is almost 7-bits.
-2. Install required python packages
+Note that in FP32 the 2 modes are functionally identical. The split final option is for evaluation only, and we take care to convert the model trained without splitting into a split model when loading the checkpoint.
+
+### Collect Quantization Stats for Post-Training Quantization
+
+We generated stats for both the non-split and split case. These are the `quantization_stats_no_split.yaml` and `quantization_stats_split.yaml` files in the example folder.
+
+For reference, the command lines used to generate these are:
```bash
-pip install -r requirements.txt
+python ncf.py ml-20m -b 2048 --layers 256 256 128 64 -f 64 --seed 1 --load run/neumf/base_fp32/best.pth.tar --qe-calibration 0.1
+python ncf.py ml-20m -b 2048 --layers 256 256 128 64 -f 64 --seed 1 --load run/neumf/base_fp32/best.pth.tar --qe-calibration 0.1 --split-final
```
+Note that `--qe-calibration 0.1` means that we use 10% of the test dataset for the stats collection.
+
+### Post-Training Quantization Experiments
+
+We'll use the following settings for quantization:
-3. Download and verify data
+* 8-bits for weights and activations: `--qeba 8 --qebw 8`
+* Asymmetric: `--qem asym_u`
+* Per-channel: `--qepc`
+
+Let's see the difference splitting the final FC layer makes in terms of overall accuracy:
```bash
-# Creates ml-20.zip
-source ../download_dataset.sh
-# Confirms the MD5 checksum of ml-20.zip
-source ../verify_dataset.sh
+ncf.py ml-20m -b 2048 --layers 256 256 128 64 -f 64 --seed 1 --load run/neumf/base_fp32/best.pth.tar --evaluate --quantize-eval --qeba 8 --qebw 8 --qem asym_u --qepc --qe-stats-file quantization_stats_no_split.yaml
+...
+Initial HR@10 = 0.4954, NDCG@10 = 0.2802, val_time = 521.11
```
-## Running the Sample
+```bash
+ncf.py ml-20m -b 2048 --layers 256 256 128 64 -f 64 --seed 1 --load run/neumf/base_fp32/best.pth.tar --evaluate --quantize-eval --qeba 8 --qebw 8 --qem asym_u --qepc --split-final --qe-stats-file quantization_stats_split.yaml
+...
+HR@10 = 0.6278, NDCG@10 = 0.3760, val_time = 601.87
+```
-### TODO: Add some Distiller specific example command line
+We can see that without splitting, we get ~14% degradation in hit-rate. With splitting we gain almost all of the accuracy back, with about 0.8% degradation.
